Right side screen is darker than the left one

Dear all

First of all I couldn't find my TV model in the list so I picked the closest one

The problem is:

The screen was black with vertical gray lines, and because I'm a do it your self kinda guy I opend the TV and after a lot of YouTube and visual inspection of the t-con board I found a chip on it that has a burn marks so I ordered another board and replaced it and YES the TV works again :)

But :( the right half of the screen is darker than the left one

Now is this a faulty t-con or ribbon cable or back-light problem??

The TV model number is UE46B6000

Many thanks in advance for your help

Hey everyone

here are some updates:

1- to eliminate any compatibility problem that was referred to by

@danj i’ve turned on the tv with nothing plugged to it and the the right half of the scree is still darker than the left one (see photo)

2- moving on to the next tip from @oldturkey03 i’ve removed the bottom protecting panel under the t-con to fully inspect the ribbon cables and surprise surprise there is water damage on the right side connector

from screen cleaning spray i suppose

3- now before putting this fix to rest if anyone have a tip on how to order the right flat ribbon cable would be help full, don’t forget that i’m a hobbyist and this is my first TV fix :)

on the ribbon cable it says M 20861 105C VW- 1 TennRich

and i’ve counted 80 pins (which wasn’t easy :)) as for the dimensions its 42.5 x 44.5 mm

i’ve googled a bit and i found that people talking about how many volts it should handle
