d855 Touch not working; display not subjected to physical damage - G3 Q&A, Help & Troubleshooting

It's been exactly a year since i have first booted my phone up, and about a month and a half ago, the touch had started acting up, and soon, the middle horizontal strip had gone dead, and other regions followed, and now the touch is completely dead. I can't give it for warranty because, a, I live in India and the phone's from UAE, probably Dubai, and b, it would take a long time. I've heard that that's a digitizer issue. Does anyone know of a good seller for digitizers in a website like aliexpress? I mean just the digitizer. the whole display unit is too expensive and unnecessary. My display is still intact. No physical damage to screen whatsoever, except the one time I pressed really hard on the screen, after the problem had gotten worse(no cracks, but I did see the effect you get when you press on an lcd laptop screen on the phone when I pressed) .

Screen died?

Last night I was out and during the night I pulled my desire z out of my pocket to find that the screen was dead, the soft touch buttons were still lit up and working but no display. I pulled the battery and tried to reboot and no luck, you can hear it booting and even unlock/receive calls and txts etc once it has booted up just the screen stays blank the whole time so have to do everything on feel.
Essentially does this just mean my screen has a hardware fault? is it worth trying to fix? I assume the only option would be to purchase a replacement screen and dissemble and reassemble it?
(warranty is not worth it as I live in New Zealand and would have to send my phone back to the UK where I bought it from, also I have dropped it quite a few times so probably voided anyway...)
Thanks in advance for any input
Does it never display anything? So not even a flash during boot or something?
Because then it is probably a hardware problem.
Since the soft touch buttons do still work I think there might be a little crack or something in the flat cable that connects the bottom half with the top.
Maybe you could check whether you can see if the cable is broken or not?
The best thing to do then is to look for a replacement and try to fix it yourself or bring it to a shop where they can do it for you.
No it never displays anything, completely dead the whole time. The touch input is still working though as I answered a phone call this morning on it by making the usual gesture just without being able to see anything. Doesnt seem to be anything wrong with the cable itself as far as I can see. Yea might have to get someone to have a look at it.
My phone is acting the same. I dropped my phone in the pond before, but pulled battery out on time and had it in rice for a day. My phone was still working for about two weeks after that incident. I dropped it and had one little crack at the top of the screen and about a week after that it died when I had a water balloon fight with the phone in my pocket. D;
Do any of you know if the replacement lcd screen/digitizer for the Desire Z would work for the G2?
I had the same thing happening to my G2 screen, only it was intermittently working for a little while, then just completely died and wouldn't work. It was doing this crazy flickering thing then the back light wouldn't go on at all. If I held the phone at a certain angle in the sun, I could see that the pixels were indeed working on the display, but there was no backlight to make them normally visible.
So I purchased a replacement screen from ebay and carefully followed the directions on a youtube video for a G2 take apart. Its not a hard task to take apart and get down to the screen itself. It was rather easy. After putting it back together the screen still didn't work! Sounds work, i can also receive calls etc. But the screen still doesn't work!
Is there any way that this could be a software issue?
Oh and PS, I believe the LCD replacement would work for both the desire Z and the G2. They are identical phones after all right? I'd say its a safe bet. The screen I bought was only 35 bucks. Didn't think that was a bad deal.
Another dead screen or something else?
Few days ago my phone fell of the couch onto a rug - no big deal, so far it has survived much worse, but when I picked it up, the colors were all messed up - overly green and red. Tried restarting - no luck. Everything worked fine, except the colors, but then the screen turned of completely. I could hear notifications, phonecalls, but the screen was dead. After some tapping on the screen, it turned on again - with ****ed up colors. Then started flickering and was gone again. Few more times I could turn it on by tapping before it was dead for good.
Figured, after all these drops it survived, maybe the screen connector is a bit loose. I mean, I could sometime get a contact when tapping it, so I dissasambled it completely, secured all the connection, put it all back tougether and fired up - same thing: dead screen, phone working.
Has anyone had such problem before? Is it screen that is dead, or connector or... I have no clue... I would like try to fix it on my own, with some replacement parts I could get on ebay - but, what gave?

[Q] Just replaced digitizer and home button and left side of screen arent working

A customer brought her G2 on simple mobile to me with this problem: The letter "A" wont work on portrait mode nor will the home key. I figured it was the digitizer so I replaced that with an OEM Replacement part and as soon as we booted back up the problem was still there. Could it be her OS is corrupt or possibly a warp in the case thats keeping the plate from contacting the faceplate. I'm rather stumped as I ran a logcat and I saw nothing out of the ordinary during normal input. Any help is appreciated.
Touch plate? I am confused to what you mean by this. I am not too familiar with the electronic construction of a digitizer so any info would be helpful.
The digitizer isn't coming in contact with the face plate I believe. (Sorry I used like three different words to describe the same thing in my previous post) Any tips on how to fix that would be great. I saw a video on youtube that stated a part where a heat gun would be used but I never came across a front panel (The part with "T-mobile" on it so I installed the digitizer and went along). I think I may have messed up.
i have the same problem, i dropped the phone, and the touch screen was broken, i replaced it but now the left side and home button arent worksing
ps the broken screen worked still also on the left side , did you find a solution ?
I have the same problem.
I believe it's the ribbon cable, not the Digitizer. The ribbon cables on this phone hangs between both screens and is fairly exposed at times.
I still have a couple weeks in my warranty to return it to HTC, but I can't get it to S-on. Unless I get S-on before warranty is up, I'm going to have to replace it myself.
Ribbon cables for this phone cost ~$30 on ebay. tell me if you fix it.
Any luck with this, anyone?

Touch screen non-responsive in the middle

My Desire Z had a fall, and has developed two problems
1 - The hardware keypad has started to take hard-press and sometimes prints double characters on single press. I think the alignment is out or something... any other guess ?
2 - The touch screen sometimes stops working from an inch up from the bottom and continues to half an inch. Before and after that patch, the touch always works fine . Mostly, the whole touch screen works fine. But when the patch gets non-responsive, I have observed that by turning the screen off and on a couple of times makes it work again. I am not very sure what the problem is. Any clues ?
Thanks
I'm also experiencing a similar issue - for me it's usually an area that corresponds to the top row of the
on-screen keypad (for unlocking) or the top of the area for unlock patterns (portrait orientation).
Mine is a 2 year old DZ w. Cyanogenmod 7.1
No HW key problems & no droppage.
Liberal application of isopropyl alcohol and a microfiber cloth - especially around the edges of the screen
seem to help a little bit but not often enough to be better than random.
Switching the screen off and on occasionally helps but most often I get annoyed and use the HW keys to
unlock.
I have noticed that, after powering on the device, the SIM-lock keypad works just fine but the (different)
screen-unlock keypad fails. This leads me to believe it to be a software issue.

I have had this experience on my G2
No fix for me but his my experience check out the url!

Thread moved to Q & A section.
So i am going for Digitizer replacement will post the result when the phone is back.
And what about the Keypad taking hardpresses ? what can be the issue there ?
so my desire z is in the shop for repairs. lets see what problem is diagnosed.
I have read in another thread in this forum that the hardware keyboard (need to press hard on some buttons) issue can happen when the phone falls.
Apparently, the flat cable that connects the keyboard to the rest of the phone gets loose and causes such trouble.
Since your phone is in for repair, I'm sure this will get sorted when U get it back.
ok so my phone got back from repairs, the guy couldnt fix the touch-screen rather made it worse. Now the touchscreen doesnt work at all. So i cant unlock the phone and cannot test the Keyboard problem. The guy said the touch problem is related to the ribbon cable and not the touchscreen itself.
Note 1: He says he tried replacing the touch panel altogether but it didnt work.
Note 2: I still think the ribbon is fine (call it intuition)
Note 3: I am giving my phone for repairs again, but this time to HTC service center which would probably cost me a lot more than third-party repairs but at least it will get fixed.
I will update when I my phone back from HTC service center.
Could you not unlock the phone by opening the keyboard ?
It does smell to be an issue with flat (ribbon) cable to me as well. As if there was some loose contact before (caused by you dropping it), and after the repair guy took the phone apart, he probably made even bigger mess by ruining the flat cable completely.
From my experience (and I've claimed warranty 3x for the broken digitizer (touch panel)), if it's broken, an area of the screen (or the whole screen) will be permanently dead. It would not come back to life every now and then.
btw, mine always started being unresponsive in the very middle of the screen, a bar of height around 1 cm (somewhat less than 1/2 inch). Each time they replaced the digitizer.
If it;s the flat cable, you shouldn't end up being charged too much - those thingies are very cheap (in China) and the labour will probably be the majority of the price. Fingers crossed.
So I got my phone back again... The HTC repair center was not located in my city so I went to another (better known) repair shop. The guy said, "your phone hasnt been opened at all from the touchscreen side, any *repair guy* who claims he has opened it and tried this and that but couldnt fix is simply lying. This said, he opened up my desire z replaced its Touch Panel and voilah! my desire z is sensing again in 15 mins
What's the status for the keypad and need to press it hard to work ?
nope... I had it cleaned using alcohol / thinner. now it works fine.
So, I updated to CM 7.2 last night but the touchscreen problems are still there.
Updated using CWM and deleted data & cache whilst doing so.
I really hate the prospect of getting a new phone as the current models available
in DK are all without physical keyboards

[Q] LG G3 display not working

Upon power up flashes green then blue, no LG logo or anything else. If i plug USB connection to the PC the PC recognizes the phone any suggestions? By the way this happened after the phone was dropped, no visible signs of the screen being cracked.
Try holding power button for like 30 seconds. Or pull battery
Was this ever resolved? My friends phone did the exact same thing the other night, you can still feel it vibrate across the unlock pads and it makes noise and everything when receiving texts, can even answer calls if you know exactly where to push accept call.
It's the strangest thing.
Looks like a broken mainboard from the drop. Or perhaps cracked screen near the connection to the mainboard.
Not Resolved

Replaced the bazel/Screen/LCD, still same issue.
As I said: broken mainboard....
Same friend I was talking about earlier, exact same issue, he had his old phone he was using and just recently we found the issue, it had mild water damage from snow getting in his pocket right around the display connector inside, so we cleaned it up with alcohol, made some colors at the bottom but then would go black again, we took the logic board out, reflowed it in stages on each side so everything was good, tried it again, exactly half the screen (right side) worked perfect, so finally, brought it in, they said the display was faulty and replaced the phone under warranty.
So, conclusion, we didn't touch the display, Bell said the display was broken and just replaced his phone.
We only touched the logicboard and we got it half working, if we knew a better method of reflowing a mobile logic board (chips on both sides so you can't reflow the same way as laptop motherboard) so it was a lot harder but we probably could have fixed it if we kept at it and knew more about what size of the logic board needed the reflow the most
We used a bunch of clay if anyone is wondering, worked it in out hands till it was very plyable, make a pile slightly bigger then logic board, push board flat I to clay so it holds the underside chips pressed and in place, reflow top, repeat once cooled, it got half the screen working from a phone that had physical water damage and corrosion on the display connector so, this will probably work for you.

Touchscreen not working at all - phone is otherwise fine. What to do now?

Hi.
I would be really grateful for some advice.
I bought this phone (64GB version) in December 2019 (so out of warranty) and have been really pleased with it.
I scratched the screen, quite badly, about 3 months ago but it has been completely fine.
The phone was in pocket, when I was out in the rain the other day, and I noticed that the touch screen was completely unresponsive.
I tested the phone, with a mouse and an OTG USB cable, and it works completely fine - i.e. other than the touch screen not working, the phone is completely fine.
My question, now is what to do.
I have tried to dry the phone out for 48 hours (as recommended), but the screen will not work at all.
A few questions:
1. Is there any way I can check the phone for an error code in respect of the screen?
2. How much would it be to have a replacement screen replaced?
3. Is there a possibility that the screen is fine, but there is something on the phone's board that is in fact at fault?
4. Should I consider, economically, to just get a replacement instead - either the same phone or something else?

Check Developer options > Show Taps to know where the tap location of screen not working. If it has 'dead touch' partially or all of it, the digitizer or the touch layer is damaged. Mine was damaged at the right edge of screen where it did have a row of dead touch. I did replace mine. I recommend Screen + Frame package rather than screen only or even difficult touchscreen only.
It did cost $20 + $2.99 shipping on our online shop (Lazada, a Southeast Asian AliExpress affiliated online shop) for replacement of screen + its frame package. The risk is that it is not original screen anymore (not made by Xiaomi glass) and sometimes, it's a lottery to get working screen. You can do it yourself or assist it with your friend (or technician) who knows how to replace phone's screen.
