I have Panasonic 1080i and yesterday when I was watching TV, out of nowhere the TV set made a blow sound and I can't turn it on since. It got power, the green power button is blinking when the TV is on. Can somebody tell me what the problem is, if anybody experience the same issue... Thank you...

If I was to guess, I would say an Electrolytic Capacitor Failed in the Power Supply.
If you have no way to send it out for repair, and you are a little electronicly inclined, you might open the module the cord plugs into, and look for a Bulging Capacitor.

What model number is it? Does the light blink in a pattern? If so, what is the pattern/how many times does it blink?

Have you tried unplugging and plugging back in the TV? Does this change anything?
