LG G2 -- Screen brightness can't exceed 40% - G2 Q&A, Help & Troubleshooting

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!

No backlight on screen

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

G1 Screen problem

Hello, My G1 has just suffered a problem, i was scrolling down a web page and the screen faded out like it had lost power but the backlight was still on, the keys lit up and it still could make the trackball clicking noise when you moved it. I took out the battery and left it for 5 minutes and rebooted my phone and the screen turned on for about 3 seconds and faded out like before but it did boot into android as I heard the notification/startup sound. I think that the screen has burnt out but im not shore so has anybody had this problem before and/or might know how to fix it
Just some more infomation, If the screen dies and I leave it for a few minutes, when I unlock it or slide the screen up, the screen works for a few seconds but then fades. Also the fading looks like the screen lost power or like its losing pixels
From my experience with phone hardware this doesnt look like screen problem, but rather the lamp driver in the motherboard. the only way to narrow down is test the motherboard /screen with another phone.
If this is the case, it might require servicing the backlight driving circuit, which by far requries soldering/desoldering some components in motherboard.

[Q] Screen crack and blackout after phone call

So my sister who also has an Aria dropper her phone and now there is a huge crack on the screen. She doesn't have insurance so she is trying to find an alternative way to fix it.
Simply replacing the screen would work, but another problem started happening when she cracked the screen. During a phone call, the screen will turn off, as it should, but when the call has ended, the screen stays off and the only way to turn it back on is to either pull out the battery and reboot the phone or to plug it into a charger.
Does anyone know how to solve this problem? Will replacing the screen fix the blackout issue? Or is this phone just trashed forever?
sounds like it destroyed the phone and the proximity sensor. i'm not sure if replacing the screen will fix this.
I actually had the exact same problem after dropping my phone during a call. I noticed that I didn't have to pull the battery to end the call if I held it up super-close to a really bright light (desk lamp, etc).
There were many times when I was on the street (in nyc), and had to find a bright light to hold it up to.
I dropped my Aria right on the corner with the ambient light sensor (in the upper right corner), which shattered the glass right in front of it.
Amazingly enough, after a few weeks, it started to get better and better - and now, nearly 4 months later (yea, i just deal with **** lol), it will hang up cals properly.
I'm actually working on replacing the screen right now, btw

g2 display water damage, which part to replace?

my d800 was immersed in the pool for a few minutes.
tried heating it with a hair dryer immediately. then left it in rice for a couple of days.
after charging for a little bit, i hit the power button. phone turned on like normal, but lcd was all messed up.
it was like distorted rgb dots all over the screen. and there was no haptic feedback to my touch.
the phone functioned perfectly - ringtones, led notifications, etc. only, i couldn't see anything.
i left it off for a couple of weeks, and switched it on again today. the display is only black now, but i can see it is backlit, compared with when the screen is off. and the phone vibrates now when i touch the screen.
so i'm guessing the digitizer works?
looking to repair it myself, whatever might need replacing.
any ideas, guys, on what i have to change here? or just leave it like this and hope it eventually works again? :laugh:
also, suggestions or links for items and instructions that might've helped you will be much appreciated.

[Q] screen doesn't work after water dmg

So my son got the tablet wet. I let it dry out for a few days then turned it on. Everything seemed fine. It went to home screen but the touchscreen was unresponsive. After about ten second's the screen went negative kinda then blank. It still vibrates and makes noise from notifications and volume buttons. But the screen will not work. Is there a screen replacement I can buy and would that work to fix my problem? If so is there also a video on how to do so? Thank you
