[Q] [Hardware] LCD Problem, Looking for advise. - G2 and Desire Z Q&A, Help & Troubleshooting

Hello just wondering if anyone else his having this problem or heard of anything similar just looking for advise before I approach the phone company.
(Im in the British Military away on OPs atm so need to try and describe the fault, and hopefully get a good will replacement without the U/S phone sending back)
So anyways My LCD when open to a certain degree and sometimes when not open the screen Inverts. It also sometimes Freezes this happened before root as well as after so it isnt a software problem more of a hardware, It happens sometimes fully open sometimes certain degrees open and sometimes totally shut.
However if you move the screen around it will return to its normal condition which leads to me believing its not the LCD screen itself but that little cable that transfers Screen to phone hardware.
Just wondering If anyone can give me a confirmation? and perhaps some technical Jargon so I can pin point it down in my email. Any help is appreciated
Cheers!

If its the cable that is the problem u can just swap it.
The keyboard/housing/ribbons are 59dollar on ebay.

Thats the problem im looking for ideas whether that might be the problem whether anyone has experienced it before. Im really remote in choices of what to do atm due to my circumstances so I was looking for whether anyone might identify this as the same as another fault they have had previously or a "common wear and tear" sort of fault if you know what i mean.
I do appreciate however without eyes on the devise that is very hard to do.

Can you try and open the keyboard halfway then try to touch the cable with somekind of stick? And see if your screen messes up or not?
If it does mess up its possible that ur cable is damaged and causing problems.
Just wondering. Are you running custom rom? I know ur phone is rooted but u didn't say ur running custom rom or not.

[Q] desire screen acting weird

I just got a desire (used) and the screen is sometimes unresponsive. Every few times, if i touch it, the screen like goes left and right and studders up and down and isnt responsive to any touches unless you reset the phone, or turn the screen off and on a few times.
Then i try to press something, it do another thing and etc. Also phone is heating alot and i think something is wrong.. or maybe i should try to reinstall fw?
Anyone...?
Mine does this screen thing on some rare occasions, the only solution is a reboot.

For me its very often. Im just curious what might.be causing this problem. Can it be hardware or software...

Sounds like a hardware fault.
I don't know if you have warranty since you got the phone second hand, but if you have, you better send it.
You can of course do a hard reset first, just to be sure it's a hardware issue.
settings>sd&phone storage>factory data reset
I have already done hard reset when i bought it..but its the same. So i dont have warranty.what hardware part might be causing this?cause maybe i could still repair it?

Better send it in. It's extremely difficult to replace components on the desire. Even service people do a crappy job of it sometimes.

[Q] Desire Broken display?

Hi guys, I have a problem with my Desire, but cannot find anyting about that kind of problem in xda-developers or internet.
Here is the video with the strange effect http://www.youtube.com/watch?v=XRqpW-pRNWI
The problem is that it occurs at random times.
Have you ever seen that kind of problem, is it the display or the motherboard?
No and prob to do with the connection most likely. Send it to HTC.
Wow, thats heavy, did you try to reflash whole android? It kinda seems to be a sw fault. But if you have, then another question would be if you have dropped the phone, if yes, prepare yourself cca 85£ if not, then warranty should apply...
Anyway, you will need to send it for repair

No its not droped. I play very nicely with this device, it is "Desire" after all.
I tried the original rom, the efect is the same. This happens even at bootloader.
I have a doubt that the phone was not brand new when I received it with missing foil. The phone was purchased from internet from local store.
This was happened a few week ago, after it was returned from service they said that the display is twisted
Now the probleam apears again.
Anyway, now the display is completely dead - i see only black screen with slim lines with different colors. Tomorow I'll visit the store again, but I don't know how to prove that it's not my fault.
That might be dificult, keep your receipt and in case shop refuses to fix it in warranty, then Id go directly to HTC hoping it wasnt opened and tampered with...

One X Dead

hey guys,
so my friend got a One X, that's Dead...pretty cheap...and we're trying to revive it.
up till now, the phone only vibrates when pressing the power button, screen doesn't wake up. how to access the bootloader "if it's even accessible"?
any way to know if it's fixable?
Uhh, it doesn't sound too easily fixable. If the screen isn't even turning on, you're off to a bad start. Sounds like some kind of hardware fault, not something you'll be able to flash to fix.

That's a hardware fault maybe faulty flex cable

if you look at the phone, it's very clean, i can tell it never had a smudge or any fall...also the screen is clean, no scratches. quite a catch! what could have made the flex cable go bad?!
in the boot animation the screen is quite good!
You say in the boot animation the screen is good, does it ever clear up entirely? You COULD get a display like that from software, but it's more than likely hardware. For example, running Gingerbread ROMs on the Infuse with Froyo bootloaders cause similar rainbow effects due to a change in coding, so you can POSSIBLY have a scrambled display without a hardware failure.
It may have just been a faulty phone and that's why it looks like it's in good shape. It's not necessarily something that someone broke. It could be a bad GPU chip, it could be a flex cable as mentioned, it could be a lot of things. If you (or rather your friend) got it for cheap, and you want to try opening it up to inspect the cables, you can find disassembly threads and videos to tell you how. You could be going on a wild goose chase though.

sometimes it boots up with that white messed up screen, sometimes it boots with the sense 4 lockscreen. lags a lot while trying to unlock the lockscreen, after that all hell breaks loose and screen becomes messed up pretty bad.
thanks for the tips man, i will try opening it up and having a look inside.
it could be a bad factory outlet as a friend suggested...

Well, hell, you can try reflashing the software if you can see enough in recovery mode (vol down and power at the same time). I can't see how it would hurt it any more. From the sound of it, you either have VERY messed up software, or more than likely, faulty hardware. Does it seem like the display works any better when it's been off for a while (cold)? If it gets worse the longer it's on, or if it had been on and you just rebooted, it would point more towards a faulty gpu chip to me and the heat causing the problem to come out.
Not sure about how warranties transfer or if they do at all (might depend country to country too), but you could see if it's still under warranty and can be sent in before you open it up.

Hmm... weird. Not sure what to say. Well, good luck. I hope it works out!
What honestly it looks like to me is that they tried to flash a american version of a rom on to the phone so you have the improper bootloaders and such. hopefully this works for you.

I know I don't own an one x, but I do have a HTC Rezound, and I cracked the screen in it, and mine did the something while watching YouTube videos, but then it just went back to normal, this happened twice to me. I thought my screen was going out, but if yours is doing it and there's no physical damage, had to be something in the phone, or maybe software is that even possible? Lol.
Just thought I'd share what happened to me..

yes it could be a software issue. so your phone had that issue after changing your digitizer/screen? and then became normally by itself later on...?

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 !!

Be careful to get the one for the vision not for the magic

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?

Digitiser non-reponsive, need to root.

Okay, I haven't actually used this phone in ages, over a year, but a friend of mine is long-suffering with a BlackBerry and I feel obliged to end her suffering. There are two problems:
1) She wants Sense 4.0.
2) The digitiser is smashed and non-responsive. (A replacement has been ordered)
Now, I am sure that there is a few Sense 4.0 ROMs lying around here due to the fact that HTC released the Desire C, which has the same resolution screen.
So, I started to go through the process of unlocking bootloader, flashing recovery etc and fell at the first hurdle. When I had this, I didn't even look at the developer options, which seems to have screwed me over, because USB bugging is disabled.
So, basically, does anybody know how to enable USB debugging without actually using the screen? Or anything that could enable me to get all of this done now, so I can just replace the screen when I get it and give her the phone?
Nope. Gotta have the screen! And there's not a single sense 4 rom and there never will be. Desire C is armv7 the WFS is only armv6; it's not a case of screen size, but processor compatibility

Ouch.
Indeed, you're going to have to fix the screen first.
I faced a similar problem some time ago. Unfortunately, the digitizer has to be fixed first
Alrighty then. I've seen many reviews saying the far right side of the screen often does not respond on replacement, is this true? I was looking at one on Amazon, although the seller is "HTC" I don't buy that for a second.

I'm very curious on how you proceed on this. I got the same phone and exchanged a non-responsive (shattered) digitizer to a new one which also seems like it is totally unresponsive.
I have read that you need to go into diag mode and calibrate the phone after exchanging digitizer, which seems impossible without USB debugging is set to ON. Unfortunately mine is set to OFF and I'm stuck with an unresponsive digitizer...
Did you get it to work?
