I have a Panasonic Viera TV that will quite often require unplugging and plugging in again. Sometimes it will turn on fine, but it happens probably 2 or 3 times a week that we have to unplug it. I will see the power light blinking after trying to turn it on, but no power will come to the TV. I think it's 2-3 years old. Anyone have any ideas?

Model number? Count how many times the light blinks (this is a diagnostic code that will help narrow down what is wrong).

Also, have you tried updating the firmware? Download The Firmware Upgrade For Panasonic Plasma Televisions
