I've had the 40h80 for about 6 months now and I love the picture and performance - up until this week. I have not been able to get a picture for the past three days. Toshiba Tech came out today and thinks it is a problem with the integrated circuit on the power supply but won't be able to troubleshoot further until new part arrives. Any ideas in the mean time? The problem occurred very suddenly and now the only indication that the TV is turned on is a flashing light next to the power button on the TV. I'd appreciate any ideas you might have.
