We've been having some issues with the upper half of the screen flickering, especially with whites. This stopped for about a week and then on Saturday night, the TV popped and shut off. Of course the LED is blinking 7 times. I have ordered a SC board from ModusLink as it seems they are hard to find. I am hoping to have the TV repaired by this weekend. Any tips would be appreciated on checking the SU/SD boards as well.
