Solved! Blue Screen

[Dave624]

I recently replaced the backlights in my 55" samsung led tv. when I turned it on the screen is blue. any thoughts?

something else were damaged while replacing the backlight

check all connections, cables and flexes if connected correctly again
all screws inserted as well for cooling

usually the mainboard is the problem in such a case

Did you chose the correct video source in the TV´s menu or does it only show blue and nothing else, the Samsung logo is not shown as well?

I can't see the menu. Nothing happens just blue

I do have sound. Does that change anything?

something with the panel connection (LCD driver) or the motherboard itself is wrong.

Might be something like this (have a look at the description of the video as well):

Does your TV get cool air or is it in a furniture with no space to the side and back?
