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.

I9500 Screen flickering (Imp.)

Hi guys,
I have a galaxy S4 I9500 version and I have observed a problem with it. I was sharing media with my friend's Xperia Z via NFC, while doing that, my phones' screen started flickering highlighting clock at the top portion.
Later I turned off both mobiles' NFC and taken both mobiles close and guess what my phones' screen flickered again.
I checked it with my old Galaxy S I9000 which doesn't even has NFC, again S4s' screen flickered.
Then I went to service center to show this issue, as they were not having any other S4 there to crosscheck problem, they asked me to visit a Samsung mobile shop. There I checked it with three S4s' which were on display and I found that problem was there with each and every S4.
So guys can you check your phones' for this issue and will it cause any problem to phone as the time passes??

similar type of problem

i am facing similar type of problem. the diffrence is that i get such flickering whenever i am using the mobile data network after evry few minutes and the flicker is like a flash(means it lasts for a fraction of second). i started to have this issue from past few days and this is extremely annoying.

But I think it could turn into an issue because earlier my phones' screen was flickering and waking up automatically highlighting clock just like shown in that video.
I submitted my phone to them and they have replaced display with new one. Now it is not flickering automatically but it does while holding devices side by side as that sensor gets triggered by any magnet. So there is a possibility that the sensor could get permanently affected by a strong magnetic field and triggers the screen to wake up automatically.

They replaced display with new one and now the problem is sorted out.

Yesterday I tried something with my s4..
I disabled samsung link, clock digital(both of em), watch on, and dropbox.
The problem of flickering and clock appearing on top was GONE!! until......
I turned on the data network and found it coming back again...
I figured that it happened to me since i updated it to UBMG1 Indian firmware from BMEA
So i am now rolling back to the latter and sammobile here i come

Even i have also tried a lot of things... but problem was still there.... i think it messes with hardware and there is only one solution and tht is to replace the display with new one... if you find sonething to sortout this issue without replacing any hardware part...pls post it here....

Does any one got this solved.. as said by one member, even in chennai - tamilnadu, they are not clear on what the issue i am explaining to them, they just changed the motherboard. but no use still.
"S-view mode activates itself, dono why... it happened for me in a month old S4, i got my motherboard replaced, but still the issue is persisting. but the frequency became less. thats it. other than that no use.
as mentioned by one of the member, it is annoying as it happens any time u work with your phone. in any screen suddenly "

I got my screen replaced but in vain.. I think using the S view cover will help because the flickering is caused by s view initiation (black screen with clock) which is initiated by a magnetic sensor..
Buy unfortunately the s- view cover is costly and so I cannot buy it at the moment .
A possible solution is to turn the s-view service off to stop the flickering issue..
If any developer on the site could help us out..

- Actually am using the S-View Cover. But with no use, when its out of S-View cover it behaves erratic by switching to S-View display automatically.
-Yes you are right it can be a software problem ,but take my words, i used a S4 which i bought on launch date in India, i used it for 3 months, then i gave it to my cousin, and bought another new one - this is the one which is showing up this S-View Issue,
the old one which i had was a GEM, not even once i had this problem of S-View with it, both where of same SW revision level, hence there is something to do with the hardware.
am just waiting for the October 4.3 update, if this is not solved in that SW by any means, then am gonna **** on every Samsung technician in the service center, they don't even know the difference between Hall sensor and proximity sensor!!!! , for making them understand the problem in our phone itself is painstaking..
in between is there any change to bring this issue to Samsung's eye.!?

True the service center's technicians
Don't know anything...
If you report that the s-view cover also gives the same result instead showing the s- view when it is supposed then I won't buy it because I only wanted to buy it currently just to fix the issue..
Also just waiting for the android 4.3 update..

That's not a issue. It's s-view feature in phone. If your phone get close to any magnet/magnetic source then it will activate s-view screen.
A lot of devices like iPad and Nexus 7 have a small magnet in them to provide support for cover/accessories. If your S4 get close enough to that magnet on other device it will activate s-view screen.
I dont know exactly if your other phone that you are trying NFC with, has a magnet. but there should be.

I know that it is a feature but it comes just in between typing process or running through the temple (temple run) and it disturbs a lot so I thought of using the s- view cover so it will restrict the feature to only when needed out initiated by closing the cover instead of coming every time in between activity..

Not always, see i am just holding my phone in hand, or it is laid on a wooden desk, even then this flickering into S-View mode happens.

[Q] [HELP] Digitizer vs some weird BUG ?

for the past week my screen has been going whacked out on me.
the on-screen buttons would start clicking on their own, and sometimes the screen becomes unresponsive,
BUT
when i turn it off, and back on, it would work perfectly fine .
so i basically get a 50/50 chance if the screen going crazy on me...
now if it was the Digitizer, wouldnt the problem be ALL THE TIME?
as opposed to being random, could it be a BUG ?
Can anyone please help or advice, thanks !

If a factory reset doesn't fix it it is probably hardware. I have seen intermittent problems with digitizers before.

Have you called them? I don't understand why they would not honor the warranty.

Read the book that came in the box. Manufacturers defects pretty much always have a 1 year warranty.

I have a similar-sounding issue (on-screen buttons flashing wildly, et al.); I am thinking of opening the device to check on connection
Is it more or less likely, in your experience, that the connection between the display assembly and the board is loose from impact or whatever, or that the digitizer itself is just defective?
Thanks for your help.

I had the exact same problem on my device and it can be due to two reasons.
1. If your phone get extremely hot during use then the screen starts behaving abnormally.
2. If you had dropped your phone then there is a slight chance that you have damaged the digitizer.
I had the second problem and I have replaced the screen and it is working normally again.

I am no pro with screens, So i may be wrong, but it looks like it has been either burnt or had an impact with a sharp object in that area of the screen, return it for a new one, hopefully they will replace it.

Looks like the LCD definitely needs to be changed. It looks like it's burnt or either a reaction to a magnet but I'm not quite sure what can cause that. Costs can vary but directly from LG will cost you parts+labor+shipping. Check if that Orange spot still register when you touch it.

Options: Send to LG to get it fixed (probably costs more than $100+ depending), sell it as is and get another phone (won't get as much for it with the spot) or keep it and use it as is since it still registers touch (spot might be a little annoying).

hmmmmm :c you are probably going to have to replace the screen yourself (cheaper) or live with the yellowness

I've got some yellowness appearing along the top right of the screen. Its barely noticeable but its likely to get worse over time.
From what I can tell, it seems to be related to heat/warmth. Its winter here and after a walk outside, the orangish patches pretty much go away. They appear more intense when sitting on my desk next to my laptop (right near the vent).

it gets into the fastboot....but no display...i didnt tried it...but i dont think it will fix it...and if it doesnt fixes then ill loose the recovery...so didnt do that...

I dont think that factory resetting and flashing stock rom will do...coz all that happens in recovery and i can see any think that just a white screen...sometimes faint....must be a display or a motherboard problem....
but when it comes to display it is not broken or got damaged....might be motherboard must be burnt...but if so then why will the cell boot up without issues...
are there any chances of screen damaging due to heat...?coz it has got heated and i got this problem...
And all functions are working even calls sms wifi....everything w/o issue...just no display..
Should think on it..

Can any1 detect where the problem is so that I can fix it...

If you can't buy a new screen assembly to troubleshoot whether that's a possible issue then the only thing I can think of is wiping the phone and flashing the google factory image.
Are you able to download this and flash it through the command line using fastboot?

Hey sturdy I hope your phone carries an Indian warranty !! If yes the best way is to flash back the factory image and get it to your nearest lg centre !!
If u are not covered under warranty lg guys charge around 4.8 k INR for front screen with digitalizer !! You get a screen replacement on eBay for around 2.5 k !! If its the motherboard it can burn a dent in your pocket !!

Anywayz firsstly i opened up my monster...cleaned the thermal paste..re-applied it....Ok nothing is burnt on motherboard....everything works even usb....my computer is reading the device....just no display thats it...i tried to disconnect the display and see...still everything works no heat up...
so it takes me towards the screen problem....
Now is there any chance to screen plug getting damaged from the motherboard.... there are just two slots i dont think it has any chance of damage...
And also the screen is responsive but not display...i can swipe and receive calls and everything....just no display...
So what is damaged ?
As there are two parts of screen..

This is the exact thing whats happening
After a lot of research...i found that from the three parts which i thought i had problem with is that...lcd digitizer and gpu...
there is no digitizer issue...after my research...now left if lcd might have burnt out or gpu might have burnt out...

I'm really guessing here but like I said before, i'd say restore the factory image from Google to see if there's any software issues at play like a kernel issue.
At least then (if that doesn't fix it) you have the option of either sending in the device to LG for a fix, giving it to a third party repair shop, or buying the screen assembly yourself and replacing it that way.
Like NABENDU1 said you can get one on ebay or other sites, find the tutorials on youtube and you already seem to have the necessary tools so that'd be the cheapest way.
Though i'd say make sure you get the whole assembly to make replacing it easier, or it can get quite fiddly.
If it still doesn't work after that, then it may be a problem with the motherboard which would also need fixing.
Good luck figuring it out though.

The white ring stays even when it's off?
If you're sure you reconnected all the ribbons inside and wiping everything and flashing the factory image didn't solve the issue then it's safe to assume there's a hardware fault somewhere. Unless you or anyone else can think of what else it could be, it looks like it's time to try replacing the screen assembly.
Don't know where you'll be able to find one in India. Ebay might have one, aliexpress might also be worth a look, I saw one on there that ships to India from China for Rs. 4,070.40 / piece with free shipping.
Again good luck!
