Re: Sony KDl-70R550A bad screen or backlight??
Seeing as this model is edge-lit it would seem one or more of the LED's have shorted. -

The third picture doesn't have the darkness, so it isn't there all the time, correct?Comment

Could be a tab bond issue.Comment

Example there, if a little pressure applied to the tab bond clears up the picture then you may be able to shim it: https://www.youtube.com/watch?v=vCExlSnG4yYComment

Another example there with a sanyo, I did one a while back for myself, I only did the bad tab and only shimmed one side, NorCal did a thorough job on it there: https://www.youtube.com/watch?v=purk_SyiT44Comment

Hello,
YouTube video of the problem encountered: https://youtube.com/shorts/q7TLNv36LUo
I am a pro and I have a problem that I have never seen despite my 7.5 years of experience on my own and my thousands of repairs, on a customer's Dell G3 15 3500.
On this PC I have already changed the complete palmrest because the keyboard was no longer working properly.
I also changed the screen because the PC fell and the screen was broken.
I changed the battery with a new and original battery.
I also had corrosion/oxidation on the... -
Hello, I'm working on a new deskmod pc project and have a problem with my monitor, an AOC U34G3XM, well, I may have bricked it.
The monitor was dismanteled and the separate parts parts integrated in the desk. the screen panel alone is on the upper part, and main board/video board + power board on the back of the desk (not enough place on the cover to fit it)
At first everything was working smoothly, then I decided to change the connexion between the video board and the screen for a longer one. Still working fine
During another reassembly, I made a mistake, and... -
Hi everyone, hope all is well. I have run into a problem where my backlight screen is no longer working.
The original screen was beginning to show signs of faultiness. I believe it was part of the inverter board that was going bad. The backlight for the screen was still functional at this point. Well one night as I was tinkering with the laptop, my idiot self forgot to disconnect the battery from the motherboard. I attempted to reconnect the EDP cable onto the motherboard, and as you might guess, I saw a nice spark from the cable and the port. Don't worry, I'm still kicking myself... -
I have a 2019 75" x950g, and while playing a movie, the screen suddenly went dark in a weird way, where it faded towards one corner into being fully black. Now the TV turns on, and the backlight comes on, but there is nothing displayed except black. Sound still comes through the TV speakers, and i have tried doing a hard reset using the volume - and power buttons while plugging the display back in, but it did not fix it. I can confirm that pressing buttons on my remote is still doing "something" because I'm hearing sound still, even though the screen is black.

I am just wondering if anyone has boardview+schematics for HP Probook 450 G8.
Computer is missing screen backlight. The backlight fuse must be kaput. I know the fuse is located on the motherboard because we tried a different working screen and it, too is missing backlight.
Perhaps, if the boardview+schematics are not available, someone can point out where the screen backlight fuse is located. Thanks.
