Hi my tv was working just fine yesterday and I turned it on today and the screen is flashing between red, green, blue, back and white. Not sure what to do about this or if it’s just broken. Serial number: 1807gtc003170a01309 , service number: 65r615tcaa
I just unplugged mine from power for 60 seconds and plugged it back in and that fixed mine when it did that. Good luck!
Did you find a way to fix this? My same model just started doing it.
I did this and it worked for me as well. Thank you for your help!
