HTC HD2 (Leo) Screens...

Hi,
I've gone and stupidly sat on my phone and now the LCD screen has a dark patch in the middle of it..
I've tried gently rubbing which reduces the patch temporarily and also heating up with a hairdryer completely removes the patch, but also temporarily...
I think final solution is to tear down and replace the screen, does anyone have any suggestions on where I can purchase a replacement screen? Or where I can obtain one at all?
Thanks a lot

I think you should send it to HTC for repair... might cost more than trying to repair it yourself, but trying to repair it yourself could lead to disaster if you don't know what you're doing. Much better to have a professional repair it.

I have exactly the same problem :-O

Have been looking around here and i believe this is the same problem as we have, He fixed it with a sucktion cup so may as well try that
http://forum.xda-developers.com/showthread.php?t=462102&page=13&=#122

Thanks for the link mate. I will try the suction cup idea also and see if it works.
I have called HTC to find out about repair, they said (I'm in the UK), that they will send UPS to come collect and then they will give me a quote, it can take about 5 days to repair if I agree with the quote and £20 to send back to me... But they couldn't give me a better idea on price, although he said because the phone is new it would likely cost "a bit"...
I'll look for a couple more days for alternatives to fixing then it could be heading off to HTC

well the suction cup didn't work for me, tried to use a hoover as well .... all starting to sound rather kinky.
Will be sending off to HTC instead now. Thanks a lot anyway.

Get insurance and get a new one. Or get it fixed.

Same problem. Looks like nobody is selling replacemet parts for leo yet I've manage to find digitizer, but not complete with lcd screen. Is the phone too new maybe? Hopefully someone will start selling parts soon..

there are screens for sale , i think it's about 50 usd or thereabouts. You might want o search around i didn't save the link.

Today I found one by accident
http://4u-kidi.com/info.php?itno=5460

Nope, that's still only the digitizer/ touch screen not the actual LCD screen which displays the picture

i guess you mean the tft lcd screen.

I did the same thing Xmas day and I ended up with a patch in the middle just like the photo I've seen in the thread linked earlier in this thread
after the initial shock thinking I'd broke it already, on closer inspection it looked as if I'd squeezed the liquid out of it so I thought why not squeeze it back?
all I did was press from the outside of the screen using 2 fingers either side of the spot and then quite firmly squeeze towards the spot. I did this in a circular motion around the spot thus forcing the liquid back into the centre. Eventually it was OK after a few directed squeezes and it had completely vanished so imagine my relief
probably a bit late now, gently rubbing as the original poster didn't work for me as that's what I did initially. Eventually I was brave and used some force but not enough to create more spots, just enough to force the spots away again and fixed it completely

Nexus 6 Screen Peeling Off

Hi Guys,
I was cleaning my phone the other day when I noticed an ackward gap between the screen and phone. I inspected it and I've just noticed the screen is coming off the phone. I had a look around and it's going from the bottom to the top. Has anyone had this problem?
BTW phone is has been in a pouch for 1.5 years and I can confirm has never been dropped. Given the phone is out of warranty what are the chances Motorola will repair this for free???

Man, did you manage to fix your screen? I am having the same problem here, just like you I was cleaning my phone when I realized the screen was coming off on one side. I know its been some time since you posted this but I am just wondering if you managed to fix it.

I saw this problem on other smartphones, you should check your battery, because on iPhones when it happens when the battery push and finally detach the LCD from the frame

Right, it seems to be that issue.
Some early N6 have had battery troubles. Their batteries inflated because of warm which usually makes the back cover taking off.
You seem to have the same problem but pushing the front of the device instead. (back may be well glued)
Don't know if Motorola will take it back. Furthermore, they have been selled to Lenovo since that, so it may be difficult. In Europe, when warranty is over (2 years), you won't get anything from them.
Just stick it back to its position, it's not a big deal. Maybe you'll have to buy some special tape for this.
http://www.ebay.fr/itm/Rahmen-Kleber-Klebepad-Klebefolie-Adhesive-Sticker-Frame-Motorola-Google-Nexus-6-/272109920217?hash=item3f5b03dfd9:g:VH8AAOSwCypWnlXM Something like that. Don't know if it is a special tape or a basic one..

What screen replacement do I need?

My Nexus 6 fell and the display broke. Not the screen but the display. The scratch's are inside. My device still works but I can't see anything and the touchscreen doesn't work.
What display/screen replacement should I buy?
I was thinking on buying this one: http://articulo.mercadolibre.com.mx/MLM-576031511-pantalla-touch-marco-motorola-nexus-6-_JM
Please check the link and tell me if it's the right thing to buy. Thanks in advance.
A pic of how it looks:

That's the right one.

That replacement has the frame too, if you want to save money and your frame is still in good condition you can just remove the existing frame from the broken screen, no need to worry about hurting the display as it's already broken so just break it loose, in pieces if you have to lol. Then just get one without a frame, just be sure to check the descriptions to be sure they include adhesive tape pre-applied or get a roll of 2mm 3M double-sided adhesive tape for $2 and do it yourself. While your at it you can also use the tape to re-secure your back cover after removing it if it needs any.
::EDIT::
Here is an example of one without a frame:
https://www.amazon.com/gp/aw/d/B00X...eywords=nexus+6+replacement+screen&th=1&psc=1
That seller it's a $40 difference in price without the frame. Also note how the speaker grills are attached to the frame, NOT the AMOLED. Keep that in mind when taking off your broken screen from the frame. If you are unsure if you can do it and feel safer just getting it with the frame, take 10 minutes before ordering and just try to seperate the broken AMOLED from the frame, if you succeed and find it by looking at it just how the new AMOLED panel would attach to the old frame then save $40 and get just the panel, it's already broken, might as well give it a shot, if you don't think you can attach the new panel to the frame yourself after removing the broken panel, order the one with the frame. ?

Thanks guys. I've got some more questions.
What process should I follow to replace the screen, should I dissemble everything? Any video tutorial you would recommend?
And, I've noticed that the phone doesn't heat up when I charge it as it did before (I have a Turbocharger), is the device ok? Is it normal that it doesn't heats up?

It's normal to have it not heat up when charging. Mine doesn't.
Jerryrig Everything has a good teardown video you can use.

What seems weird to me is that the phone usually heated up even if i wasn't using it (I guess fast charge) but now it doesn't.
Is there a way to know if it's charging or know the battery level other than looking and the screen? Because I can't see anything.

You should let the battery completely discharge, so the device turns off. That will help to prevent electrical damage to the components when you are disassembling the phone.

Letting the battery drain to zero is bad for the battery, for one. For two, the battery will be one of the first things disconnected, thus there will be no component damage.

Typed up a long response then posted and ticket was expired lol. All I can think of right now is the phone still works, just can't see anything. Let the battery die, call the phone to see if it's dead or rings/vibrates. After it's dead plug her back up and see if she starts, can call again to check if it's in fact booted into Android. Maybe someone else can think of a better way, I take it you don't have the LED enabled for charging so that sucks. Like the previous poster said, it is not advised to let the battery drain 100%, one time however won't hurt, just don't do it repeatably. Hope you successfully get her up and running again I still have my pre-order Nexus 6, never a screen protector, just a Seidio Dilex Pro case and not a scratch on the beauty, someone needs to make a SD 835 phone with dual front facing speakers before I upgrade!

anyone experience popping noise when pressing note 9 screen?

Hey!
Got a Note 9 last week and day after receiving it i noticed when holding the note 9 and pressing on screen in certain areas (near sides/corners/centre) it would make a popping noise, sounds like adhesive behind the screen not adhering properly or something like that. I got Samsung to replace with a brand new one and same thing with this one, it happens whether phone is on or off, it's definitely not rite as you can hear it very clearly, feels like some flex going on in screen when it happens as i can feel the screen kind of dip slightly when it makes the noise, but ok when it does not make the noise.
Curious to see if anyone else have had the same issue? gutted as loved it for the short while i had it but sending second one back now for refund as worried something will happen with screen further down the road and Samsung may not cover it. I know of at least 3 others who had this issue when buying same time as me.
Cheers.

Do you have a tempered glass installed?

Hey thanks for sharing that. This is the first link I got searching for this, I have it happen to mine note 9 too. It's such a bummer since I had it for only three days and will have to setup a new one from scratch if they have to replace it.

are you sure the s-pen isnt vibrating when you tap it on that side? remove the s-pen and tap it. i bet it goes away

Wow. No issues like that. I've had three Note 9s and all three have been perfect. I'd definitely return for a replacement. Weak or loose glue could seriously affect the water resistance, since it depends on a water tight seal between the screen and the frame. I'd never recommend using your phone in water anyway, but I at least like the assurance that if my phone takes an accidental dip. There's a good chance it will survive.

Yep real shame, my replacement was the same to, it's on way back, getting a refund, not worth risking something going wrong with the screen later down the road, i mean manufacturers do anything to not accept responsibility specially when it comes to screens. First one started on second day, it was great for the first day, replacement was doing it from the moment i took it out of packaging and holding it, it was worse than the first one.

agreed.

After studying the noise a bit more, it is definitely an issue with the glue. It will not happen all the time I press the screen, but it happens more often when the phone is a bit warm to the touch (e.g. charging the battery). Also, it appears to be along the side where the battery resides - I wouldn't worry about the battery itself, it just makes sense that the glue will get loose where it heats up more often (in my case, I don't stress the phone all that often for the other side where the SoC is to play a role). Anyways I'll be returning it tomorrow once the shops here in Berlin open 'cause now it's christmas break.
One extra thing that might be interesting, the back-side also has some sort of a glass-separation issue, at least it looks like that. Notice the circular smudge around and right of the DUOS label - I tried cleaning it but it comes back, I think the glass is separated at that point too, but just a tiny bit. I've had the phone for four days and haven't dropped/hit/scratched it AFAIK.

i agree with you, seems to be adhesive/glue issue, it did not happen all the time for me either but as you mention it, i noticed it more after recharging (when phone gets warm) so think you nailed the issue on the head to be honest.
I noticed it around the sides (edges) and the centre of screen, second one was even worse much more noticeable and was happening straight away after taking it out of box.
Something i noticed but never mentioned as wasn't sure but second one was the same, maybe it's normal but don't think it is, on the curved corners of the screen it appeared to me the screen looked slightly lifted not flush with the frame but only on corners.
I live in the UK btw. I was thinking a bad batch but seeing Samsung had a good deal on with cashback and discount i imagine they sold allot between the time i arranged to send mine back to getting the replacement which was a week so i imagine they would have been separate batches although i could be wrong.

Cool, thanks for the info. It's too dark in the winter days so it's hard to say if the glass is a bit off on the corners, but nevertheless, I will write back when I (hopefully) get a replacement one.
One last thing - you did speak directly with Samsung support? Did you buy it from their store or you just didn't want to bother with the store you bought it from?

I bought it directly from the Samsung online uk store. There was a discount direct from Samsung for students/people who work in certain industries so it could be bought for £699 (£200 off), but also they were offering £150 cashback bringing total down to £549, plus cashback by going via a cashback website meant i would have had it for around £504, also they were doing trade in so people could get even more off up to another £150.00 bring cost down to £399, then people got the samsung game deal thingy, don't play games myself but people can get a Fornite theme by downloading Fornite playing 3 games then you get the free theme, kids going bonkers for the theme, people selling the theme upto £100. So people could have the phone at a bargain price.

So I got a replacement, and just as you said, the display had the same popping sound out of the box. It happens like once a day, but since there is really no substitute for this device right now (stylus + good DAC, besides all the other great features), I'll keep using it and if it gets worse contact Samsung down the line for warranty/replacement. Decided to leave this as information if some other person happens to have the same problem in the future.

feel for you, such a shame and disappointing to happen a second time, it's a great phone, i did not want to risk it so sent second one back too. Fingers crossed you won't have any issues. Mine was happening regularly so like you say just keep an eye on it.

I don't have that issue even with the tampered glass on my phone.

i actually noticed it a few times.. like last night it was doimg it. sort of right above where the keyboard is in portrait mode..
it seems to happen when its really cold outside for me.. its not enough for me to have it replaced thankfuly

I can replicate this when I clean my screen with a microfibre cloth. It happens on pretty much all of the screen. I believe I can also see some light streaks in the screen when this happens. The popping sound happens regardless of the temperature of the phone. Will have to inspect it more to see if I can spot any other issues with the screen. I got mine in the UK just over a week ago. Apart from that I think the phone has been great so far. Not sure whether to replace it.

glad i sent mine back now to be honest, personally i would send back, as you say everything else is great apart from the screen popping sound. The worry for me is the screen might cause issues further down the road, screens are the biggest issue with mobile phones and manufacturers are quick to blame user and deny warranty.

My Unlocked US Note 9 does it too. Mine mainly does it on the right side near the middle. It's not enough for me to warrant sending it back; it still works fine and I don't see any screen issues when pressing on the screen. Also I bought mine used so I'm guessing the screen was replaced. If it gets worse, I guess I'll fix it then.

Screen replacement after water damage?

So... teardown videos on YouTube fooled me and I thought that this phone is water-resistant. I washed it under tap water (multiple times, actually). After the last time, the screen stopped working, but the phone appears to be OK — even the touch clearly works. I've already disassembled the phone and cleaned the connectors with 95% alcohol, but the screen still doesn't work. Is buying a replacement screen and hoping for a cheap repair the smartest thing to do? After all, the motherboard can also be borked.
EDIT: the screen is completely black

I've replaced the screen after dropping the phone. Was only a small chip in the bottom corner, didn't look much at all, but the screen was completely dead. I was in a similar dilemma of wanting to be sure it was only the screen before spending about $100 on a screen. I booted into fastboot, then connected to a PC, then done the fastboot devices command, which returned a valid ID, so I knew the phone wasn't completely dead. Also connecting to the PC and booting the phone, the PC recognised the phone was connected, though without being able to unlock the phone I couldn't check anything else. That was enough for me to go ahead and order the screen. Now everything works fine.

Thanks for sharing your experience! In my case, the phone clearly isn't dead, but I wonder whether some circuitry on the motherboard that's responsible for making the display work might be fried. Well... if that's the case, I can always sell the replacement screen after testing, but I'm not sure that someone will buy it for a good price.
Also... where did you get your screen from? On AliExpress, they are as cheap as $50, but most of the cheap ones are clearly some fake crap — TFT/IPS LCD, smaller than the original, fingerprint scanner not working... I guess I need to buy something more expensive. Have you noticed any difference between the original screen and your replacement?

It was 4 months ago I got mine from AliExpress, at that time there wasn't any of these cheaper ones for sale. Looking at these cheaper ones they are TFT, though it's not always obvious in the description.
One seller is selling both TFT and OLED and are clearly labelled in the options. So from this assume that all cheaper ones are TFT.
It is a bit of a minefield. I doubt that any of the sellers have the actual original genuine screens. It took me a couple of days to go through all the listings and determine which one would most likely be good quality.
I eventually went for this one, which was slightly more expensive than most. Now though it appears to have gone up about $15 from when I bought it.
https://a.aliexpress.com/_d7OqLlE
At that time it had the best reviews, which appeared genuine. There were others with a higher review count, which appeared to be just as well reviewed, but reading the reviews you realise they are fake. Many reviews, supposedly from the USA, written in very poor pigeon English.
Also saw some stores with high review count, but then realised that most reviews are for completely different products (a common trick by some Ali sellers, completely change an existing listing so a new product looks like it's got high reviews)
The screen is good quality. It took about 3 weeks to arrive, but it was about 2 weeks after I damaged it before I ordered. So it was around 5 weeks after I last used the phone before installing it. After that time it's hard to judge if it is as good as the original. To look at and use the phone you wouldn't think it was a non original replacement, to me it seems to be as good as the original, without doing a side by side comparison. As far as an oleophobic coating, I couldn't say, it's had a screen protector since installing.

I washed it under tap water (multiple times, actually)

Umm. What? Even with IP rated phones you don't wash it with water. IP rating generally means that its good for accidental drops into water or for use in light rain. Why on earth would you wash it? Yes, I know jerryrig says there's some water ingress protection but it doesn't mean you should wash it with water. It just means you're good for use in light rain at best.

Yes, I know. Very stupid. At least y'all can learn from it and avoid making the same mistake.

Well, I guess that even if it's a bit worse, replacing the screen is better (in my case) than dealing with an older/cheaper phone or throwing a nice sum of money on a phone in similar price range. I will report my experience after replacing the screen, maybe it will help someone. I'm definitely not going to find another guy with 9T (Pro) because of the coronavirus, but comparison with another high-quality AMOLED phone is another way to check the quality.

So... I wanted to order the screen, but when I checked whether the phone still works... it appeared dead. It charges, is visible in USB devices (but no fastboot etc.), the notification LED blinks, but that's all. It worked perfectly some time after the water damage occured, so I guess that the damage progressed. Yes, I didn't clean the phone thoroughly after disassembling it - I thought that the water probably evaporated anyway after using a heat gun, so, as I mentioned earlier, I cleaned only (easily accessible) connectors. Maybe it is something stupid (power button?), but it seems too good to be true. If I don't post another update, just assume that my phone died.

My k20 pro Disable screen problem
Hi xda developers
After wetting the phone with a hand sanitizer and using the same wetness of the screen, I played the online game and put it in automatic game mode and rested for a while...
After waking up, I noticed that the phone was turned off, which was turned on by holding down the power button, but the screen is off...
Currently, only vibrators and notification lights work for the phone, and the phone is organized by a computer.
Also, the phone is charged and its sound can be heard while connecting it to the charger, and its sound can be heard in the same way to lock the screen.
Does anyone have an idea?

my phone just take s swim in the river yesterday, now its has no display but still on and even the touchscreen is working (i know is working cuz its register sound when i try to touch it everywhere). it have been dead first but then turn back on with everything work normal. but after about half hour, the screen suddnly dead.
after tear it my self i found where the water coming in, its from the 3.5mm jack. other holes have rubber protection but the jack has nothing. they even put water dammage indicator below the 3.5mm module....
i have try few method like clean the board with isoprofil alcohol but no avail. now im waiting my screeen replacement and will try to fixit my self.

Hello! Had exactly the same issue. Did it work to replace the screen?
My phone got into the sea (well the sea went into it), nothing happened for a while, and then it suddenly went black. Is working (like i can still use it as alarm lol) but the screen is not. Same as BlueOner, i'm afraid is not the screen itself but something in the mother board, so I would love to know if any of you were able to use it after replacing the screen or i will end up with the same issue.
Thanks!

It's toast. Don't even bother. The sea salt is hygroscopic, conductive (with moisture), corrosive and -everywhere- now.
It not a question of if it will fail only when.
Tap water is similar but not near as aggressive. The smallest amount of salt (sweat) can change that if it gets inside too. Even so if the device >didn't have it's battery pulled immediately<, then completely turn apart and cleaned with anhydrous isopropyl alcohol it won't fare much better in the long term most likely.
Any water internally can cause massive damage quickly. Or the signs of damage can take months to fully manifest themselves especially if the battery wasn't quickly pulled.
Salt water is fatal because it's residue doesn't easily rinse off as well as what was stated above.
This is why manufacturer warranties refuse to deal with water damage.
It's the gift that keeps giving...
Occasionally you can get lucky if you act fast
My Buds case fell into my coffee cup and immediately crash dived to the bottom like the sub in Das Boot. Cream and sugar too.
I pulled it apart and rinsed it will RO water then with anhydrous isopropyl alcohol in less then 3 minutes. Got as much as the isopropyl out as possible without compressed air and allowed it to dry in a warm sunny spot. Couldn't disconnect the Li battery as it was soldered or spot welded in. After about 2 days of drying it worked and other a year and a half later still is working.
I am still surprised...

Hi. I got water damage. The screen can be turn on but its not responding at all. I can press the power button, the screen lights up, as normal. I just couldn't unlocked it. It wont accept any touch. Also i tried calling from another phone, sound okay, also led notification working.
I havent try the charging port yet.
Anybody have similar experience? Can someone explain my problem? Should i order new screen replacement? Im just afraid its not screen problem.

Read my previous post.
You need to dry it out completely.
