good day ok i have this issue with my tv ..after about 20 minutes of playing the screen flickers then red vertical lines flash on the screen and after a while the screen goes black but continues to talk..if i power the tv off then on it will come on back but after a while it will repeat the same process,,did some research was told most likely the tcon board .. so i went ahead and change the tcon board i also change the power board but the problem is still the exact same ..anyone can give any insight what might be the problem,, do you think it might be the main board or the cables,, i kinda rule out backlight as it comes on bk same time after power off and on,,i dont kno anyway so any input would be appreciated..
