What could be the source of the problem if my LG 55 oled 4k tv has vertical blue lines showing?
The blue vertical lines always show on the blue areas of the screen. What can I do to repair it? I will repair it myself if I had to but I need to know the source of the problem. Bought this TV 2 years ago $3,000 now I can't enjoy its beautiful picture.
Any help would be appreciated.
 
wow, 3000$ and just one year of warranty ^^

Which source are you using? TV´s internal tuners or external device like a receiver or PC with cable connection?

try updating the firmware
reset the TV to factory default

maybe a connection is loose on the motherboard of the TV or solderjoint or a ribbon cable between LEDs and power

replacing the whole motherboard could help
