Customer: replied 1 year ago.
It might turn off and on a few times then it stays on with no problem it's always when I first turn the tv on for the first time
Expert:  Shahid replied 1 year ago.
ah OK, thanks for the info.
There are few boards inside TV that can be cause of this symptoms, either power supply board or main processor board.
It needs to check power supply output volts such as 5V, 12V DC with multimeter to determine power board performance and volts are low or not stable then swapping the power board will help to resolve the issue.
Do you have multimeter and can check volts on power supply board to proceed further if wish to repair the TV yourself?
