Does anyone have any idea what the problem could be?
unfortunately I’m having the same issue, it was just fine last night. I watched a movie and went to sleep… the next morning I woke up to this. Does anyone have any idea what the problem could be?
Vertical colored lines usually show on a TV screen when the T-Con board is not working properly. Many times this can simply be caused from wiring that is not securely fastened. Other times the T-Con Board itself may be faulty and need to be replaced.
This doesn't always mean that the TV is broken. And there are a number of tips that you can try to solve the problem.
Tip 1: turn the TV off and on.
Tip 2: check the video cables.
Tip 3: switch between sources.
Tip 4: update the software.
Tip 5: reset your TV to factory settings.
I hope my answers comes in handy for you.
