Samsung UE48H6620SV, no picture

[JRade]

The backlight was not working properly, I replaced it and it works
but when I installed the board and connected the 2 straight cables to the T-con, there is no backlight.

I connected the satellite receiver with a scart cable and there are tons of them.
When I disconnect one flat cable (left or right) there is a backlight, but there is no image on the display, but of course there is sound.
When the backlight is on, the entire screen is dark blue.

There is a voltage of 12V DC on the T-con and the fuse on the T-con is correct.
Please help, what should I do next?

Thank you!

check your tcon voltages, see if they're what they should be, some testing there and plenty more videos on the subject on youtube: https://www.youtube.com/watch?v=eGMJnTlPW1Q

make sure you put all the cables and connections back on, its easy to miss one on reassembly.
