Display problem!! Please help! - G2 and Desire Z Q&A, Help & Troubleshooting

display does not always work. The phone is not rooted. So I don't use set cpu or anything like that. The problem that I am having is when I turn the phone on (after it is shut down) it does not display the htc logo, then when it gets to the g2 it does not display that either. When the finishes turning on the screen is still black. I can press the digitizer where I know the unlock is and I can feel it vibrate then when I unlock it I can still feel it vibrate when it unlocks and it takes about 2 to get the screen on from this just pressing the on and off power button. Some1 please help. PLEASE HELP!!! Any Ideas?

Sounds like a dead LCD unit. How/when did this start happening?

Dang so the lcd is not even turning on? Since your not rooted you should get a replacment phone

I searched other forums and seems like I am not the only one with this problem. All they suggested was to take out the battery, mem card, sim and leave it for a while and then put everything back in, the display was working fine again. Unfortunately, it didn't work for me, not even restoring factory default, not to mention going through that painful "shooting in dark" process.
I am already aware that if all things fail, LCD has to be replaced. Other than that if anyone has any other suggestion(s), it'd be much appreciated. Otherwise thanks anyways

I am going through same problem. Haven't found a 'non-LCD replacement' solution yet. Maybe the above will make things work for you. There was one guy who said he turned on the phone without the mem card. So you can try this as well.
If you find anything else, please share.
Good luck.

I didn't think it was a dead lcd because after about 2 minutes of the phone already running the lcd will turn on again. and I saw your thread that said to take everything out I did try that and it did not help. any other ideas?

Does the screen flicker? If you open it up halfway and gently nudge the flex cable, does it do anything?

I juat tried and it does not flicker at all. Once the screen in on there are no problems, its getting the screen on that's hard. Its realy weird. And it started about a week ago and the phone is out of warenty.

It doesn't sound like it should be a problem but I want to root it. And install a custom rom, and I am scrared to do that because when I boot into recovery I cant see the screen.

How can it be out of warranty? G2 wasn't released until October 2010 and HTC provides a 1 year defect warranty. Here is the link. http://www.htc.com/www/support/warranty.html. I didn't look at anything outside the US though.
This is not a caused by physical damage so should be covered??
Also, Tmo, if that's who you're with might just send you a new one?
I'm assuming you don't have the Asurion 5.99 plan? That would cover it for $130 last resort.
Oh, also, Visa or Mastercard will sometimes take care of you if you used it to purchase the phone so check with them in a pinch.

Blank screen, help!

Last night I pulled my Desire Z nam out of my pocket to find an all white screen. I pulled the battery and attempted to reboot. Upon reboot, all I got was a blank screen (the backlight comes on but nothing else) and it has remained like that since. As I didnt buy this through Bell or T-mobile, etc, I have no insurance or anything on it. Am I screwed?

I think your phone screen cracked... am not really sure but the best thing I guess is to find a repair shop

You are screwed. I had the same problem on mine. Put the phone down for one second. Picked it back up and it was blank. Rebooting and taking out the battery does nothing. I had to go to the t-mobile store and get it replaced as it was still under warranty. I am sorry for ur loss

Try bootloader? Take out battery, put it back, then holding volume down, press the power button.
If you can't even get into bootloader, I think you are pretty screwed.

I've having a similar situation with a black screen when I open it. Seems like the LCD is losing connection. Does sliding it open/closed have any effect?
Bootloader can be accessed but the screen is blank so its useless. Haptic feedback and backlight would still be there. But nothing else

Btw I'm in the same boat. bought a bell mobility phone on ebay unlocked @ full price, and using on at&t. Let us know if moving the lcd to a certain position helps.
something similar to this happened to my G2 and i JUST got off the phone with t-mobile about it. The guy said it was a known issue for the G2. Unfortunately, since you don't have insurance, your might have to spend some money... BUT i would first call HTC. I bought a G1 back in August 2009 of craigslist. after a year or so i was using it and the touch screen just stopped working when I opened my text messages. I called HTC and, for free, they took it in and sent me a new one. I believe its because the devices themselves have manufacturer warranty. So definately call them before you give up!
The screen stays blank no matter the position of it (opened or closed). I'll try giving htc a call but since its unlocked I think the warranty is most likely void. thanks for the replies

Screen flashes black

Hi, when i open my gamepad slightly my screen will flash black, and if i hold it in a certain positionbit will stay black until moved.
This also happens sometimes when picking up my phone
Is it a loose cable or something?
Should i get it replaced?
Rooted stock R800i, .42
Thanks
Probably the ribbon cable inside the slider. It's a known defective part.

So i could claim it on my warranty?
I got this problem too. But mine worse, sometimes when I wanna type a message the screen goes black, or the screen's light go like disco light, keep blinking at the home page and camera. I sent to Sony Centre to claim warranty but after few days they returned me and told me it was a software problem. Could this be kernel problem?
Yeah, sometimes just touching the screen can do it
I want to unroot before i cant see anything haha
Ive noticed that its just the backlight that goes off, if i make it go black and look at the screen in light i can still see the things there
Im going to request a replacement regardless, starting to annoy me
I tried to reinstall stock firmware but no use. Still the same. I'm gonna tear everything apart and take a look at the ribbon.

DO NOT I repeat, DO NOT take it apart!!
Once you do that your warranty is void permanently and no way to hide it! I can guarantee it's not your software. Revert it to absolute perfect stock and show them it still happens. I'm positive it's the hardware, NOT software.
If they don't wanna fix it after factory restoring, threaten to call head office about it because you already know it's hardware error and they are refusing.
And also mention that many people on the internet are aware that the slider cable is faulty, many have replaced it and fixed the same problem you have.
I'm thinking of mailing them, and requesting they have a recall because more and more people are having the same problem.

Ok, the screen only flashes black on SYSTEM APPS. The installed apps dont have this issue
Seems to have happened after i rooted
Any new ideas?
Okay. Thanks captain. I will follow your orders.
Ok, so ive tried to claim on my warrenty. They said they were gunna send a packet out to return the phone for repair. This was a few weeks ago. Within this time i have called them up 3 extra times stating i havnt recieved the pack.
Is this easy enough to fix myself as im bored of waiting for them and im doubting im ever going to recieve any repair

Touch Screen Problem on HTC Desire Z

Hi All
For the last couple of months my desire has had an intermittent problem with the touch screen. All of a sudden it decides you're trying to pull down the "notifications" screen when you're just touching the touch screen, sometimes it also decides you're trying to hold and drag when you're just tapping the screen, sometimes it simply stops responding. These problems are usually solved by tapping the top button and putting the phone on standby then tapping it again and waking it up - although sometimes it then won't let you drag down the screen unlock until you repeat the on/off standby procedure a couple of times. The problem varies on connecting my phone to my computer.
Given that in between these instances the touch screen works as normal I'm guessing it shouldn't be a hardware issue, but the intervals between these problems appear to be getting shorter (either that or I'm just getting more annoyed by it recently). I've had a quick search of the forums and haven't immediately found anyone having this precise problem. Is it likely a question of trying factory reset and if that fails sending it for repair?
Thanks in advance
Similar issues. Don't think this is hardware.

I'm having same problem, mine started couple weeks after I installed cm7.2, I tried another rom, no luck
Its definitely not software. I've tried froyo, gb stock with s-on and no root. I've been on ics roms cm7 roms but this problem occurs on all. I'm giving mine for service today.

Well since the OP didn't respond here's my suggestions. If you think it's software then just flash to a stock rom. You should find a number of them lying around the forums, and instructions on how to flash. This will mean your phone is unrooted and will need to be rooted, as well as taking care of installing a recovery and etc. This should correct anything wrong with the software.
Otherwise you busted the digitizer, which is actually very cheap to buy on Ebay. You will have to take the phone apart which can be time consuming.

Hello,
Any luck with the Tocuh Input, is your phone back from service? I am also facing the same issue....
I had this problem on my G2 a while back. It was a hardware problem so I ordered a new touchscreen and replaced it myself.

Hello Whiskey_Tango / Others,
Can you please let me know the details of the touchscreen component that you ordered for your G2? My HTC desire Z touch screen has also gone bad (unresponsive at multiple points) and I feel that changing the hardwre should do the trick.
If possible, let me know the touchscreen specs (model / part number) as well as any online website from where I can order it !
Many Thanks !!

Thanks for the quick response. Before coming here, I had a mobile service shop take a look at my handset and he had mentioned that for HTC desire z, the "touch screen" comes with the "display" attached to it. Did he meant the digitizer only or (digitzer + LCD screen) or he was simply trying to rip me off ?
I am very sure that there is nothing wrong with the display on my handset, its only the touch functionality that is not working properly.
Which one of the following do I need to search on EBay?
gultek.eu/htc-spare-parts/digitizer-touchpad/desire-z.html
or gultek.eu/genuine-parts/lcd-modules/htc/desire-z-hd3.html
or both?
Thanks again in advance !!
You need just the digitizer, if you're doing it yourself it takes about an hour if you've never done it before, don't buy the lcd if you don't see a flaw in it.
Some people sell the whole front chasis with lcd, digitizer, front bezel all connected for ease of replacement. May be easier but you will only shave of 30min tops and spend 3x as much

yeah this happens to my G2 a lot. I got my phone fixed a while back (2-3 months ago) becuase the colors on my screen were screwed up and the ear piece was broken. i took it in and he replaced a couple of cables. it worked fine but now sometimes the screen is just having a straight up seizure. it flips through pages so fast and it goes from page 1-2 and back and forth and then the virtual keyboard presses multiple keys and just its crazy. i feel like the guy that fixed my phone didnt plug in a cable all the way. but yeah thats my problem. i dropped my phone the other day and ever since my phone hasn't gone into a seizure lol
Hi, did you solve your problem? I have the same with my desire Z. It click alone in several place on my screen.
And I ask me if the problem don't come from the lcd digitizer control instead of the touch screen digitizer

Yes replacing the digitizer did fix my problem. And a year later the replaced digitizer started giving problems. So I ordered 2 extra digitizers off ebay. Both of them turned out to be duds. Surprisingly the second digitizer(which I replaced a year ago) fixed itself.
I think Im having the same problem,
bottom part of screen (including the home, menu, back, search buttons) aren't functioning half the time,
is there any service manual, or link to information as to what I need to tear apart on my DZ?
should this be enough? EBAYLINK
what do I need to replace the digitizer?

Phone boots, qwerty keys light up, but no display, soft key or LED illumination

I've searched the forums for a while and haven't found an issue exactly like this..
At first my phone would boot and the soft keys would light up and the LED would shine while charging. Shortly after that, I had no display and no illumination whatsoever on my screen. I just disassembled the phone to make sure all of the bands and connecters are connected and they are fine. I have reason to believe the screen works because when I receive a call, i can press where I usually would to accept calls and it works.
I have done some research on getting a new digitizer, screen, ribbons, etc.. but it's just too costly to justify it seems.
Any advice would be greatly appreciated

You can do that? Will they deny you if you're using a rooted phone or do you have to go back to stock first...

Depends on where you go and who you get. The last time I went, the associate thought it was awesome that I have sense on my phone. If possible, Odin back though.
I did get around to blindly putting my phone into download mode and flashing the stock tar through odin.. I'm assuming the flash worked since I heard the stock boot/shutdown animation theme music accordingly.
Unfortunately the screen and the soft keys are still not illuminated. The QWERTY remains functional including backlighting.
My phone is no longer on any network, but do you think I could still take it up to a location and bs my way into getting at least a used equal or lesser value device?
Put it up on Fleabay as a clean ESN, broken screen phone and stop wasting our time while you try to scam Sprint.

You're right, certainly not an ethical option. I'm more of a DIY person though, as I'm sure I could say the same for everyone else here.
Do you think it's the whole screen that needs to replaced? Ribbons and all? If so, do you know of a good source for me to purchase what I need

Don't do it. I bought my Epic for $80 and replacement screen costs $70. AND I'm in China where electronic products and accessories should be cheap.

HTC One Reset itself and is now stuck on Verizon splash screen

I have had my HTC One for 25 days now. I am not rooted and completely stock.. I was listening to Pandora at work with phone plugged into my work laptop. My phone reset itself and wouldn't go past the Verizon splash screen. Not wanting to lose my photos of my kids, I took the phone to a Verizon store and had them check it out.. they attempted a fast boot and asking them phones recovery which led to being stuck at the Verizon splash screen. Finally the tech factory reset my phone losing all of my photos and the phone made it to the lock screen only to reset when unlocking the lock screen and then freezing again at the Verizon logo on the splash screen. My phone also won't power off. It has been stuck on on the splash screen the past 5 hours. Verizon said there was nothing they could do in store.. anyone have any ideas on getting the pone back to normal? I've had zero problems prior to this and loved my phone thanks

They really sent you out of the store with a non-functioning phone? What the hell are you supposed to do? Call HTC?
Not that it helps you now, but create a Dropbox account or allow the auto-upload to Google. I don't want to risk being in a similar situation so I have my photos auto-upload when I'm on Wi-Fi to minimize the chance of something like that happening. Sorry man. I wish I had something to offer that might help.

Normally I have dropbox setup to auto save my photos, but I hadn't set it up on my HTC yet. The guys at Verizon kept trying to reset the phone, and finally, they were ready to have a phone sent to me tomorrow, but yeah I'm without a phone until tomorrow afternoon.. They said that the store doesn't handle replacement devices, and that a replacement has to be ordered. I decided to wait and go home and use my wife's S4 to call Verizon and HTC and see if there was any other way to get the photos off the phone, but unfortunately, no one at either tech support could figure out the issue with my phone and the Verizon rep at tech support says that since these phones are mass produced, sometimes things like this happen. I guess the point of my thread was to alert people of the importance of backing up your photos with this phone, and any other information of importance. Also, I'm excited to get my HTC one back tomorrow, the Verizon rep on the phone was also very nice and tried to request a brand new phone instead of a refurbished unit, but was unable to do so. He said that likely, due to the newness of the phone, that the phone may be brand new anyway. I guess I will find out after work tomorrow. Hopefully I get a nice new One tomorrow, and the first thing I will be doing is turning on the auto-upload feature and the Dropbox sync.
That stinks, sorry to hear that happened. Let us know how it turns out, and whether you got a refurb or not.
That's definitely a con to this phone. In some situations, a battery pull can relieve problems sometimes.
Got a refurbished HTC one from Verizon disappointed its not new. Slight gap near the power button but nothing too bad seems to be working great so far.

damn I was hoping we'd get refurb phones from HTC, I don't think I want Verizon taking apart this phone personally.
Idk as long as it's put back as well as the first, no complaints here.
I'd jsut send it back until one came that is perfect.
I've sent back I think it was 4-5 htc rezounds refubs before I got a good one.
damn, refurbs already? That didn't take long.

just hold power for ten seconds.. or power and volume down.
easier than a battery pull, IMHO.
Just keep calm .
So i recently forced mu htc to get stuck at verizon with xposed module.
And got a working solution, as the phone gets stuck just run:
1. adb shell am start -a android.intent.action.DELETE -d package:com.package name
2. adb shell pm uninstall -k com.package name
witch the package would be the latest apk you have installed it, it will give you errors cant not find or access.
just let is go on and then it goes ON worked for me.
Hope it works fir the next guy with the same problem.
Xposed puts a flashable disabler zip on your sdcard (Exposed_Disabler_Recovery.zip). All you have to do is boot into recovery and flash it. That will dissable the exposed framework, and all related apps.
