[Q] NO display. Please help - G2 and Desire Z Q&A, Help & Troubleshooting

Hi,
I have a T-Mobile G2, original ROM. An hour ago, a very weird thing happened. Out of blue I picked up my phone to find a contact and I was stunned to see no display. The bottom panel/button lights were on, but there was no display. I only pressed power button to bring it out of standby. No liquid was spilled, no shock observed. I was just lying on tabletop.
I took out the battery and tried booting again (like WM sets), but no success. I can receive calls, apparently I can dial my last dialed number, I probably will be able to dial from the keyboard.
Anyone else how experienced something similar. I know the ultimate act would be to replace the LCD, but am just wondering if anyone else had observed this behavior and countered it without replacing the LCD?
Oh yeah, there is no warranty.
Please help.
Thanks,
MAK

Your screen died. Get a new screen.

that's a worst case scenario...give me some hope...

Same thing happened to my original G2, luckily I bought it at Costco so I was easily able to return it and get a new one.
Sent from my T-Mobile G2 using XDA App

So far, it looks like this is the only option. Can't figure out why it happened. It was perfectly fine before and it didn't show any @#$ signs >:|

I searched other forums and seems like I am not the only one with this problem. All they suggested was to take out the battery, mem card, sim and leave it for a while and when it put everything back in, the display was working fine again. Unfortunately, it didn't work for me, not even restoring factory default, not to mention going through that painful "shooting in dark" process.
I am already aware that if all things fail, LCD has to be replaced. Other than that if anyone has any other suggestion(s), it'd be much appreciated. Otherwise thanks anyways

Help required!!

Everyone has experienced some problems with their phone, whether its white screen/d-pad syndrome or some other fault.
Today my phone has decided not to turn on. It was working perfectly then all of a sudden screen went blank.
I have tried taking battery and sim card etc out and putting it back in. Phone won't even pick up charger.
I have had white screen of death before and dismantled my phone following alkizmo directions. This fixed my phone for a number of weeks, though problem started to re-appear.
Could this be whats caused my phone to switch off.
Does anyone have any ideas on how to get my phone to turn on again.
Warranty is well gone!!!
Seeing as there doesn't appear to be any ideas, I may go hunting for a new phone, though I'll probably take my hermes apart first!!

Yeaaaaa, kill the bast...rd and go for Diamond
My hermes just started showing the same symptoms. None of the front buttons work, not even the leds... I took the phone apart i did the foam trick but it didn't work. However, it could be because the mail button is faulty (it doesn't click when pressed) so I've ordered a flex cable which includes that button. Its a good thing I've already pre-ordered the touch pro, so its not too much longer with my faulty hermes..

Serious problem with my Galaxy S Screen!!!

Hi to all,
A couple of days ago I noticed that when I answered a call the colors of the screen looked bad, and I didn't pay attention to it.
Now my screen has transparent horizontal lines which are pretty visible, kind of like interference you get in computer screens when you take a picture of them.
I would like to mention that I haven't dropped the phone even once.
I'm considering doing a factory resest in hopes that it will solve the problem, but I doubt that it is a software issue.
What do you guys think?
Please advise
Itay
Sounds like a broken screen to me. And definitely like a warrenty case. Restore stock f/w if you have flashed and return it.
Restore the original firmware (if you have flashed the phone) and call the samsung service for the assistance.
the thing is that now I don't see it at all.
It's as if it came and gone.
I disabled my task killer and juice defender, performed a complete titanium backup, in case I want to restore afterwards, and now everything is normal.
It does sound like a hardware issue, but do you think there's a chance it is software related?
I'm asking because I purchased it in europe, and I don't live there, so sending it for repair is something I would rather avoid.
Of course, if it is indeed 100% hardare issue, I have no choice.
That is why I'm asking, to be certain and to see if there are others who experienced this issue.
Your replies are much appreciated
update:
It appeared again -> Did a Factory Reset -> It's still there -> Sending for repair.
Must be a hardware issue.
Thank you for your replies.
I've actually always had slight screen issues with my Galaxy S also. The screen flickers slightly once in a while. I don't know if the radio is actually the cause but it's the kind of thing you might expect from radio interference.
Has anybody else noticed this?

Nope, never seen any flicker. My screen seems to have a defect of it's own though, but I'm not sure if it's worth the effort to send it in, because I imported mine from the UK while I live in South Africa.
When in the sun or under bright light I can see a two vertical lines near the sides and a horizontal line on dark/black colours and when the screen is off. As if those pixels have a grey/brown tint to them. The line is mostly one pixel thick but in places it is two pixels.
They are almost impossible to see unless under sunlight where they are clearly visible where the screen is black.
Does anyone else see this or know anything about it?
Edit: Apparently it's just the motherboard or something visible through the screen and they all have it, so I'm worrying about nothing...
That's interesting...
It used to come and go, but I think now it's here to stay.
It's really annoying and the screen, while usable, is really not a pleasant sight to look at.
I've attached some photos showing the problem.
With a normal screen I would say that it looks that way because that's what you see when you photograph a screen of an electronic device, but the sad thing is that what you see in the picture is exactly what I'm seeing now.
I did a factory reset, so it's in german now.
I heard some Droid X had a similar problem, but didn't know Galaxy S was having it as well.
In any event, can you confirm that after a factory reset, I no longer have root access?
Just making sure so that they don't give me problems with the warranty.
seem like the phone was dropped, and the screen got damaged
the connectors are lose
double posted again....
Really?
That's very weird...
The only time it was "dropped" was from half a meter , it didn't fall directly but partially sideways, it was with a case, and it landed on its back, not on the screen.
I wouldn't even call that a fall.
Unless, someone in my family dropped it without telling me...
Either way, I think there's no escape but to send it to repair.
If you think it's a problem with the connectors, would you try and give it to some local lab to try and fix it or send it to samsung for replacement?
I faced similar problem.
This problem only occurs when I use the phone in 2g mode.
there are occasions whereby the signal bar for 2g is full and when I place the phone near some conductive surfaces the lines becomes very obvious, to the point of irritating.
nit sure if anyone has such problems too
I have same problems with horizontal lines.
I never paid attention if i am on 2g or 3g when it happens. I will now.
Edit: rooted on jm5
-------------
It seems that my phone too has started to do the same thing since last night.
I have called Samsung and am waiting to hear from them now.
I hope this is a thing covered in the warranty.
I have reverted to the local ROM for India and have deleted everything on my device.
Yet it shows lines flickering like you can see on old computer monitors.
Its not as bad as the ones on the attachment above but it is starting to annoy me.
It usually happens when the screen is completely filled with a single color except black.
Eg. When you pull down the notification tray down.
Also I seem to notice that when the wifi is off, it stops.(I dunno maybe a placebo effect)
aditya_t90 ,
I have sent it to Samsung for repair, and they should tell me in the coming days exactly what the problem is and whether it can be fixed under warranty or not.
I will update as soon as I hear from them.
Until then, try to see if it changes when you hold the phone differently, for example if you grip it more firmly or hold it in another way.

When did you send it in and when did they receive it(if you were not there when they got it).
Also how long has it been without your phone?
The samsung service center is shut in my area today.
I will go to them tomorrow and get this sorted out.
Its not like the phone was cheap or anything.
I actually sent it to my uncle in Germany because it was purchased there.
He went to the store where he bought it and the store owner immediately sent it to samsung and said that probably by this Tuesday or Wednesday (so tomorrow or in 2 days) he will get an answer from them and see what's going on.
aditya_90 ,
Just to let you know that Samsung are sending me a new phone to replace the damaged one.
I sent in my phone for repairs and they replaced the LCD module. The problem is now gone.
I suggest that you should do the same while the warranty still holds since it appears to be the LCD that failed somewhat.

CDMA galaxy nexus - unresponsive to touch

Hello everyone,
Basically went to unlock my phone today and touch screen is not responding, however the hardware buttons work fine. Now i've done some research and found other posts of people with the same problem, however their touchscreen problems seem to be fixed(temporarily, at least) with a battery pull.. mine however is still unresponsive after half a day and multiple battery pulls.
Id rather not have to send in for certified to replace an otherwise perfectly working phone.
Any ideas/suggestions would be greatly appreciated!

are u undervolting?
Nope, sorry forgot to say. Completely stock never unlocked or rooted.
Also i tried getting into recovery to try and do a factory reset but when i select recovery i just get the android on his back with the red triangle..
so instead i just went through the steps and unlocked the bootloader and booted up (in order to give me the factory reset without having to touch the screen)
It unlocked and booted up fine but still no response..
No new recent app installed and never had this happen before.
Mine did this after a few days of owning it, and luckily the store took it back and swapped it out with a perfectly working unit. Is yours within a few weeks of purchase?
Figured this out randomly. Remove battery cover. With phone turned on, press on the area to the to the left of the camera lens until the screen is responsive. My screen becomes unresponsive when the phone is dropped and this fixes it.

hrmm this does not seem to fix either. I also have never dropped my phone, although this seems to be worrisome if the issue is hardware related.
@ tmellen i purchased the phone from amazon and am a few days past my return date :-/
Guess ill just give them a call and hope for the best. Thanks for the ideas everyone.
(update) called amazon and they are sending me a brand new phone.
Knowing this i thought i'd try dailong's method again only this time i was quite a bit more "rough" with pressing down on that area, and it actually worked!
Ill still be taking the new phone once it gets here but for anyone who is having this problem there's a sweet spot on the left edge of the phone towards the top (looking at it with the back cover off) there should be a circle shape. press on that area really hard and it should fix.. weird
Experienced the same on my GSM version a few minutes ago. I had to call my mobile to get it to respond. After that it worked again as normal. I'll see if I get this issue again in the next few days. Hope it's just random
Had the same happen earlier to mine and I was on AOKP. I've had this happen to other phone before, shouldn't be a a cause for alarm unless it happens very frequently. Btw, next time it happens to me I'll give that left side of the camera trick a try.
mine got fixed by removing battery.

Black Screen, phone still works?

Hello XDA members, this time I'm writing to all of you to tell you something that happened to my Optimus G E987 from Claro Argentina, also, to ask you something related to the topic.
I bought this phone about 4-5 months ago, and I have taken really good care of it, without using any film protection or case, it was working perfect and with not a single scratch on it, not even a little hit.
But then, some days ago, I decided to "protect it" a little bit, so I got one of this:
htt-p://i[dot]imgur[dot]com/YtgK1aS[dot]jpg
htt-p://i[dot]imgur.com/la1kI5e[dot]jpg
(Sorry, I'm new to this forum so it won't let me post links)
I used it like.. dunno, 3-4 days. One night, my phone was on 53% battery, to lazy to charge it so I just let it like that. Next day I gave it some use, so it dropped to 33% of battery life, I had to go work so I turned it off. When I finished, I tried to turn it on again, but nothing happened, tried more times and nothing, then I noticed I liiiitle light in the screen, the phone was turned on, but with REALLY low visibility, almost everything black but with a little of sight.
I though it was just a battery problem, so I charged it, but to my surprise, nothing happened, well something did happen, the little bit of sight that I had just went full black with no visibility. I noticed that the touch screen and buttons actually worked, I could "easily" navigate through the phone by just using it as normal, but without seeing (you can do this by just knowing your phone a bit).
And that's the story, basically, after using that case, the phone "casually" stopped working properly, all I got was a functionally phone with a black screen.
I managed to connect it to my pc through wifi and launched Android Screen Cast, to see what was happening on my phone. The glow was at 100% (I tried changing it) and everything seemed normal.
If you don't want to read, here is a TL;DR
>Bought Magnetic* Flip Stand Leather Wallet Case for Optimus G
>Some days after, phone screen stopped working (phone was still normally working, just with a full black screen)
About the Magnetic thing.. is there any possibility that this was the problem? the magnetic thing?
Btw, I sent the phone to tech service because it was still on warranty and they have me a new one, now I'm scared of putting it again in the leather case I bought, I don't want this to happen again.
Something to comment? hope you can give me some advice, thanks in advance!
Also having similar problems as you. Somehow, i am quite sure its the stock rom causing the problem.
Had the very same issue few weeks ago, had to send the phone back to LG ( who replaced the motherboard :/).
I was also on stock rom, had root and unlock bootloader (of course I clean all that **** before sending it back).
For my part, I was unable to go to recovery and download mode was quit impossible to access (may be my finger fault )
BUT! some time if I let the phone off for a moment or spam the power key, the backlight turn back on until I power down the phone, so it's could be a software issue ...
Anyway, an other info, when the backlight was off, if i tried to change backlight level i was getting a error message about overeating or something like that...

HTC 10 Half of Display Not Working After Screen Replacement

The battery on my HTC 10 was completely shot and needed to be replaced. I'm a careful person by nature and this being my first phone repair, I bought an extra screen just in case something happened getting it apart. Followed a guide by jerryrigeverything on how to take apart the phone, got the battery replaced, everything seemed to go smoothly. When I went to test the display before screwing everything together, the new screen I installed lit up, but the right half of the display only showed as a repeating segment from the middle of the screen. Thinking the connector was loose, I disconnected and reconnected the display and made sure everything was tight: same problem. I reinstalled the original display, which I made sure had worked after cutting through the adhesive before I disconnected it, and now the old display is also showing the same issue.
The touch screen on the broken side of the display still works, I'm able to type PIN numbers and whatnot even though I can't see them properly. Only thing I can think of is maybe the connection actually got some debris or something inside of it? I don't think I damaged anything, as I was super careful, but it was also my first time opening up a phone.
Sorry for the inefficiently worded post. Any help would be really appreciated.
Did you resolve this?
I have exactly the same issue you describe after my screen replacement (with two new screens) Believing the first was a dud.
I have done many screens/batteries on my m7, m8's previously never having a problem.
I'm currently back to running my M8 and miss my 10!
Anyone reading this and has any suggestions they are all welcome!!
Thank you in advance
Exactly the same issue this guy has
https://youtu.be/RpdCuMiTOn8
I'm now wondering if it is just bad aftermarket screens?
Has anyone else replaced their screen successfully, if so where did you get the screen?
Thanks Rory
I have been having the same problem. I just tested screen number 4 that has the same exact problem. Is there a specific brand that is known to test well?
I dropped my 10 in water at work...believe it was a salty water at that. It stopped working completely. I opened the phone to check the internal components for damage and I broke the LCD doing so. I replaced the battery and the screen at almost the same time. I think it may have been a week or two apart.
The battery is still working. The screen worked initially but the phone kept getting really hot and the heat kills the phone. I tried keeping it cool at all times which kept it operational. It hasn't been activated since I quickly replaced the phone with another of my lines upgrades. I went back to the phone to check it out and try using it as a replacement for my daughter but the screen no longer works.
The battery charges just fine...the led light indicates that well. I've tried reinstalling it several times with no success getting the screen working again. I tried the original screen to check and I could see light and it was responding but its not usable so I'm stuck with a phone that has a new non-working display. I think the brand was called DIYRepair or similar.
If anyone has encountered this and has advice...I'd be happy to try anything.
