Brightness wont change after changing lcd screen - G2 and Desire Z General

So long story short i fell on ice and somehow my g2 lcd screen cracked. No biggie bought a new one and changed it. It works i see everything fine. The problem is the brightness is permanently stuck at 50 percent. It wont go higher or lower so could anyone think of any reason this is happening? I opened it up again and checked the cables everything is attached perfectly fine. Any help would be appreciated. Also when i adjust the brightness, the touch buttons like home menu etc change their brightness values but not the screen.

I succesfully replaced my screen in my Tytn but...

Everytime i touch my screen or phone, the brightness goes to maximum (as bright as the camera) when i don't touch it, it goes back to normal. Pretty fancy effect, but i doubt that's good for the battery life. I checked all connectors (including camera on mainboard) and everything seems fine.
Any ideas what could be wrong?
So, the display doesn't go off completely until the phone suspends? If that's the case then you got a transmissive display. I hope your previous display wasn't a transflective one, otherwise your replacement was a downgrade...
The backlight goes off after 20 seconds (its configured like that) and then it doesn't flicker anymore. It only does the flickering (normal backlight => i touch it => maximum brightness => i don't touch it => normal backlight) when the backlight is activated.
The weird thing is, that it also does this when i touch the case and not the screen, this makes me think that it's fixable.
I need some help here: what exactly is the difference between a transmissive and a transflective display?
Problem solved. There was not enough pressure on the back of the upper side of the slider. Put in a little piece of plastic to keep the pressure on the connectors. Now working fine.

[Q] Do my Softkey Backlights work OK?

Hi,
I bought my wife a Wildfire but the softkey backlights are a bit of a pain - under both 2.1 and 2.2.
They appear to be ambient light sensitive - so they come on when it's dark and go off when it's brighter. However, it has to be really dark/dull for them to come on - and I think the sensitivity is set too low.
I can't find any way of adjusting the sensitivity - and it is not effected by the brightness controls. No way to keep them on permanently either - like my Desire HD.
I'm just wondering if the sensor is faulty or if it's just normal behaviour and we need to get used to it? it needs to be twilight with the lights off for them to come on - or really dull internal lighting. They never come on outside unless it's just about night-time.
Let me know your experiences?
Cheers - and a happy new year.
Well if it helps if anything Myne is over sensitive

Im sure it is automatic and does not use the ambient light. There is no setting for this that i know of. Im sure if u just look the phone and unlock it the backlights come back on.
I believe it works with the brightness of the screen, so if you set it to automatic brightness then it'd be automatic. otherwise it'll just follow the brightness set.
I read on another forum that the sensor is behind one of the speaker grills.
That does seem to be the case; on my Wildfire, if you cover the righthand side grill, the lights come on.
The sensor seemed to be on the black screen frame - near where the notification light was. I could get the lights to illuminate by covering it up too - but as soon as pulling my finger away, they would go out.
Anyways, my big-fingered wife couldn't get to grips with the virtual keyboards on the small Wildfire - and I tried as many as I could - Swype, Better, various T9s etc. So we still had enough time to exchange the phone to a physically keyboarded Android phone - she got a SE X10 mini pro.
Thanks for all your help though...
I think its in the black strip by the htc logo

[March 17] [Q] Backlight problem

Hello,
I'm having a very annoying problem with my HD2 : the backlight doesn't work.
I can see the screen, but very badly, when I put the phone to sunlight. It displays normally the sense screens and the keypad is working, but it is impossible to use the phone.
I was using the CHT theme, but I did a hard reset and I'm now on the original sense and it still doesn't work. I also tried to retrieve the SD card, the battery. Nothing worked.
Does anyone already had this problem ?
Thanks for your help !

Sorry to tell you this but it sounds like your LCD or digitizer is going out. I am more inclined to say it is your LCD as tbe brightness of the screen is the only tging affected. If it was the digitizer your touch functionality would be affected also.
Have you went to Settings/Sounds & Display/ scoll down to Backlight and adjusted the brightness of the display?

i will try to adjust the brightness manualy, but as i just realized a hard rest, i think th default parameters are on...
But luckily it is still under warranty so my HD2 won a nice trip to the shop !

Help. Atrix screen won't turn on

My Atrix's screen randomly stopped displaying anything. You can see that the backlight turns on and off but nothing ever displays. The screen isn't physically damaged and the touch sensor is also functioning just fine. If I plug it into my Lapdock - I can use the phone with no issues, I'll just never get any sort of display on the cellphone's screen (Outputs to Lapdock's screen just fine).
Any ideas or suggestions?
are you able to adjust screen settings when you're on lapdock? (and does this change anything?)
It does sound a hardware issue with your screen... maybe others on here can offer more help
Just tried playing around with the settings - no luck
Do you think maybe the display cable somehow disconnected? I'm not sure how the Atrix is designed but I think you'd normally have a separate cable for backlight, touch, and display. Maybe I'll try disassembling it and report back.

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!
