Many flat screens develop power supply issues like this due to low quality capacitors (85 degree instead of 105 degree). If you are handy you can examine the power supply board and visually see if any of the cylindrical shaped capacitors look discolored or expanded like the are going to or have burst. For many you can buy a replacement board.
www.shopjimmy.com is great for this.
