Chosen Solution
I have this 55” Samsung tv and randomly started having this issue. I have tried replacing the t-con board but didn’t work. Also if I check the ribbon cables and check which side of the panels the issue may come from it is on both sides of the panel. I have the tv open so can get more images. Can anyone help?
These are the the pcb boards
@bananabread04 errors like those are commonly caused by either the main board or the LCD panel itself. Since the schematics for the panel are not available, I suggest you try a new main board. Check the LCD driver boards (boards connected to the panel by very thine ribbon cables) see if you can find any obvious damaged parts
