My fairly new devant LED tv's display wont stay on. When i power it on, it displays a picture for a few milliseconds then goes black then on again for a few milliseconds and off again over and over again. i know the TV really doesnt restart because when i press the Menu button on the remote, the TV's menu screen pops out but the display goes black and on for half a second then black again on again over and over again but i can still see the the menu screen. If i select an item in the menu options like Audio Settings, it responds. But again the display just goes on and off so quickly over and over again. The problem started when i used the tv as display out from my laptop via hdmi. It was doing fine. I was actually playing a game and after one game, i decided to change the brightness level of the TV. It was on that moment that when i tried to increase brightness on TV menu settings, it started to turn off but it went back on and was ok. I increased the brightness further and then it started the on and off cycle there on. What do you think is the problem? Please help. Thanks.
