few days ago (unfortunately cca 2 weeks after guarantee expired ) while watching TV, there suddenly appears purple (or pink?) glitches/vertical lines on screen (see attached photo) 10 cm from top border. I have done some research and find out that it can be either defective LCD panel (the worst case) or bad TCON board (the better case) and if there are horizontal lines it is always dead LCD, but as you can see on the photo lines are vertical. If it would be TCON, I can buy new on e-bay or somewhere and replace by myself, but I am not sure if it would help and TV can be repaired. Can anyone confirm or help in any way with diagnostics? Thanks in advance.
TV model UE32K5572SUXXH
PS: if needed I can take a better photos or video...
Ok so today i disassembled it, checked all flat cables as you advised and reconnected each one. Did not help
Then I try to switch on TV with left/right cable from TCON -> LCD disconnected to check the LCD. The result was that one half of screen was completely white.
