Waited for months to find this used main board cheap, It finally arrived today and after installed, everything works fine except that the screen is slightly darker on the right side. All leds are lit but the screen is about a half shade darker. I am thinking the connections between the main board, lvds, tcon or tabs that connect to the bottom of the screen. If anyone has come across this problem also, please advise. Thanks

Re: LG 49UF6490 screen issue
Here are pics of what I got. Its the right side that's a shade darker. Switched tabs, lvds and cleaned connectors. Even did a _IN STOP. Difference is quite small but I can tell. Picture looks great from about 5ft. Any advise on what is causing this?Attached Files -

Re: LG 49UF6490 screen issue
make firmware update or downgrade to let the T-CON firmware match the Main firmwareComment

Updated software but no change. New Tcon solved the problem. Something on the old one must have been bad.Comment

Hello everyone,
I am experiencing a BIOS-related issue with my Dynabook Satellite Pro C50D-B-100. When I power on the laptop, the screen stays black, and there is no response from the system. I suspect a corrupted BIOS.

Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!
My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.
This time the original cable broke too close to the screen, it can't be fixed without tearing the screen... -
Hi everybody
Since day one I'm having an unpleasant contrast/brightness issue on my Asus laptop.
Basically while watching movies, if subtitles appear on screen, the contrast or the brightness of the entire screen increases a lot (not sure if it'is brightness or contrast), disturbing the viewing of the movie.
Last year I replaced my screen because got damaged and this contrast/brigthness issue persists. It happens only on the laptop screen, in fact If i plug an external HDMI screen the issue does not occour on it.
It occours both on ubuntu and windows...01-01-2023, 05:12 PM -
Hello Everyone,
This is my first post so I will try to be as precise as possible without making this post too long winded. Unfortunately I don't have pictures of the original problem but I included images of the TV internals.
I have a Sharp 70LE660U. The problem started a few months ago with the bottom row looking out of sync and was dark on the left side and then fading to transparent on the right side. Shortly after, a dark cloud appeared in the center of the screen. The dark cloud started small and shaded but the image was visible. It also affected the menu area.... -
Hi all,
Because of two bright spots and a couple of dark spots I decided to replace the backlights in my Samsung UE48JU7000. See attached photos:
I thought all went well, but after full assembly and testing it out it turns out not all is fine. The backlights are completely fine but I have some weird issues on the right half of the screen. Since I didn't really touch the T-CON board (apart from taking out the ribbons of the display and reconnecting them on assembly) it would be weird that the issue is with the T-CON board... But based on the behavior of the service...
