Hi, I’ve bought this unit with some as i thought small failure. When I plug it to socket it starts turning on and off every couple of second, almost same frequency as samsung logo on bottom of screen. While turning on screen backlight turning on and after 1 or 2 seconds off. I thought like most of cases with “flat TV” it’s power supply board. So I’ve ordered one, second hand, checked, tested with warranty. Today I’ve put it in my TV and there is still same story. Only one change is (I think) backlight is brighter on new board than on old one. Do anybody have any clue what can happen? Previous owner told me that TV stops working by its own. One day he watched TV and was fine, next day want to turn it on and nothing happen. Thank you in advance for any help Kind regards Kriss
Kri Ss that looks like a bad backlight array. Dismantle the panels and check the LED backlights.
