No backlight on screen - 8125, K-JAM, P4300, MDA Vario General

Dropped my phone in the toilet, fished it out and brought it back from the dead-again. After I let it dry out for a day or two, everything worked, except the red and green buttons were constantly lit up. That was when the screen was completely backlit. Now the screen won't light up at all, and I know it's not the backlight settings. Is this fixable at all?

Same problem. Replaced broken LCD with new one. First it only gave white light. Now it works fine, only no backlight. Who knows a solution?

Mine is all good now, so if you want a working device or parts, let me know

white screen of death?

aright previously my LCD screen was cracked well i got the replacement LCD screen and it works fine. BUT my problem now is that its just displaying a white screen. Nothing else. I take off the battery put it back on turn the phone on and i get a white screen no letters no nothing.
Does this mean my phone is a brick?
i still get response when i hold down the comm button it vibrates. The volume slider responds with the volume going up and down. and when i try to hard reset via holding the comm button,voicebutton,camera button and hitting the soft reset button it responds to it and resets the phone apparantly.
So i know for a fact the actual phone works..but its not displaying anything but a white screen...is there anything else i can do ?
If you have replaced the screen yourself, it may be worth trying to re-fit it again. Make sure the connectors are in pefectly, and make sure there is no dirt on them. If the pda still responds to button presses, it's fine, it's only the srcreen that's damaged/non-functional...
To see if this is the case, try tapping on the very to left of the screen, and see if you get the start menu pop. If you don't it's prolly the connector not plugged in properly, if you do, then the connector may be damaged...
ok im trying now..but how could it be the screen if the screen is giving me a perfectly white screen and its been tested to be working correctly?
sweeet i reconnected everything and it worked thanks for the recommendation dood much appreciated

Nice to see that my reccomendation worked for you. I've never replaced a colour LCD screen before, but some of the B&W ones i've replaced have had similar faults. It's the same with old cartridge games if you think about it, you used to have to blow on them ocasionally...
Modern technology may be perfect in every respect, but the manufacturing methods arn't.

Screen went white & buttons didn't work.. took to fix phone... and...

Screen went white & buttons didn't work.. took to get phone fixed... and...now buttons work but the screen has a weird yellow tint
what is the problem, and how to fix
bump. anyone?
Can you say a bit more about it. How strong is this yellow tint. Can you upload a picture.
It's difficult to know if this is caused by a new screen that has a faint yellow tinge or whether it's a definite fault.

My phone started getting the white screen issue, the buttons stopped working.
When I'd turn the display on, it would be all white, id have to press it a few times then it would be ok, the buttons seized to function.
I took it to get fixed, the buttons now fully work, but the screen has a weird yellow tint all over. It didn't have it before. I was mad at the repair shop, the guy told me that its the LCD screen connector cable or whatever... but I don't believe him, as he doesn't seem to know wtf he is saying..
please help
Mine started doing this recently. Screen fades to white and nothing works but I can still hear if I'm on the phone. For me, turning it off and back on resolves the issue (I can see the display again). I suppose some aren't so lucky..
More than likely the LCD connector cable has a problem. Why he didn't fix it, I have no idea. If you feel up to taking it apart, you may be able to push the connector in further, OR you could buy a new screen. Then again...
Hi there
I have rebuilt many hermes with the same problems. I researched the issues on here and elsewhere - Its nearly always related to the entire Dpad/cable/connections . I have repaired nearly all of these quite simply by dismantling them and adjusting/cleaning and reassembling them - things move and get out of contact etc and this is what happens with these - get a torx driver and have a go - after a few tries you will usually solve the problem
Happy to assist anybody who would like a hand
Kind regards

Backlight Replacement

My buds Droid 2 back light doesn't work anymore as well as the touch screen digitizer. Is the back light in the LCD itself or is that a seperate part? I told him I would fix it and I need to know what to order.
I'm having a similar issue, My wife got the phone wet, so we dried it out. That part went well....
Well she got a new phone, and I put the Droid 2 in a draw, and recently found it again, deciding to look it over, I charged it up, turn it on.
Here is what problems it has, No Backlight on the LCD display, No LED Nofication lights, No keyboard lights, No Digitizer touch.
The phone boots and works, sounds work, OS is intact and under a flashlight I can see the screen.
my question is does the ribbon cable control all of these? or are the seperate problems?

LG G2 -- Screen brightness can't exceed 40%

Hello.
The other day my phone suffered a little water damage. Not submerged in water or anything, but a couple drops found their way into the phone. The phone was turning off/on and functioning, but the display was black. I could feel buttons being pressed and stuff...the screen just wasn't illuminated. Well, I left it alone for a while, and now the screen works to a degree.
It's functioning perfectly, except it can't go above 40% brightness or the phone's screen goes black. As soon as I move the slider at or below 40%, the screen works perfectly again.
Obviously whatever illuminates the screen is damaged to some degree. The same thing happens when using apps like Lux...so I'm pretty sure it's a hardware problem now. I'm wondering if anyone has any idea what exactly could be damaged so I can fix it myself, or have anything to try before taking it apart again.
Thanks!

Did You ever get to the bottom of this?
Having the same exact problem?

Is the LED notification light part of the screen?

Screen on my G2 was totally cracked up but the LED notification light still worked. Was red when I plugged in the charger. Was green when I turned on phone.
Got the screen replaced and now the LED notification light doesn't work. Charge the phone and no red light. Turn on the phone and no green light. Options for LED is turned on.
Is the notification led integrated into the screen? So I may have a faulty replacement screen?
Also read that maybe a factory reset may work but thats a last resort to check cuz I don't feel like setting phone all up again.
On a side note..do those screen repair stores you find in the mall usually use OEM or crap quality replacements? Je told me oem but i trust no one. Noticing as I press keys as i type I see parts of screen near finger get a little darker like if u press down on a LCD screen too hard. Other than that the screen is fine so far.

No its not.
Its a seperate part that attaches next to the selfie camera on the logic board.
Looks like the shop was in a hurry and forgot to connect the LED
As for the screen, I can say you have an aftermarket non OEM.
OEM they use LOCA or OCA to bond the Digitizer to the LCD.
By doing so, you have no weird darker/lighter effects when typing on it.
Just like the stock screen.
If you have those effects, I would recommend you have them replace the screen with one that's OEM and not an aftermarket.
My first screen repair story went like yours only I swapped it in myself.
Come to find out the seller sold me an aftermarket screen claiming it was OEM.
I had him refund me for it since I called him out on it quickly
Darn...hate confrontation so was hoping it was part of the screen so i can easily tell him to fix. Now he can just tell me it probably wasn't working due to dropping it but I know it was working. Could always fight the charge on my credit card if he's unwilling to do something about it.
As for aftermarket..i can tell him what you told me but he could jsut stick to his guns, lie and stay "its OEM" and probably nothing i can do about it.
Thanks for the info!
Using a light...it looks like there's nothing in there where the sensor/LED shoudl be..its like i can see to the back of the case.
EDIT: Opened up...the whole proximity part is missing!! I'm assuming the LED light is part of that since that's not working and its right next to it.
EDIT2: I guess the IR blaster is part of that too...lol
Thing that pisses me off now is that he didn't put in my factory stock part and will replace it with a possibly crappy aftermarket part.
I'm demanding some money back for this nonsense.
