Hello , my name is Jack
Perhaps I can help you with this problem but first i would have a few questions ;
Is the tv turning on at all and then cuts off while playing or it just flickers on/off constantly ?
Did this problem happen all of sudden or gradually got worse over the last few days/weeks ?
Customer: replied 1 year ago.
