htc hd broken display

I'm very disappointed, I'm having problems again with my htc hd. At first it blocked and it wouldn't want to turn on. I sent it back twice under warranty with the same problem and in the end they replaced the motherboard.
I thought that now that practicly i have a new phone i won't have any problems with it. But surprise! The display just got crazy. When i touch the screen in a spot it activates in a completely different spot. It's the same thing on the entire screen. Check out the video.
Anybody had this problem? Oh, by the way the phone didn't managed to fall from somewhere, or get hit by something or anything else.
PS: Next step: htc snap. No touch, no worries. I hope so.

Could be that your screen alignment is not setup properly. Have you tried setting this up?

had EXACTLY the same issue. left my touch for an hour and when I cam back to it it was like that.
I sent it back to HTC and the first time they cancelled my warrenty because it had "illegal" software on it. I had Hardspl on there, nothing else.so when got it back I returned it to its origanol configuration and sent it back again. Its interesting you got a new motherboard in yours as they claimed that was the fault in mine and told me it was BER (beyond economical repair)
I am not going to accept their bull%$$^ and if it comes back again without repair i shall resend it again & again (cost me nothing) until either Carphone Warehouse replace it under warranty or HTC fix it under warranty. My phone was less tha 2 months old and NEVER been dropped or mishandled. It was in pristine condition

If you have removed everything illegal from phone, i.e. returned phone to original SPL and rom and then returned phone under warranty, they are obliged to fix it or send a replacement under warranty as your phone is only 2 months old. If they fail to comply I would threaten them with Standards agencies and Watchdog.
Let me know how you get on.

Thanks for the reply. The problem is that i can't get there. Is way to down and i practicly can't click it.
Is there any other way to get to screen alignment?

Couple ways:
1. Manual way by navigating to Start > Settings > System > Screen
2. By performing a hard reset. After you have performed a hard reset and rebooted device you should be prompted with a setup screen allowing you to align screen and then enter date/time.
Have you tried performing a hard reset?

I just did. Unfortunatelly the problem hasn't been fixed. The display isn't working good at all.
I guess i have nothing to do but to send it back under warranty again.

After your hard reset were you not able to screen align?

I had the same issue. Without any impact or misuse the screen started becoming misaligned. Re-aligning the screen would only work for a short time before it again went crazy - it gradually got worse until the phone was completely unusable.
It turned out to be hardware fault with the touch overlay. I sent it back and HTC repaired it under warranty.
Having searched a lot around the web, I think this is a fairly common fault.
The tricky part was doing anything with the phone when the screen doesn't work. e.g. removing the "illegal" software - hardspl and the cooked ROM. In the end I used some software called "EveryWAN remote support". This is free software that lets you operate the phone through your PC. You could try using this to get to the align screen. Good luck.

Update:
I sent it back again via CPW and they put a note on my file that although the software may have been "illegal" there is no way it could have caused the fault to the phone, I also restored it back to the origonal configuration so they could see it was a fault on the phone itself and not software.
Well, to cut a long story short HTC have accepted responsibilty and givenme an exchange unit and reintated my warranty so I am happy as Larry.
All I can say id dont give up on getting satidfaction out of HTC. in my opinion they have a duty of care to us as customers even if we put "illegal" software on our phone.

3. pressing "VolumeUP" and "VolumeDOWN" and "Touching the screen" all at the same time -- gets you to align screen.
ABOUT THE SCREEN PROBLEM:
judging by the problem you have it might be that some of your digitizer wires arent working (broken or not having a proper contact) -- if the problem started immediately after you got your HD back from service, - then it might be that the guys there broke a wire of digitizer or didnt attach the wires to its connector-- Digitizer has 4 wires who connect to device (if only 3 or less wires work-- incorrect screen response and no way to align it) .... (sory for the english but I dont know all the names of the stuff i wish to mention )
I suggest you to take it to service and explain them the problem and say that it might be the wires of digitizer , because of the last service!
Good Luck!
oh and HTC Snap aint worth it- HD is best!!! you just had a bad model, which is one of thousands(you may consider yourself as a chosen one )

My display just stopped working. Completely. They changed the whole front part at warranty and now it works way faster while browsing it. It took 15 days to replace the part. Unfortunately I have other issues with the phone but I don't want to be off topic here.

I RMA mine due to black screen. After they returned the darn phone (after changing the bezel and motherboard - you would think it is as good as a new phone), Wifi and Bluetooth does not work. Gonna stick right beside the router or bluetooth set to detect...
I am going to condemn HTC soon....

Thanks, forgot that one

I have this problem, it was just this week - christmas day onwards. It's random as to the problem being there.
Bought the HD from mobiles.co.uk without cancelling the insurance.
it will always work again for a short period if I manage to get to the align screen config.
I'm running the stock rom (never flashed)
I have done some TF3D changes. (background, icons, etc.)
It can randomly decide to work again, and then randomly not work.
found out the volumer control and tap screen shortcut to the align screen config, so that should help me get it back quicker.
It's like the lower down the screen I tap, the further away it is from what actually sows on the screen. the call home back end buttons dont work when it is not aligned.
I'm in the UK and the date of the insurance letter is 15th June 2009 on an 18 month contract with O2
What should I do?

It happens more often now, and is getting annoying.
it can end up lower down the screen to now be out either above or below it
I really need help with it.
I ended up ringing the landline phone, and possibly (almost certainly) waking up people in the house struggling to turn it off.
A solution is needed pronto.
It can go wrong within seconds of doing the alignment thing

[Q] [Help]HS2 Wont start after new LCD

Hello all.
I have a HD2 that I havent done anything with, exept getting and installing some small programs.
No new ROM, no attempt to install W7, its more or like a Virgin.
However I made a fool of me, and managed to damage the LCD and finally got it changed. Got the Phone back from the company (MBlue Ltd in UK), and tried to start it up. But No....
Pressing ON, the phone vibrates, gives some light in the screen, sort of like you see its ON its a "white glow", but you dont get any more. The Jingle comes on, theres light in my buttons at the low end of phone, and NOTHING more.
I have had it on for long time, but nothing....
When I finally sendt the phone away, the battery was discharged, but as I have a new battery I put that in, and it charges and all.
Ive studied this thread: forum.xda-developers.com/showthread.php?t=638210
But as I CAN charge I fell that Im somewhat related but not fully in the same situation as the Original Poster there.
# Could it be that my phone somewhat has gotten overheated or anything else?
# Is the only and best solution to send it to HTC and let them look on it?
Ive tried to HARD and SOFT reset, but still nothing.
[EDIT] Connecting the phone to my PC, It is recognised and its recognised as a HD2 T8585
Looking more and reading more on the Forum I suspect theres a problem in the connection between the "fx-card" and the screen. (stupid way of saying it though)
Glad for any input here. Thanks in advance.

Does your computer synchronize with your phone(connecting to activesync/mobile device center)? Then it is booted in Windows Mobile, the possibility is that the screen is broken then.

I thought the Screen might not be properly connected, or broken yes.
I better get in contact with the repair company.
But if other too have opininons, please bring em on... ;-)

Returned to repairplace, they fixed it.
My best guess is thy didnt check their own repair so they had to connect/fix something.

Good point, they're responsible for their repair: it is better this way because it's possible they damaged something while repairing and that part, if needs replacement, it should be their obligation, not yours!

problem with optimus 7 device. would appreciate the help

Hey,
So here`s my problem.
2 days ago my phone just switched off, no warning, no nothing, and won`t switch on ever since.
I already looked around for people that may have the same problem, but every thread talks about the device that won`t go pass the logo screen. It is not my case. My phone doesen`t even show the logo screen, nothing. You can press the power button for as long as you want, it just won`t start. At occasions, it starts up by itself, only for a minute or two and then turns off again.
At first i thought it may be a software problem, so I`ve cold started it and reset it but it didn`t make any difference.
After, I`ve thought... maybe a battery issue, so I`ve talked with a pal that has the same device, switched batteries. Apparently his phone started with my battery just fine, but mine didn`t work with his either.
Does anyone have a clue about what`s happening?.. If yes, please do share. As much as I like having a phone with a mind of it`s own.. it`s just not dependable XD
Thanks

Probably just broken / defective - if under warranty go and ask for repair or replacement (money back probably). If not under warranty sell as broken or throw to the bin - not to worth repair in my opinion.

I spend the same thing to my myself, LG stinks.
Sent from my HTC ONE V using xda app-developers app

Thanks for answering.
Yes, it was a problem with the motherboard.. got it fixed on warranty. Now I barely use the phone, of fear that it will break againXD. Looking forward to selling it while it`s still functional.

I've got mine just back from repair (second time). It use to randomly reboot, now I hope it got repaired ("faulty electronic components have been replaced" - but I don't know what exactly). What I realize is MAC address change. But as they changed firmware from 1.1.8.10 to 1.0.16.10, I wonder if that's why it has new MAC? Does new MAC address means that some component was replaced ? IMEI does not change.

Screen wont turn off and charging issues

Hi. Hope someone could kindly help me!
My Note 3 is not turning off the lock screen. Its always on!!. If I press the power button the lock screen comes on, after few seconds it quickly flickers (like its trying to close) but turns on again. Its ongoing loop. I have resetted it dozen of times, factory reset now as well but issue remains. I just cant turn the screen off!
It also doesnt want to charge all the time. Is this a USB port issue? I hate to think I need to send it to EE for repairs as its over 1,5 years old and will take at least 2 weeks I think... (cost?)....

Hai,,
Samsung have 2 year warranty within Europe and I dont know outside of Europe, sorry.
But for the phone, if you know that phone havnt been water damaged there shouldn't be any problem, (ALOT) of the Note 3 is water damaged today so be careful with that...same goes if your phone is rooted, could end up paying for the repairs instead.
Phonewise: Broken PBA/powerbutton and a bad USB port..

Hi Im in UK.
However there is absolutely no water damage at all. Its been very well cared for, it looks like brand new including the screen. Thanks

Best would be then to find an authorized samsung service center and either call them and explain your problem or just send the phone to them.
And make sure to have your warranty paper near hand. They might ask for it ://

Hi. Yes tried without the lockscreen - same issue. Also with another Lockscreen,,, with no help. The screen just doesnt turn off!
Wonder if its a hardware issue - eg usb port? I tried to clean it the best I can, but doesnt help.

As said Samsung offer a limited 24 months warranty .
But root or custom roms etc will void .
The vendor EE is an alternative but under Sale Of Goods Act you will have to prove that the product should have lasted longer etc via an engineers report .

Hi all
This is what I done. I took the Note 3 to Samsungs repair centre. Shortly: they said they probably need change the usb port and screen and will be done by end of day. No calls nothing. Next day I pop in they say its not been done as there is water damage!!! They show pics of corrosion inside the phone, I believe and leave. They quoted fix it outside warranty to £180.
I go to ebay and bought a new usb port for less than fiver. Changed it today, was 15min job. The phone charges ok I think now, but the screen still not turning off!!! Im gutted.
Interestingly I didnt see any sign of that corrosion when replacing the usb... hmmm... cheeky Samsung repair guys? The phone never seen water, believe me.
Any ideas whats next... I cant afford a new phone or buy new screen.
Thanks

Water damage is part of the repair check list and immediately voids warranty .
Not much you can do if you cannot buy a screen .
Plus water damage may be internal damage and not the screen at all .

I do agree with what you say of course. However I never dropped the phone in water. I did buy the explanation of shower mist or something if the phone was nearby, they showed me pics they took inside of the phone: however when open it up this morning I didnt see any of the corrosion. Have I been tricked or am I blind... :/

LG randomly overheating and won't stay on - No previous heat issues

Hi, I have a LG K20 Plus. I currently can't turn the phone on, so I don't have much software information to give you. The phone was bought at T-Mobile (Metro by T-Mobile) and I had a SafeLink sim card and a 16 gb micro sd card inserted when the issue started. I have since removed both. It says Qualcomm snapdragon on the screen when it starts. It was also rooted and the bootloader is unlocked.
I broke the screen on my phone and I decided to do the repair myself. I have done about 7 or 8 screen replacements and I actually did this phone a year ago with no issues, so I felt I could manage this one as well. I bought an entire display (from ebay) and switched it out with no problems. Initially it worked great! I used it for a few days before realizing that I had no sound. I opened it back up and noticed the loud speaker had fallen out. I found it, put it back in, reassembled it as I normally do and turned it on.
NOTE: when I was reassembling it the second time, I actually tried to put a screw in a hole that wasn't a screw hole. I used a light to normal amount of pressure but I didn't force it. I think it's the hole where the moisture detector is. Picture #1
I turned it on and right after the logo screen I got a message that said "High temperature detected Powering off for your safety" and it immediately shut off. The phone does appear to charge normally but it won't stay on. I did a factory reset (I'm not sure if it's still rooted but the bootloader is still unlocked). I also switched back to the old (broken) display just to check if that would work. I couldn't see any difference in the shielding but I switched them just to be sure. I bought a new battery and installed it. I took a q-tip and 95% Isopropyl Alcohol and cleaned pretty much the entire motherboard, paying special attention to the battery connections. After each one of these things, I tried to start it with the same error message immediately upon start up.
NOTE: At no point has the phone every physically felt hot or even warm. I don't think it's on long enough for it to get hot. But something is wrong and I have no idea what it is. I, literally, took the phone apart, put in the speaker and put it back together in less than 5 minutes. Could it be I just bumped something and knocked it loose?
I searched for any information I could find both here and with google but there is next to no information on the LG K20 Plus. I did find some information on the LG V20 that had overheating issues, and that has been all the luck I've had. I watched several videos and it seems the solution is to apply thermal paste. But my phone doesn't have any evidence that thermal paste was ever on it. I went and bought some but I have no idea where exactly to put it or even if it's needed. Most videos showed people using some kind of aluminum foil but I'm not sure if that is safe. I have several old phone laying around and I managed to get some of the silver tape and a copper square thing but, again, my phone did not have these things to begin with. I don't want to start adding things only to make it worse.
There is a slight difference of the tape that is on my phone now (the display I just bought) as compared to the old one (broken display). Picture #2 Again, I have no idea if that means anything but I thought it worth mentioning. Picture #3 is how it looks now as if I were going to put it back together. Picture #4 is the part (don't know name) where the videos show to apply the thermal paste and the shielding.
I'm really at a loss as to what to do next and I can't really afford to take it in to have it repaired before next month. If anybody has any insight or answers as to what happened, I'd be very grateful for your help. I'm sorry for the long post. I just wanted to tell you everything I have done in detail. Thank you

If you're using Kernel Auditor or any other kernel adjustment simply reset to default and use only ondemand or interactive. There's also options for the thermal portion of the kernel, don't mess with those. If VCC or another thermal option was checked off turn it back on. Putting the GPS to the moderate setting (the one below high accuracy) will keep the temps down as well. Are you using a custom ROM? If you're on Discord you can feel free to message me SCOPE★ BRΞΛD #8460 . I am only offering that so we can get this resolved quickly for you, just copy and paste since I use special characters.

Omgosh, thank you so much for taking the time to respond! Although I'm sure everything you are saying is very smart, I have absolutely no idea what you're saying. I'll do my best to try and answer you. I don't know what SCOPE is or how to send a message there. I don't think I'm using any thing for the "kernal". Also, I don't know what VCC or Discord is. As far as turning off setting for GPS or any other app, the phone will not stay on. I get about 1 sec after the logo when it boots up, then the error message about overheating and it immediately shuts off. I did a factory reset so everything should be good to go as far as apps. I don't think I'm using a custom ROM. The only thing I did was install TWRP, unlocked the bootloader and rooted the phone a year ago but nothing since then. As I stated earlier, this happened right after I did a display repair. Is there something on the MOBO that can get bumped that will make your phone get hot or send a overheating error. My phone doesn't show any sign that there was ever thermal paste on it prior but should I add some now. Will that help?

Update... Now the phone does not power on at all. When I plug it in to charge it I get an error that says "Device temperature is too high or low. Please move to another place to charge. I wonder where you went. I googled SCOPE so I could sign up to message you like you asked me to but nothing but definitions came up. I know I'm out of my league here. You guys all talk so technical. I didn't understand one thing the person asked me for. I know it's rare to get a response as quickly as I did and I was so happy to see someone had responded. Now, I just feel stupid and defeated. I thought this site was inexperienced with cell phones friendly. I'm just trying to get help so I don't have to go out and buy another phone again. Can someone refer me to a site that is more directed toward people who don't know much about the technical side of cell phones... please! Again, thank you for your time.

Hey, I just wanted to say sorry this happened to you. The same thing happened to me. My LG K20 Plus, no matter what button combinations I push and for how long I hold them, will not turn on or go into download mode. Plugging it in to a charger or PC does nothing either. Before it got to this state, I got the infamous green screen of death/Demigod crash handler (google this--it's a known issue with some models of LG phones and it happens when they overheat). It's definitely a hardware/build issue, and especially since this issue keeps the phone from turning on or connecting to a computer, I don't see a workable fix short of buying a new phone, unfortunately. Again, I'm in the same boat so I'm not happy about it either. I would say XDA is by far the best site to find a fix to this sort of problem, so if no one here has any suggestions on how to fix it, I think you (we) may be out of luck.

Thank you for letting me know. I'm not sure of some of what you said but I did catch the bottom line. Basically, just hold onto the phone until someone here comes up with a fix or workaround? I have a question for you. Did your problem start after you did some kind of repair? I'm wondering if I bumped something on the mobo to make it give a false overheating error. Do you happen to know where that sensor might be located? Sorry you are having problems to. It really stinks when your phone breaks and no matter how much time and energy you put it to figuring out the problem to fix it, there just isn't any good answers out there. I wish you lots of luck and if you figure anything out, please update here so I can try it too.

You need a whole new phone.
That or you're gonna have to replace the hardware
