Black screen on G4 Stylus - G4 Q&A, Help & Troubleshooting

Hello....
I'm new here, but hoping someone will be able to help me with my problem.
I droped the phone and smashed the screen.....nothing new, right
I have got replacement screen....after fitting it and turning phone on what I get is only black screen and backlight.
There is sound, and phone seems to be working, I can make call...ringtone is rining, alarm clock is working as well.....no life at all in the screen, not even start up logo.
Just backlight.
Anyone have any idea what that could be? Faulty new screen?
Reale thank you for any clues and advices .....

How can you make a call or set the alarm clock when you can't see anything?
Anyway, I guess either the connector was not seated well, or you got a faulty screen.

O2 XDA Orbit Screen Replacement

Wondering if anyone can help me with this or has experienced the same...
I got a used XDA Orbit with a cracked LCD screen, when I booted it up the screen came on and was partially usable above the crack. I decided to order a new screen to fix it, and after putting the new one in the screen doesn't light up at all. I thought, maybe the new screen is bad, so I put the old screen back in but it won't light up either. Any ideas?
FYI I have experience in repairing cellphones and flashing and unlocking, etc., and I have learned ALOT from xda-developers (thanks all you guys, you are incredibly helpful, generous and intelligent!). I'm stumped on this situation, is there something I need to reset or a pressure/contact screw that needs to be in place before the screen will light up? I appreciate all responses!
I have exactly the same problem.
After case change from O2 Orbit to Artemis case the screen does not light up at all and there is nothing to see on it. The device boots normally and the touchscreen reacts under Activesync.
I changed to a new screen with the same result and also flashed the ROM with SD-method... the screen remains dark while the device works.
Maybe the antenna contacts of the backcase have all to be fitting, closin some "case open" detection circuit" so the device starts electric power for the screen?
Any help appreciated, love my P3300/Orbit.

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] Sprint LG G2 - No Backlight !!

Hi There,
I bought a Spring LG G2 LS980 on ebay with an non-working backlight with cracked screen. At the moment, I thought that the screen was broken beyond the LCD and that replacing the Screen, LCD and Backlight it would work. So I bought a new screen and replaced it like any other G2, but now the phone turns on and sounds tell me the phone is working and responding to my touch, but I can't see anything! The status LED is my only indication if the phone is off, booting, on or charging. Is this a software issue or am I gonna have to replace more chips? Thanks,
Sincerely,
Sohaib
EDIT: So i did some testing around, and it seems like the flex assembly with the power buttons gets super hot when the phone is supposed to be on. When I press on the lower right contact between the screen and the assembly, the backlight flashes for a moment, so it looks like the connector is damaged. It is a hardware issue. Thanks,

Dropped Note 2. Display blank

Hi,
I dropped my note 2 and the display is blank after that. The motherboard is fine. The phone is booting up and the phone rings when someone calls.
However, even the touch functionality is not working on the blank screen.
So, what do you guys think, just a digitizer replacement will work? or do you think it might need a full LCD assembly replacement. If latter is the case, I might as well dump this phone as its almost End of life.
thanks,
Hi Guys, i am also facing the same problem. The phone was dropped and after an hour the screen started turning blue and within few hours the whole screen went dark blue ( or nearly black). The phone is still switching on and the bottom and side buttons are working but screen is black.
Do i need to replace the screen only or the whole display kit as asked in the first post?
Also i want to take backup of all my contacts,sms, whatsapp messages and other stuff. Is there any way i can do this when there is no display on the screen? Need a solution on urgent basis.
Thanks in advance

Nexus 5x screen replacement problem

After screen replacement of my nexus 5x it worked the first time. After a couple of minutes suddenly the screen at the bottem became very hot and the screen stopped working when trying to poweroff/on again.
Since then I'm not able to make it work again.
When trying to poweron it is a backlit black screen that becomes hot at the bottom ( where the headphone jack is sitting )
Could this be a connection problem or is the digitizer simply broke ?
Rgrds,
Bump.
After replacing my screen I got a "fizzle" noise and the regular beeping. Then turned backlit black and got very hot. I had no idea WTF was going on with it. So I put my cracked screen back on and everything is back to normal. But I would like to get that new screen on permanently.
Any tips on this would be helpful thanks in advance.
