Dimaond Gets Hot and Screen Alignment Goes Out

I have done a reasonable amount of searching on this and have not found anything specific to my problem so figured I should post a question.
I have an issue with my Dimaond when it gets hot generally either using Wifi or Phone Data connection that the screen goes out. Basically everything goes to the left side of the phone so if you hit the Task Icon in the top right corner you get the Start Menu. Phone is basically useless at this point and you have to wait for it to cool down. Has happened since day one and is generally worse when using it when charging. I was watching Utube on it the other night 5min video while on AC charge and it went out. I am running Dutty 2.5 Rom and 25.07 radio have tryed 25.08 and 25.05 no difference was happening when the phone had orginal HTC ROM as well. Also will happen on a long call if the screen is on.
Basically feel issue is hardware related and maybe faulty screen still under warrenty so wanted to know peoples opinion on weather I should send back. Problem is will take a couple of weeks and I don't really wnat to wait that long if I can help it. Also assume it would be best to flash standard ROM back, should I do anything with HARDSPL eg should this be changed back as well if I send it back.
And before anyone says it I have tryed searching this topic and have found lots about HOT dimaonds but nothing related to screen going out at the same time :-(
Thanks

I had this issue in my JasJam (Hermes) whre the screen would simply go white after a while of use and I would have to leave it for a while for it to work again.
Unfortunately it sa hardware issue and you should claim a warranty repair on it

I can't see how this could be a software problem so I figured it must be the screen eg hardware related. Would be nice to know if anyone has had the same issue with a dimaond... Seems we may be spending some time apart, just hope it doesn't take long to fix..

I've had the same issue
http://forum.xda-developers.com/showthread.php?t=428976
My first device had been replaced recently (i.e. today) by my network provider (o2) and the new device seems to work without any problems now even if it's "hot".
(i.e. default screen adjustment + creating heat by activating the phone, wlan, bt + recharging it)

I sent an email to HTC regarding the fault and they said it would have to go back for a warrenty repair. I brought it through a resellar so has to go back to HK from NZ so will be away three weeks uurggghhh... Just seems odd I don't have any physical damage on the screen but hte problem has been around since day one as I remember having the problem the first day I got it. Juyst seems to be getting worse and is easily reproduced by usiung utube over wifi gets hot and it is all over. Just wondering if I should put an offical ROM from HTC back on the device before I send it back as I currenty am running Dutty ROM, what do you think....

i put the original rom back on and they still found out the the rom had been flashed, and would not repair on warranty

yep, i also asked about this problem
http://forum.xda-developers.com/showthread.php?t=438733
there are some youtube video's of how the phone behaves
my phone seems to do it less frequently since stopping using panosha's rom
im using alpha zero 7 at the moment..
i've also noticed that it isnt necessarily a heat issue, my phone does it completely at random
yesterday i found though, that when the phone did the alignment issue, i gave it a good shake.. and hey.. its all aligned again?!
maybe it was just a fluke, it hasnt freaked out since..
holding thumbs

Hey,
I also have the same screen problem, but my Alignment goes to right.
If I press on the left side, a press on the right side is recognized.
Good to know that Im not the only one with this problem.
greets doena

I got my phone back a week ago replaced the screen has been away for over two months, complete disaster, anyway all sorted now and I have not had the problem since....

I had this exact same issue (out of the box).
It was a hardware fault and I exchanged it for another one.
Haven't had any problems since.

Hardware's fault ? Most likely not. I will give u an example of why I think it was software related. My device ran hot as well but I simply switched roms and now it's the complete opposite. Your most recent device most likely come with a different Rom in the phone.

Problem! Please help! G1 goes to sleep and doesn't wake back up.

I don't know what caused this.
I got my G1 today. It worked for probably 2-3 hours perfectly fine.
I had an app freeze (either Barcode Scanner or Lock 2.0) and had to do a full hard reset.
Now, whenever the phones screen darkens or I put it to sleep manually, it WILL NOT come back up.
I have factory reset three times now to try and get this to work.
When the screen is black, all buttons on the phone still light up and so does the LED indicator up top. I had my phone set to use a locking pattern screen at one point during one reset to test out and when the screen went black, I was still able to try and log in by doing my pattern. It unlocked, but still showed nothing on the screen.
Please help!
I've tried:
Turning Wi-Fi off
Turning 3g Off
Disclaimer: Yes, I've searched. I can find other users with the same problem but none of them seem to have a solution.
Phone is NOT ROOTED and has the factory ROM.
Update 1: Update: It only freezes/blacks out when I try to wake the phone from one of the front key buttons.
If I'm sliding to unlock, it seems to be fine.... (but if I've already tried to open from the front it doesnt)
Update 2: If I mash all the buttons in random orders for about a minute or two it seems to come back. Anyone have any idea?
Update 3: I'm thinking this has to be an issue with none of the buttons waking the phone up when closed. If I lock the phone with the "END" key, and then click the front "END" Key again, nothing happens. If I slide the phone open, and click it twice - the phone wakes up.
Update 4: Confirmed update 3. Phone will not unlock via front keys unless it's slid open (or open enough to trigger).
I would really, really appreciate help with this.

Hate to bump this, but I've added some detail on the top and bottom. Have to leave for work, hopefully someone might have an idea by the time I get back.

Well you can try to reload the factory rom or root it and try a custom rom and see if the problem still exist. If it is still happening then it would be a hardware problem and need to be sent in. And yes you will still be covered under warranty with HTC since the phone is still less than a year old.

I had a problem with exactly the same symptoms. It turned out that the SD card was cocked-up so home, core, and some other process would hang trying to read it and the phone would not wake-up the screen any more.
Did you try removing the SD card and seeing if that helps?

Removed the SD card and rebooted the phone.
No change ( still acts the same way ).
Did you factory reset after or was it an instant change?
I don't mind losing data to fix this.

Wouldn't I have to root to reload the factory rom? Is there a rooting tutorial based just on that?

If you use the official update you don't have to have root. There are some links on here. I'll see if I can find it for you.

https://android.clients.google.com/updates/signed-gfh-CRB43-from-CRB21.c88b03d2.zip
That should be it, but can't confirm since I'm on my work computer.

Some thoughts--may be useful, or not:
Mine was doing that too, but it was caused because I dunked mine underwater during an urban exploring mission. I dried it out, replaced the LCD screen, and everything worked until it would go to sleep. Then I had to do a variety of button mashes and opening the keyboard to get it to come back to life. Sometimes it just wouldn't come back. The problem grew worse over time.
If wiping and reflashing (no need to use a stock ROM) gets you nowhere, then I would suspect a deeper hardware issue. I see you bought it used, can you contact the seller?
If you want to check for water damage, take out the battery and look at the tiny circular sticker in the battery chamber--if it is not white, it has been water damaged. (And the warranty will not be honored.)
Other Lesson: No urban exploring with G1s.

The link didn't work, btw.

Zero water damage.

That's great news zeabrid! In that case, I agree with an earlier poster--you should be covered by warranty. Wipe and flash a good rooted rom, and if that doesn't work, revert to stock and demand a new phone.

Do you have a link to a guide that teaches how to do this (with the stock rom)? I can only see a few that're spread out.
I'm not entirely sure my phone can boot into safe mode/disk mode, so we'll see about that.

Another update: When I boot into safe mode, the same problem exists.
Edit: Just emailed HTC.

This can officially no longer be considered a software issue.
I just rooted and installed a standard ROM. Same issue.
It happens all the way at boot now, just realized this.

HTC emailed me back and told me to call them directly. Will do that tomorrow.
if I find a solution I'll post it immediately.

Alright, my phone is officially ****ed.
Restored back to the original rom.
New problem now: When I close the screen, the backlight goes out and doesn't come back on. (I can still barely see everything, but there's no light).
Calling HTC today.
Edit: Called T-Mo support. They suggested deleting programs to free up space (I only have 2 downloaded and to reset (already done)
=(
Edit2: Called and placed a RMA with HTC after talking to two of their customer support reps. Thankfully, they forwarded me up the support tier after only about a minute with each person when they realized I had already tried all other steps.
The RMA process was surprisingly easy. I have everything set up, and when I get paid (tomorrow) I'm going to ship the phone out. I was given an estimation of 7-10 business days for full repair and return shipping (which sounds great in my opinion - I've never sent anything in for warranty work before).
I'll update you guys once I hear from their repair team on whether or not I'm going to be covered under warranty (I told them that the phone was a gift to me), and if not what the cost is going to be. Like I said earlier in the thread, all water damage indicators are clear and I have unrooted my phone, so I should be covered hopefully.
Thanks to anyone who posted in this thread.

Yea it defitenly sounds like a hardware issue and needs to be fixed. Glad your getting it fixed and you'll be covered no problem.

Do you know if they charge return shipping if it's covered under warranty? I have to pay my own shipping there, and they had me put a credit card down on file in case I either bail when its already there or they need to charge for repair.

To be honest I don't know the answer but would like to say they would pay for it. But they would have to let you know of the charge before they apply a charge to a credit card.

wow its weird cause im just having a similiar issue now.. in landscape mode.. phone and back light work perfectly. but one i close the screen everything goes virtually blank, everything is running perfectly just the screen light wont turn on..
will try some of your previous methods.. hopefully it works on mine..=/
thanks, for the info zeabrid

Droid 3 screen stays black .

So the phone (XT860 Bell) has problems when I unlock it the screen stays black. The phone works though cause when someone calls I can still pick up as I know somewhat where the green button is. But for the rest I can't do anything.
The only way to get the phone back is to remove the battery and restart the phone. Then it works again.
Anyone else had this problem?

have you tried hard resetting it?

No will do so. But before doing that I thought maybe there is some simple solution.
After the update to 2.3.6 things went all a bit wrong I think.

If you got this after the update, I am quite confident data wipe will solve your problem. You can try wiping cache only first - this way you won't lose your configuration and might solve the problem. The update supposedly wipes cache, but maybe that didn't work properly while you were updating. Enter stock recovery and give it a try.

Hey thanks for the help. But just did a reset. Not sure what went wrong when I did the update. Did wipe. Annnnyways. Right now it's stable. Let's see if it stays like this.

Ok sadly the reset didn't fix it. It took a whole day to go black again but still happened.
Any other solutions? I am scared that it's a hardware failure...but let's hope not cause I am in Holland.

I have the droid 3 and the same exact thing is happening to me. Sorry to tell you this but it has to deal wit the connector between the keyboard and screen. I've taken mine to get checked by a "phone doctor" and they told me that. I will tell you this now ,since it is still in the early stages, it's going to get worse to the point that it will stay black. Get it fixed by a techy or get a replacement soon. Mine reached it's point today and I am going to need to get it fixed. Hope it helps.

Doesn't sound good man :-(......
Though it happened a lot the passed days since the reset ( knock on wood) only once. Do wonder why it happens less now.

Yea you can reset all you want it's going to go blank. I had to right the dial pad numbers with marker on the screen just to make calls. I say get it fixed or replaced soon

I've got the same issue here. I know the thread is old, but I'm from the Netherlands (just like eezdva) and would like to know how to repair this.

If you can't take it back and want to try to fix it yourself you need to search for a droid 3 flex cable. The one you want has the front facing camera, front sensors and earpiece speaker on it. Then head on over to ifixit for a teardown guide (sorry no repair manual yet, I plan on working on one).
I have to add that taking this phone apart to replace this part is no small feat, and it would probably be better finding a phone doctor to do it for you, or just getting a new phone.
When you buy the part, request an OEM part, I have been sent cables where the front facing camera displays sideways, or doesn't work at all. Most also don't come with the front button deflector, and that has to be transferred from the old cable.
Hope this helps

Ok . Well I don't really know what the problem is. But it went away. Actually it started I think after applying the update . I got myself another external sdcard . At a certain moment I decided to remove it and things cooled down. It now actually never happens anymore.

Well I gues you're lucky!
My screen sometimes starts all scrambled and the phone doesn't power on. Sliding the screen a couple of time sometimes helpes, but most of the time I don't really know howto get the phone working again. I think it's more stable when I leave the phone 'slided out' (don't know the right word now).
And I searched Motorolas website and found 2 reparing companies in the Netherlands. They both are authorized by Motorola, as of such I think this repair will be in warranty.
I do have to send it for repair. I don't want to take it apart because of what bitz_dv said. I'll let you know!

No Fix
When I was gone on a short holiday my college got a call from the 'authorized' motorola repair center. They can't fix my phone. I need to pay 11 euro to get it back and that's it. I tried calling them but there was no answer.
I sended my phone in on 22 may 2012 and now they decided they can't repair it. I spoke to Ted from Negri Electronics who told me to get in touch with Motorola as my warranty is still valid.
I'm a little confused, where should I go if an official repair center can't fix my phone but do tell me the repair is within warranty..
What can I do? Besides ordering the parts and take the phone apart myself..
I started my search for the flex cable... I did repair a N97 once, within the warranty period and later on sended it in and they repaired it under warranty....
Is this the cable I'm searching for:
http://www.globaldirectparts.com/Motorola-Droid-3-XT862-Motherboard-Flex-Ribbon-p/mot1040660.htm

I am from Netherlands, and have the same problem with the screen, looks like many users from Netherlands do.. coincidence?
When i jst slide out the keyboard , a little bit is enough, and the screen goes black ( black screen of death ) it doesnt power on with power button.
I looked for a flex cable at ebay, and it surprised me , that cable is also doing the front camera, and speaker... My front camera wasnt working too, and speaker made strange sounds many times, so it could be that cable, but not sure.
Check my thread, i have also uploaded a video to make it more clear

[Q] Phone starts and sounds but screen remains black, with backlight on!!

Hello all,
My Xperia was in a serious bootloop that I couldn't fix, not with pc companion not with flashtool flashing stock roms. So I gave up and sent it to the closest Sony Mobile certified repair store, it took them one month to tell me they couldn't fix it, they said they opened it, changed the battery and it still had the same problem so they also gave up and gave it to me, they did say the problem could be the motherboard. I'm now living in Brazil and getting a motherboard for the c6602 is impossible first of all because the phone was never commercialized here (and importing is impossible, it'd take 2.5 months and they'd charge me 200% of the part price, unfortunately that's how Brazil works ). Something interesting that happened is that when I got my phone back they had solved the bootloop issue but they created another issue, the phone starts makes all the sounds the screen turns on BUT all you can see in the screen is the black color, so the backlight is on but nothing shows up.
Could I be able to fix this via software? or the only option is changing the motherboard (or maybe fixing something on it)?
If any of you knows how to fix this I'd appreciate an answer.

Because I sent it to sony and they said the problem was the motherboard and the problems the phone's been giving are pretty random, for example at the beginning the problem was that it had random reboot each one with more frequency, it when from that to just work with the ac adapter connected, it went from that to a bootloop of just showing the sony logo and restarting, after I got it from sony the problem is that it boots app (without needing to be connected) it makes all the sounds like it was working perfectly but the screen is ON but black. So because all this I'm convinced it's the motherboard.

I see changing the battery didn't fix your problem.
I think it's so sad that this phone with just more than a year of life are getting this serious problems and sony isn't doing **** to help us. They keps my phone 1 month just to tell me that it couldn't get fixed, they said they changed the battery and all but still the same problem. I've reached a point when I just don't trust sony anymore, I'm getting a galaxy s4 on monday but still I wanna fix this crappy-phone.

Well, in my case it happened out of nowhere, I wasn't doing anything special with the phone..., I'm thinking maybe restoring the TA partition would fix something? I don't know... I found the motherboard for 80 euros in aliexpress

Touchscreen problem

Hello!
I've got a strange problem with my touchscreen's upper space. The notification bar can't pull down. I made a screen test under service menu, and the screenshot shows the result. I think, my guarantee expired last month, so i must made it at home. First, i try with a hairdryer heated uo top of the phone, the touch foil can push back .. unfortunately without success.
Beause the warranty has expired, eager to take apart the phone, I changed the film is already affecting other devices earlier ,. but this will be the last thing i will do. Before that, are there any "home trick" to solve that problem?
I changed so many firmwares, orfficals and customs. Problem stays the same.
Thanks for the help!

Is hardware problem. There are many threads here that discuss the issue. Only solution is to send your device to Sony repair or replace the digitizer yourself.

I had the same identical issue. First started with the screen getting random touch inputs and then the top area stopped responding. Mine is yet under warranty so sent it to Sony repair. They kept delaying it saying awaiting parts and then after chasing multiple times it was repaired and sent out last Monday. Says case and display as replaced. Yet to set it up.. contemplating between Kitkat or leave it on Marshmallow.

Yep sux, mine touchscreen was bogus too, send it in to be fixed under warranty

I have three z3c on my house two has this problem.
Is a sw trouble can't use screen protector....
Enviado desde mi hilo y dos yogures desde PetaTalk

I came on here to look for this. Happening to mine as well.
The *strange* thing is though when it's on the lock screen the swipe down works fine.
Unlock and starts being temperamental. especially in apps.
Just out warranty by about a week. Great.
I've installed Nova launcher as that lets me open notifications by double tapping the screen. This doesn't work in apps but does on the desktop. Anyone have any idea how much this costs to be repaired?

The reason it works on the lock screen is that the hitbox for the notification bar is larger on the lockscreen. I had the same issue, luckily my phone still had one week of warranty left and SONY replaced the whole phone for me within a week for free. I sent it to official SONY repair centre here in Dublin, Ireland.

Hey Guys. It happens also for me. From 1 hour to another! And actually the fist hardware probem I ever had with Smartphone. Congratz Sony!
Its clearly visible that an complete vertical area from top to bottom is not or only very sporadic accepting the finger movement.
So Service Center is the only possibility? What do you think? tried already complete stock and factory reset.
Actually its logic to send it to Service but if you have comments or maybe the same error please let me (us) know.
Thanks for any comments in advance.

Same thing is happening to mine, almost two years to the day after I bought it. I'm gonna try taking off the screen protector to see if that makes any difference, otherwise it's phone upgrade time (which is not a bad thing). Started a week ago intermittently and now is pretty much permanent. PITA.

Mine is now a week at the service center. I bought it quite late so one year guarantee left for me. Will report what they did... But it is a bit scary how many z3c went defective because of touch screen problems...

I solved the navigation bar problem using Xposed + "Xperia/AOSP NavBar Buttons" module. Just increase navbar height to 150% and it's done. For the notification, bar install Nova Launcher and use the home button action (free) or the swipe down gesture (paid).

Just to give you an final report: They changed my phone and I received an new one...
And the replacement was send right after I asked for ETA. All in all it took three weeks.
So maybe (if you phone is at repair in guarantee) asking and asking would speed up things and the possibility to get a new one is rising...
Now I have a white one (instead of black) but its OK...Feels a bit more like a new phone because of new color Thanks goodness not green or red...
The letter said that chaning to higher one or to another color is part of sonys replacement policies.

Hi again! The story continues. My guarantee expired after one year, but my warranty was good. ( it's 2 year ) I sent my phone to the service center. After two weeks, the service center changed my phone to a brand new xperia x compact.... I hope this will not be wrong with the display. In any case, I was pleasantly surprised to Sony right now.

What seems weird to me is that several people report the same problem at the same time. E.g. it start with random "clicks" on the taskbar and then the touchscreen area of the taskbar stops working. This is happening around the time of 2 years of using the phone. Really weird.
I like the phone but this is just disappointing. After the nougat update fail for the z3 / compact (first claiming that it cannot get nougat because of missing vulkan support which turns out to not being required by the compatibility definition document for nougat) and now the touchscreen fail, I'm pretty sure not going back to Sony for a phone. So sorry.

I have this problem too. The notification bar stopped working in august. And since yesterday the bottom of the screen doesn't work too, so I can't use the on-screen virtual buttons :crying:
I'm afraid this is getting worse and worse.

I've faced this problem too. I buy Nova Launcher to use it's custom swipe down gesture as notification bar issue's workaround.
And i enable Glove mode on Display settings as on-screen virtual buttons issue's workaround. Of course it does not comfy.
As a newbie, i believe this issue caused by the software/MM. Maybe i'll try to revert back to LL or KK or another rom, since z3c would not get nougat update

I can add this to the list of defects I had as well.. Send mine back under warranty about a week ago, hope i'll see it back soon.. Nova Launcher is a good option but the xposes AOSP navbar seems like a better solution, if you have exposed.

I too have this issue with top portion of screen. Any day fixes other than buying new screen (1 month out of warranty)

I've updated to the Z5C and shelved this phone. I picked it up today to check which firmware it has and alas, the touchscreen simply crapped out out of the blue. This is unacceptable. The phone jack also went bad before I switched. I'm really pissed and I don't know what to do. I bought this phone two years ago. Look at the touch draw test to see where it died. How can a touchscreen go bad out of nowhere????

Hi everyone,
I'm facing exactly same problems described in this thread.
I bought my green Z3c in Italy less than 2 years ago and I still have the invoice, but I'm wondering if the warranty is still valid.
I'm wondering because I broke my glass during a trip in Australia and I replace it there, in a store, with original Z3c LCD touchscreen and frame but black colored. (I no longer have the store LCD receipt though)
What do you think? Can I consider my device to be under warranty?
Regards.
