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] URGENT HELP!!! My Screen isnt activating

Help ME!!!! Ive recently had my screen being unresponsive when i press the power/home button. its been about 2 days now and im struggling to get it to work at all now.. Is there anything is can do?!
The phone switches on and sometimes i get the screen to come on and as soon as i lock it i cant get it to come on.
I'm thinking its a dodgy connection to the battery. Its nothing to do with my rom etc. as i managed to restore back to Saturday before it started being faulty and its still the same...
Any knowledge is much muchly appreciated

Hey, I'm new to xda!
I'm having the same problem, my Xperia Play R800i will work for awhile after plugging it into the mains then when the screen goes into standby it won't turn back on!
I've tried a multitude of firmware and also tried relocking my bootloader.
Any suggestions?

Your flex cables have broken, these are the thin ribbon connections which connect from the motherboard to the screen itself. The Xplay has two flex cable. Best option is to send it warranty (2 years warranty) or you can buy a flex cable repair kit for the Xperia Play which will cost you around 30-40 bucks. There is an" Xperia Play Disassembly" guide on YouTube which should help you on the way.

Thanks for your reply!
I have had a look at the video and reseached a few replacements.
Would it be better to repair the ribbon connection with a kit or purchase another LCD screen?
The display does work sometimes and is fully functional when it's on. (I can reply to texts, make calls etc.)

OK, first of all you must consider if the phone has warranty as this is the free option you can go for. Are you in a country where there is a Sony Repair Centre? If you do not think you have the chance to acess a Sony Repair Centre then you only need the flex cable, the LCD digitizer seems fine to me, I think you have the same problem I had. You will need to buy something which comes with the tools to open up your phone.
Something similar to this.....

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

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

I think I destroyed my HTC One X

Hey guys,
I think I destroyed my HTC One X. I just bought it a month ago from Ebay, and it worked flawless. At some point the display just turn off. I restarted the phone, heard the sound when it starts and even the softkeys worked. But the Display was still off. After after a few restarts the display turned on for a minute, just to freeze after that and turned off again. The phone was still on though.
However I've read a bit around and found out that it could be a cpu heat problem, which could be true because my phone was way too warm sometimes. So I removed the display and put a tiny little bit thermal compound on the cpu. Somehow I managed to rip off the connection cable to the display ... also I managed to rip off the little black cable near the soft keys. The soft keys still work though.
When I start the phone the starting sound comes, the softkeys blink when I restart the phone, you hear the volume buttons etc. So it seems the phone is fully working. Just the display or touchscreen is damaged.
Some pictures:

So, what can I do?
Do you think I could just send it to this site http://www.directfix.com/product/REP-0063.html and let them repair it? Or did I destroyed my phone too much already?
Thanks in advance.

Well,the top cable is ripped off,you can't do anything at this point.The bottom one just seems out of slot as far as i can tell from the pics.
Basicaly you can send it to the repair shop,but i don't think that you can only change the cables,don't really know what to say...Could cost you some to repair it.

I don't want to only change the cables. I want to use this full repair service:
"HTC One X Complete Screen Replacement Service (Includes LCD & Digitizer)".
So they change the cables and put on a new LCD & Digitizer as far I understand.
But do you guys think they will put back the other cable back in slot too?

Please just answer, do you guys think they can repair it if they put on a new screen & digitalizer?

I don't see why not,you can also contact them and explain them the situation.Those cables are quite easy to put back with the proper tools so you don't have to worry about it.

[Q] [Panic] Ditigitizer problem or Motherboard?

This is my problem:
In may, I bought a Xperia Play on second-hand web from a guy on my city. In time, the phone got wet by rain, and digitizer started to go sometimes crazy, specially texting. I could survive with it.
After 2 months, the Ribbon Flex crashed, it showed screen completely screwed up, like in TV, you know, that problem that happen to everyone after sometime . So I changed it.
The point its, when i changed it, my old Digitizer stopped working ok, it gave too much problems. For 2 minutes it worked normally, except the base of the screen (that zone of the screen didnt detect my fingers, dont know why). Then, it wouldnt work totally, till, in some moments I took the phone, it would work for only minutes. I controlled the phone with the pad, but when it went out of battery by accident, I wasnt able to unlock again, as I couldnt touch and unlock the Pin code so I can use the phone again with the pad.
So I buyed a new one, which of course, I dont know why it doesnt work too (this replacement comes from a trusted dealer from my uncle electronics shop, so for the moment, I dont think the new digitizer itself its the problem).
What the hell Im supossed to do man? Im starting to go panic, because I dont know if the Motherboard have something to do with all this, and that means Phone dead right? Ive seem a lot of posts, all I could google with the same problem, and there is a lot of different cases and solutions with the damned Xperia Play, all starting with the damn unresponsive digitizer.
I saw the guide above amd i already posted there, but I wanted to leave a thread. Please, I need your help if its posible. Thank you at least for reading this.

Try replacing your flex cable again. Something like this happened to be, but the digitizer was completely unresponsive. After I replaced it, it works fine.
