I have a strange problem where my power led indicator flahses between green and red 12 times; then pauses and does it again. The flashing only stops when you switch the set off and on at the mains. The tv does continue to work perfectly even while the led is flashing. It only occurs about once every 2 weeks. Anyway Sony say they are aware of the problem and will be transmitting a new software upgrade to remove this problem. I think the transmissions are due to start on the 21st of Feb. for 4 days. By the way I have a 36NX200.
