Pressue on LCD and now it doesnt show anything - G2 and Desire Z General

Everyone makes a mistake and I did one that wasnt too good. I had pressure on my HTC Desire Z. I was at a lan and I slept with it in my pocket. Next morning the alarm went and I want to shut the alarm off but the screen didnt wake up!
Rebooted the phone and still dont see anything but when I turned the LCD on, I could see a few lines and the LCD was lit up but nothing showing. The dignitizer still works due to it reacts when I unlock it.
Anyone have any idea to fix this? Is it really only replace the LCD or there is no small fix?

hit up ebay and look for a lcd + digitizer.. it's the simplest way of fixing your problem.

I think you need to buy a new one, don't sure but if this keep long may harm your device

LCD working but no backlight

Thought I'd try talking whilst going for a jog and managed to get some sweat into my XDA Mini. The result: the LCD still operates, but the backlight is broken.
I took it to a repair shop to see if they could repair it but they say I need a full new LCD - not so cheap. The guy seemed a bit dodgy so I thought I'd double check people's thoughts here before I go and spend the $150 to fix it.
I'm sorry if I'm insulting your intelligence, but have you tried holding down the power button while the screen is on? The backlight can be toggled on and off by holding the power button down a few seconds.
Just making sure!
(Eg. Check your floppy drive before you decide that the hard disk is dead - store attendants can actually forget things like that)
Haha,
Yes I have tried everything relating to normal backlight usage, including a hard reset.
I know the backlight is stuffed because for a while it would turn on for a sec before turning off, then finally it went kaput.
Well the backlight probably is stuffed. And $150 is a bit steep for a new screen, but I doubt you will find any better - though if you want try eBay. I just searched eBay US for 'xda mini LCD' and got a range of LCDs from $70 to $100.
The installation isn't too hard, as long as you're careful - it just involves opening the Magician (which takes patience, but isn't too hard or risky), unplugging the old screen, detaching it, and installing the new screen.
Darn,
I found a screen for AUS$115 delivered on ebay.
Is there any way I can tell if I have the black or yellow screen connector without opening the phone up (I'd prefer to have to open it as few times as possible). My guess is that it would be one of the black ones as I think it's an earlier model.
Hey maximus, I know it's been a while. Did you fix your screen? I've got a Trinity with me (also known as Dopod D810) and I put a new screen into it. It worked, but after a few weeks, the alignment went off and would not reconfigure no matter what I tried. Then suddenly, the backlight went dead but the LCD still worked (I can see the content on the screen if I shine a torch on it). I'm an experienced phone repairer but I thought I'd check to see if you did anything to fix your original screen.
I've got the phone open - the connectors are fine. I've tried applying light pressure to the sides of the LCD, hoping that maybe it was just a loose connection inside the LCD, but to no avail.
Looks like I'll have to buy another LCD
hey i'm have=ing the same problem !
there are not any option but new screen

HELP> Flashed Desire Rom, now screen wont light up

I have a serious problem. I noticed a bug in the Desire alphas where sometimes when the backlight went off during a call it would not come back on when the i took the phone away from my face. It always came back on eventually.
Ok now yesterday I flash alpha 8 and it worked fine. Now all of a sudden I reboot my phone bc the battery dies and the backlight won't come on at all! I know the phone is on because the haptic feedback and cap buttons are on and if I leave it on I can tell it's getting notifications.
How am I supposed to fix this?! I can't even see anything to get into recovery! My phone is unusable.
Find out every step to do a backup in recovery... see if that works

Load into bootloader
Press power button once and wait about 20 seconds
press volume down once then hit power button once
Wait about a minute and move the trackball down slowly 3 time and press it
Scroll it down once and press it four times

Unless your screen is broken you can always boot into recovery.
Take out the battery, then put it back in.
Hold the trackball down as you power on, this will boot you into fast boot.
Select bootloader, then select recovery. and bam your in recovery and can reflash.
I can get my phone into recovery. When I adb in i can push the phone into recovery, then when i hit adb devices it shows my phone and says recovery.
the problem is the backlight is not on even when i am in recovery. i would say the screen broke, but it seemed like a software problem, because it was just slow to come back on. It still always came back on. then I left it in my car chargine and it never came on again. The phone seems to be working fine though.
Kind of off topic, but did your call screen do this before flashing to Desire at all? Did you recently install a screen protector? I had problems with the PhantomSkinz screen protector making the proximity sensor less sensitive and behaved exactly how you're describing...as soon as I took it off it started working again. I'm now using a dcmugen88 screen protector and it works great.
interesting. i have one of those bodyglove or whatever protectors. best buy glued it onto my lcd. i suppose it could have started around that time. but would the proximity sensor still be deactivating the lcd even when its booting up or in recovery?
Oh, I must have overlooked that. The screen protector wouldn't cause any issues on startup or in recovery... guess it must be the rom then.
well, figured it out.
warning to n1 users: watch that lcd screen under the glass. its not nearly as sturdy as the glass cover.
the lcd/digitizer screen under my glass got cracked and stopped working. no drop, no warning, no funny colors. htc does not cover this in the warranty no matter how good the actual phones condition is.
i almost didnt get another n1, a phone thats inherantly weak (i found dozens of similar reports over the web) is not exactly a good case for a system with no insurance, no store to walk into, and very unhelpful support. they try to be very nice, but the rep i talked to couldnt even tell me whats covered and not. he just said let us charge 500 bucks to your card and we will ship a replacement, then decide if we think you have to buy it once we get your old phone. i demanded to talk to someone who did know. his manager denied hearing about lcd screen problems... after the original rep said he and htc knew this was a common problem. google didnt even return my email when i first contacted them saying my backlight was broken.
so again, be careful and get a good case.

hd2 dark screen

i got a crash i resetted ther phone .
after that phone works but the screen stays verry dark.
as if the backlight is broken.
i can see verry little on screen since its just so dark.
phoen works i can get phone cals etc but i just cant see a thing.
whats the problem . is my screen broken ?
please explain the word "crash".
did it fell down or did just windows crash?
if windows crashed and it didnt fall down, you can call htc or go to the shop where you bought it.
DN41
i got an sms .
then phone stopped working .
the touch screen didnt work anymore and i had to take the battery out.
i put it back in and turned on phone.
phone worked but screen stayed dark , i can see something things on screen but its verry dark.
now i put it on the charger and battery was goin empty verry fast even thoug it was on the charger it didnt seem to recharge .
while in the charger the phone was getting verry hot also . so i cant do a thing now .
edit .
im thinking isnt it just possible that since the battery looks dead, that the screen just isnt getting enough power to be lighter ?
since both problems came at the same time i guess they must be connected in some way .
i mean is it possible that a new battery solves the problem or isnt it worht ordering a new battery ?
CRashed ...from a window
My phone crashed too... Crashed onto a carpetted floor from a window (about 5 feet) while being charged, and landed on the edge of a barbell. What was it doing there u ask? I wanted to get the best 3g reception thats why. I use it as my main modem/router y'see...
Yes i got a really dark screen too, and two vertical bright lights. the screen was alright, no cracks, nothing. but the buttons was dented since it landed on the barbell(which was on the floor ).
Sent to the shop and told me it'll cost me about 170usd to fix the lcd,..and said it's gonna cost another 50 usd to fix the touch screen. Knowing the shop was b.s'ing since i know the lcd could just be the only one affected so i plan to buy just the lcd. did a few practice disassembly, and eventually after the 3rd disassembly and reassembly the screen was completely dark...even if it did lit up, i cant see any image.. so i guess i'll just get the lcd+touch screen. since i dont wanna go through the hassle of soldering the fine connection anyway, i decided to buy the lcd+touchscreen online cositng about 140usd..
well, obviously mine's a hardware problem.. Buy yeah I'd say that the hd2 is sooooooooo fragile, your hd2 problem might be mainboard related.
ps. still waiting for my replacement lcd+touch.. who knows if mine is motherboard related too(since the buttons get hot, but i can still recieve calls+use as a modem)

if you can see the screen at all, you might check your backlight settings to make sure they didn't reset to like 10%.
Otherwise, I would take it in to get fixed. Sounds like the backlight died.
Have you hard reset to make sure it isn't a software issue?

odd backlight issue

I have a odd backlight issue going on with my G1 i took some pic and now the backlight won't come on no matter what setting I choose, if i slide open the screen and tap the backlight setting it comes on but it won't with the screen closed any thoughts? oh and when i open the screen I have to change the backlight setting in order for it come on
Question and hopefully someone has an idea could this be hardware and here is why I ask if I turn off the phone the backlight doesn't comeon at boot if i open the screen and boot the phone it does.
I am stuck and hate to set and dismantle the phone for no reason
did you drop it? a lot? lol not sure why that would happen unless the rom has a bug in it... what rom are you flashing? or is it stock tmobile firmware?
to be honest I don't remeber which rom I flashed it about a yr ago it has been working fine since I decided to dismantle the phone to check the ribbon cables as I noticed if i open the screen just a bit the screen works. however they were fine does anyone know how the screen switch on the G1 works i was thinking maybe it may be the problem as while i had it open I put power to it and played with the ribbon cable and it had no effect but moving the screen did.
Thanks,
yonu
P.S. sorry for long post
hmm. maybe a wire or sensor got unplugged or moved when you dismantled it... with out seeing it i cant really think of what could be the issue... i kno you tube has 100's of videos on taking apart the g1 lol maybe see if you skipped a step...?
Nope didn't skip a step I simply was hoping tat someone knew how the screen switch worked so I could try bypassing it as I think it is my problem

Black Screen But Phone Is Still Working??

Hey guys
Just bought my moto x play. And on the same day it screwed on me. So after i got the phone i updated to Marshmallow, And left it in my room to charge. On my way back I realized my phone was not turning on. I turned it off and turned it back on but nothing happened. I only felt the vibration of the phone and seeing the screen light up black pixels (no idea what the proper term is)?
I can still use the camera with the twist gesture and i can still hear the phone taking photos when i click the volume rocker. But the screen is black and i cannot ue touchscreen to take phtos. I also noticed that the LCD lights up black again if i lift my phone up. Just like moto display would do with notifications. I also hear notifications on my phone but nothing else. I have serached for a fix but nothing anyone else have this porblem?

Most likely it's a hardware issue.Are you able boot into bootloader mode with screen working?
boot into recovery and factory wipe it.

I faced similar issue with my previous droid maxx, phone was on but only the screen's backlight came up. It happened all of the sudden when I was watching youtube. I thought the LCD ribbon connection was loose so I disassembled the whole phone and put it back on but no success. I ended up leaving it on the desk and one day the screen woke up on its own. The battery was at 1%, not sure if that triggered anything that fixed the problem. Maybe you could leave the phone until it drains out the battery and see if it could work for you.
Another way is to get into fastboot or recovery and do a factory reset
Maybe the flex cable is loose or disconnected
Assuming you haven't unlocked the bootloader,ask for replacement.

Yea I am. I have to wait until Monday for a reply
Hi Danny_Cai. I'm currently experiencing the same issue with my Moto Z play smartphone. So I wanted to ask, did you just replaced the phone in the store? And what was an actual cause of this problem?
Possible solution Motorola X-Play Back light Problem
Hi Danny,
I had a similar problem with my phone. Not under warranty so took the back cover off using a T3 star bit.
Radio Shack probably has it also.

At the bottom of my phone, there are two spring contacts. One was sitting loose and must have been causing some kind of problem. It fell out, and I did not reattach it. Haven't had a problem since.

It may be something as small as that. Not sure what it was for but haven't noticed any difference in the phone.
Hope you find your solution.

Guys i also have this issue, did u figured it out what exactly it is?
