MY HTC desire Z G2 screen is Blank - G2 and Desire Z General

I woke up and received a call and 10mins later,the screen of my phone went blank,the phone works perfectly,still receives calls on it,but i don't know if the LCD screen is out..never fell down,just confused right now..What do you guys think might be wrong??
All ideas are welcome..
Thanks

Same happen to me. Mines turned out to be the led ribbon was lose. Took the phone apart and reconnected it and all is good. But also my phone has fell off the bed a few times so I'm guessing that's why it came lose.

Its a strain to read that crap... use real words spelled out correctly.
You probably pulled out the ribbon cable from the back of the screen.

Hello good sirs,
I am unsure as to what has happened, but my G2 screen has gone black. The phone still turns on, and i can hear it make noise but the screen will not come back on. The phone is rooted, but it was working fine until the battery died. Have any of you fine gentlemen experienced this issue?
There fixed
Lol

I had my battery die completly on me once. After i pluged it in, it acted as if bricked. No lights, no power, nothing. So i pulled the battery for 5-10 mins and then it worked again.
The phone doesn't charge while its booting up. Therefor if you let it die completely then plug it in it has to charge for a couple minutes before it can boot up again.

Dropped my desire hd

So, today I dropped my dhd.... literally 3 feet, nothing crazy..... and it has a full body invisible shield and an otterbox case.... it did land on a corner, wood floor.... now, when I go to wake the phone up.... it turns on. It is randomly powering off since the very, gentle fall.....
It does not make a lot of sense, any thoughts or recommendations appreciated.

try taking out your cards and battery, the drop may have un seated them
first thing I tried.... clips look good, battery looks good, phone looks great.... when I put in my second battery... it seemed to be running well, until 6 minutes ago, when I pressed the power button... silly phone was off again.
I powered down, ejected all 3 items, placed them all back in.... it was such a harmless fall, with a full protected phone....
sounds like something may have become loose, i sense a rma back to htc if a full wipe etc dosnt solve it
not 100% sure, but after pushing the sim card out and in again... has not happened since.... I hope as heck it is ok, such a simple drop, heh!
thx
I'ved dropped my phone like a thousand times but nothing like this has happend too me!
I think HTC will replace on you warranty for this... Ask them!
sim card not making connections properlly will cause the phone to reboot, as i found out when i first got my desire hd, my 15 year old simcard was too worn to make a clean connection. once i went down to the tmobile shop they descovered it was that at fault after i said the phone was knackard.
simcards will compress very slightly over its life causing poorer connections.
if the problem has now dissapeared it may be worth your while getting a new sim if it is of age.
Hi audiobookman
15 year old simcard

Yep, t-mobile has always been good to me (actually the card was 121 printed on it).
Hello guys,
Funny thing, I gave my dad a DHD to play around with (hoping that he will finally get rid of his BB), just a few days ago in his office he mistakingly dropped it 7 floors down to the parking lot.
Amazing, just amazing, except a few bumps here and there, a cracked Sim cover and a bit broken battery cover, the DHD came back to working without and problem.
I am sure if it did not happen to me I would have been sceptic, but IT REALLY HAPPENED.
Thumbs up htc for a strong unit.
I dropped mine from my pocket and nothing happened, not even a scratch.
I'm gonna report an incident I've reported again in the forums.
When I first got my DHD,about one week if I remember well,I went for a drink with some friends.Before we went to the pub we usually go to,we wanted to eat something,so we went to this fast food.While we were waiting for our food,we were saying the usual bull**** we always say with the guys.Sometimes though we tend to pull the strings,and I told one of them off badly,so he decided to punch my leg.Unfortunately,with his full strength,his fist landed on my new,shiny and unprotected DHD,which was in my pocket.As soon as I realised it,my heart went at the kidney's place,the kidney went at my stomach's place and my stomach went all the way to my head out fear!
Next day?My DHD was like nothing happened and my pal's hand was almost broken.
Yep,thumbs up HTC!
yea, it was pretty weird and once in a while... I hit the power button and it is OFF again, not rebooting... off, hitting the wake button turns it back on.... might be software etc....
but on that day, it was happening every 2o minutes, lol
I love htcs design.

Grey Screen (NO REACTION) - Please help me out guys

Hey guys...
So, I have my Desire Z since about 4 weeks and nothing went wrong with it.
Really NOTHING bad happened, it didn't fall on the floor, didn't fall into water, etc etc.
So this afternoon I unlocked it and suddenly I got a blank grey screen.(worked perfect in the morning) The phone did react to my power up/on button, but I couldn't see what I was doing. Also the touchscreen worked, because I could unlock it (I heard the unlock noise) but I only get a blank grey screen.
I tried Bootloader and Battery pull. Also I took out my SD/SIM/Battery and just blow through the whole phone but nothing want to happen:-(
By the way, my phone is fully rooted and running on Cyanogenmod7 since 5 days. Everything worked perfect until this afternoon...
EDIT:
Looks just like this http://i51.photobucket.com/albums/f368/forthcomingtangent/DSCI1196.jpg
C'mon guys:-(
So is it grey from bootup till it gets to the rom or can you see your boot splash screen and whatnot?

Yes, when I boot it up it's grey, I notice that it's still working because I get the bootup noise. So I can see nothing. But what I noticed is that the grey screen gets a kinda bluegrey screen while the cyanogenmod7 boot animation(the loop)
Sounds like a hardware issue to me, I'd send it in for warranty if I could. Plus, with your screen being the issue I doubt they would check for something like S-off or anything like that
sounds to me like the ribbon cable for the screen has either broken or not placed in its socket properly, does it make a difference when the keyboard is open? try opening it and closing it a few times... watch the screen. otherwise it could be a fault with the screen board or the screen itself
i would try and claim off warrenty or insurance
No it does no difference when the keybaord is open:-(
Problem at the whole thing is, that I have no warranty because I bought it at amazon.com
you either have to see how much htc will charge to repair it, or take it apart yourself and just check the cables... if any are loose then refit them... or buy a new screen, vga board and ribbon cable and fit it
How much would the last option cost?
And how much do you guys think HTC will chare to repair it?
http://cgi.ebay.co.uk/OEM-SLIDE-FLE...944?pt=LH_DefaultDomain_0&hash=item2a10708cb8
something like that if its the ribbon cable.... but that gives you the whole kit
http://cgi.ebay.co.uk/Touch-Screen-...K_Replacement_Parts_Tools&hash=item2a0fd454a5
thats the digitizer but i dont think youll need that but just in case
http://cgi.ebay.co.uk/NEW-GENUINE-H...K_Replacement_Parts_Tools&hash=item2eb3f529d0
thats the screen
but in fairness your better off taking it to a repair shop and getting a price... if you havnt got a warrenty then you dont have to worry about loosing one
Wow thanks, you're really helping me.
So I found a warranty document, since I bought it over amazon.com from another seller(mobilejoker) and it says that they'll repair me my device if it is defect and not my fault. But they also charge 40$ if it's an obvious damage made by myself. Well, I don't know, it wasn't my fault right? I mean it's not like it dropped in water or fell on the floor.
looks to me like its the ribbon cable or the vga board for the screen, as long as you havnt dropped it in liquid, on the ground or opened it up then it cant be your fault... id go with the warrenty first before you open it up
Hit the thanks button please matey
Done
And thanks again for your help.
alrite glad i could help, if you get stuck or if the warrenty doesnt work come back
hey guys I'm having a very similar issue on my phone, I bought a screen on ebay from a USA seller, as well as a flex cable cus both were damaged in my phone. I've got both of those installed and the phone boots up, gives off noises and vibrates like his did, but no video. Backlight lights up, but just black. I've been googling a lot and apparently the grey screen is just a precursor to what I have. Where exactly is the VGA board? is it on the main logic board? does it need a reflow like some laptop chipsets?
Hey guys I just thought I give you a quick update.
So I got my device back, it's working perfect and I didn't have to pay anything for it.
I'm just a bit confused, because my phone now is totally unrooted, and I always thought that root hurts your warranty.
Anyways, thanks for your help!!

Either they gave you a new phone or...
They replaced the screen (or samaged parts) and wiped or perhaps upgraded to newest stock.
Do you still have all your info and apps that were previously on it?
What version of android does it show in about, and which hboot do you have now?

Well it's just like it was when I bought it, 2.2.1, only google apps, had to configure sim again no sms, etc.. But my phone is definitely now new because there are my scratches on the back of the phone.

I didn't quite understand your reply, lol sry, but I did see one big clue....2.2.1. Which means you should have no problems rooting again.

I don't have any problems with rooting again, I was just saying that I was confused that I got my device repaired for free, although they unrooted my phone.

u8800 is a very sturdy phone :D

I dropped my phone to ****ty water where it stayed for 5 hours... after that it went to police station where it was 2 days wet in a minigrip bag. After that i washed my phone, blowed it dry with hair dryer. For few weeks my vibration did not work but starded working. Second problem was GPS that did not work. But today it started working. Just wanted to share this info with you. Great phone.
Lucky man my luck it would all be stuff
I can't really agree:
I got in a really terrible rain with my X5 in my trouser pocket, I got soaked. Back in the car I took the battery out of the phone and dried it as best as I could.
At home I removed the SIM card and the SD card and let the phone dry for a week.
It's been two weeks now, the phone starts up, but you can't slide the unlock slider all the way to the right - it looks like the touchscreen isn't working in the rightmost 1 or 1,5 cm of the screen.
Also you can still see a few faint stains under the touchscreen.
I hope I will not have to test it but it is nice to know that a few drops will not harm it..
By the way (excuse me if I'm hijacking the thread) are those screen protectors that use a liquid "solution" in order to apply safe (enter the phone throught the speaker mic etc)?

Screen flickering problem

Temp fix on post 7
Hey, I've owned my phone for
about 6 months. It has been fine till about a week ago when I flashed a miui rom (Mintberry). At first, it was just occasional flickering, everyday or two for a few seconds, but now it's turned into a fair bit more.
If I don't use my phone heavily for about 3 hours, and go back to the phone, the screen has turned completely grey. When this happens, no matter what state my phone is in the screen flickers. It generally begins flickering very fast then after 5 seconds the screen is completely grey (even once rebooted).
I have dropped my phone a few times like everyone does, nothing severe or even close though. I didn't drop it then have it instantly happen.
I have since tried a few things...
Changed pixel density in rom toolbox (works once rebooted, but only till I stop using)
Changed from miui to ICS (no difference, but took an hour for it to start)
Am I looking at buying a new screen?
Edit: tried another battery, no success (didn't expect much)

I had similar issue with my phone. I do not think it has anything to do with software.. but yours is far worse thn mine.. I only had minor flickering which could only be seen sometimes and you really need to notice it with black or white background.. I tired diffrent roms it was on all of them.. I switched back to original rom.. and then got my screen replaced underwarranty... working fine since then..
OK thanks, ill give them a call today.

Had mine flickering in the same fashion. Out of warranty. Took it to a repair place and apparently it was just the screen connection was loose - thats what they told me anyway - $80 later everything worked again - probably ripped me off but im not a hardware tech so didnt want to screw with it myself
I'll have a look at a disassemble guide today, see if I can fix the cable. Thanks man, generally screen flickering is from a loose cable.

Well today I found a fix...
I accidently left my phone in the car when it was pretty hot. Seemed fine when i used it for a few minutes so i assumed it was water damage and decided to take the battery out and leave it for a while.
Came back to the phone after i had done the shopping to see if it was still working. Nope... It was noticably colder though as the car was now in the shade.
I ended up getting a heat bag and wrapping it around the phone. The screen almost immediately started working and the screen was perfect.
