Hey everyone,
I've been lurking around these forums trying to find a solution to a few problems that my HTC One M7 has been having but have yet to find a solution.
It all started with the black screen problem where I could only see the screen on my phone by shinning a bright light on it. I decided to do a factory reset but that didn't fix the problem.
My next step was taking the back housing off my phone to see if any of the flex cable connections were loose. Since I've been tinkering around inside I've gotten some weird versions of different things to happen.
I've gotten the screen to be back to normal brightness without touch controls and I've gotten the phone to be completely working outside of sound. Right now I have all the flex cables and black antenna cable unplugged and decided to let the battery drain completely before I reseat all the cables, recharge, and try from scratch.
Just wondering if anyone has any ideas on some solutions to the problem or things I can try. I've also though about replacing some of the flex cables to see if that helps. Thoughts?

Here's my story:
I recently bought this phone for only $125 - not bad deal if you ask me. I knew from the beginning that the screen was a little mess up, even the guy I bought it from knew that. You would need a flash light in order to see what was on the screen. From any other point of view, it's just totally dark/black. So the guy was gracious enough to include a new lcd screen which he ordered to replace the old one. So I decided to undertake the task of putting it in myself. Once that was all said and done, I powered the tilt up and it was doing the exact same thing before I put the new lcd screen in, which was not lighting up the screen and it was still very dark to see anything.
With a flashlight, you can see that it's still working and the touchscreen works fine too. I think another person posted a thread with the same problem, but no one really replied back to him. Has anyone come across this problem before? Some have said that it's the flex cable that connects to the front d-pad and lcd screen itself is the cause for the back light issue. Any suggestions out there?
If I were you I'd try to figure out the pinouts for the LCD panel. Try to see if the Kaiser is outputting the necessary voltage for the backlight. Also try the opposite and apply voltage to the LCD to test the backlight.
Unless it is 2 back LCDs, I'm assuming there is a fault somewhere internal and not turning on the backlight.
I've never taken my tilt apart, but this is where I would start.
I wouldn't know where to begin to troubleshoot a device like this. Lol! It's fairly easy to take apart - there's actually a video on youtube that takes you step-by-step. I guess this isn't as common as some problems are, but I don't want to spend money having someone else fix something that could be so minute. And prices for some of the replacement parts are almost as expensive as what I bought the phone for.
When I took my tilt apart, physically, everything looked good from what my eyes can see. A little cleaning here and there, nothing major. The guy who had it before me flashed the rom to try and make it look like it had touchflo on it so I reflashed it back to the original rom software (or at least, whatever was on the HTC website). I tried doing hard resets, soft resets, rom flashing and everything, still no luck.
My Xperia X1 is currently experiencing problems. The screen no longer lights up!
I started experiencing this problem a while ago, when opening and closing the device.
Day by day everything went from bad to worse and at one point it no longer lit up!
At first I thought there was some kind of screen problem so I bought one new LCD off ebay.
I disassembled my Xperia carefully following a tutorial on youtube.com and replaced the screen. Nothing changed. The screen didn't light up.
The strange thing is that everything else worked! Sound, buttons, vibration etc. all work without a glitch.
I had gave up my hopes of reviving my device and for four long months it simply got dusty. That is, until I found this post :
http://forum.xda-developers.com/showthread.php?t=561151
I opened my device and realised that I have the same problems mentioned in that post.
Thus, in an attempt to solve the issues I opened my phone and took the following pictures.
Please can anybody confirm that I have flex ribbon issues and tell me what I can do to solve this problem once and for all? Can I fix it or do I need a new Xperia flex ribbon?
I can't wait to start using my 'old' device again!
Look like a flex ribbon issue to me. You can fix it by getting a flex ribbon of course. I've had 3 go out on me...thinking about giving up on this phone entirely.
As mentioned in the previous thread re: similar problem, the flex will always be the culprit in any device with slide or flip form factor, not limited to Xperia. Most of the repairs coming in are for flex damage, regardless of the device price and quality.
I had no issues with replaced flexes on Xperia, once installed they serve their life span (albeit short one). It is possible to reinforce the flex, provided your tape is a very fine one, it needs to run in particular place only, e.g. where it is physically rubbed and bent the most.
Hey guys i just bought a nook color and had it shipped to my country but i think i am already regretting it now.
The touch screen starts behaving very weird randomly at any times, it automatically registers touches and keyboard automatically typing own it own, and what ever i touch just goes straight to hell and this continues as long a i don't lock and unlock it again.
Even when i am reading it automatically starts zooming.
I was think about rooting it and installing a custom Rom, will that fix the problem? because giving it back to B&N is not an option for me.
Also i don't have screen guard, and the screen is always smudged with fingerprints, can that trigger this sort of behavior?
I'm using mine in Australia and have a similar problem but only when using the supplied USB cable to charge it.
I've heard stories about faulty USB cables which might be the case as I don't have this problem when I use the cable for my desire. The problem with this is that the cable isn't long enough for practical use and the supplied cable apparently has extra pins which would explain why it still discharges (although slower) when using my desire micro USB cable.
For now I'm limited to only using my nook without the cable plugged in but I'm thinking about finding another cable as sending it back to B&N and then paying to ship it back here isn't really a viable option.
Let me know if you figure something out though.
Well the one with usb cable is a known issue and u can still use it otherwise, mine just happens randomly at any time, its almost unusable.
Does installing a custom rom help?
It wouldn't hurt to try. I know some kernals make changes to the touchscreen sensitivity but I don't know whether that would apply to your problem or not. A nook is very easy to un-root anyways so as far as I know (and don't quote me on this), you should be able to return it if you absolutely have to.
Don't give up though. I'm loving mine and for the price it's an awesome little accessory when it works.
Hi,
Make sure to clean the touch screen - last night I had a different looking
smudge on my screen that was causing huge problems - as soon as I cleaned
it off, back to normal. Are you in a humid location? Condensation will cause
problems too.
Also you may want to search for 'calibrate' in the forums, there is a way to
recalibrate the touchscreen sensitivity, I believe that this is mostly for
low sensitivity at the corners though.
Here are two links I found:

My touch screen acts up as well. I turn the screen off for a couple minutes to "reset" it. It will work OK for a little, then it goes back to wonky.
Hey guys i finally found a solution to this problem, well my touch screen is behaving normally when its not not connected to the power cable. I hope thats a solution good enough for you.
Just go to
h**p://nookdevs.com/Recalibrate_the_NookColor_touch_screen
I tried all the custom roms but that didn't help very much, so i tried this on CM7
and so far my screen is giving totally normal tests results when not plugged in and lets hope that it stays that way.
My daughter had a similar wonky-screen problem when she plugged in a particular set of portable music player speakers. Not another pair she has, just that one.
And I was able to replicate it on my nook. It wasn't specific to her nook.
okay, it seems that my excitement didn't last that long but
After a lot of testing, it turned out that the only problems was my oily or moist fingers.
so i got a screen guard and tested it for more than two hours and i haven't had any problems yet. So even if i do see that happening again, once in two hours is not that bad.

I think I'll try this cause I have oily fingers as well and I'm getting the wonky screen issue while NOT plugged in as well.

Assumes you have ADB working via USB or wireless
So I've installed a shiny new digitizer on my D3 and I've barely been able to boot since. At first nothing but the back-light came on except one out of ten tries actually got me to the lock screen where it appeared to have frozen. Took it apart and put it back together again. At this point only the charging led comes on, screen is blank. Re-assembled again making damn sure all cables were properly inserted, same thing. Power+M does nothing. I confess I did rough up the cables a bit, looking under a magnifying glass I don't see any obvious tears however.
Anyone else been through this?
...i bought the same droid with new digitizer for parts on ebay.
Problem was the Flex Ribbon Cable.
On ebay is opprox for $30.
You had issues with booting also?
my problem was ...sometimes boot with display white, sometime white
New flex cable did the trick!:laugh: I have 890 installed right now, could someone kindly remind me of the typical procedure for installing Maverick or Eclipse from here? I know this ususally involves un-rooting, bootloader/recovery but I'm not sure which guides to follow and in which order. Thanks.
EDIT:Nevermind, I found the information in the post next to this one.
Hi there can anyone help me please on this matter.
My wife has a HTC One M7. last week the phone fell in to the bath. I managed to open the phone up and clean it.
The phone was taken apart and cleaned correctly using the correct circuit board cleaning solution (sorry cant remember the name).
I then ordered a new battery as the old one was not holding full charge. I also ordered a new screen + digitizer as the old one was cracked.
I have put everything together and charged the phone.
The phone charges correcrtly and has no problems at all.
When i switch on the phone it starts as normal and makes normal sounds etc BUT the screen is dead.
There is NO life in the screen at all even though its a new screen etc.
I know that the old screen is working and even using that i still get nothing.
Has anyone else come across this issue ?
Are there any guides to test the screen driver IC etc ....???
Thanks for your help in advance
It seems like that you have got a faulty screen.

MIght be a faulty screen as said above, maybe a broken or badly connected flex cable. And since the phone went into the bath, maybe a defective motherboard. Its very hard to tell.
as @alray said, it's hard to judge what's the cause of the dead screen, it may be one of the three causes.
so first, you can connect your old screen to the motherboard, if it can still work, to check whether the mother board was damaged or not
if the old screen can be lighten up, you can exclude the possibility of damaged motherboard.
second , you can connect your new screen to the motherboard again. Just be carefully and pay attention to the connector. Make sure it is connected correctly. If the screen can't be lighted up, you need try to use achohol or something else in a small brush to clean the connector. Handle gently to avoid damaging the IC. After that check whether the IC has lost some part or not. Then, if the flex cable or connector is fine, you can connect the new screen to the motherboard again.
finally, if the new screen still keep the same same situation. you can almost judge that you ordered a defective part.
May the steps above helps!
Hi there
the screen works fine as well as the connectors.
These have been tested on another htc one phone.
I have noticed that the motherboard connecter is damaged..... i will try to get some pics up later today.
Thanks
