I had my tv on (which is excatly 2 years old this month) left the room, then came back 10 mins later to find that it was shut off....now i can not turn it back on with the remote or power button, its completly dead. i have checked that my power is working correctly in my house and other componets that i have are working in the same plug. any ideas as to what the problem would be???
thanks in advance
Power LED on front panel blinks several times, there is a delay, then repeats. After fiddling and fuming (mostly fuming) I found that changing the input signal source allowed the TV to be turned on. When I changed the input signal source back everything was ok.
In other words...
My TV is connected to my PC's video card via an HDMI connector. My card has 2 HDMI connectors. I moved the connector (the part that comes from my computer) from one HDMI out to the other. The screen powered up. When I changed the connector back to the original HDMI out I got my display back.
So yeah, try changing your input signal source. If you're using cable try switching to your Xbox/PS3/whatever, or vice versa. If you only have one possible signal source then I have no clue.
It's almost like the TV doesn't get any signal from the current cable then goes into sleep mode until it gets another signal. My problem had to do with me changing a bunch of sleep/timeout/screensaver settings on my TV/comp.
Hope this helps someone.

we have the same problem on a 50in. plasma panasonic that is 1 mo. old. the red light blinks 7 times then pauses. can't turn on, screen remains like it is off, except for the blinking red light the tv acts like it is shut off.

I have the exact same problem. I bought it June 06 and it died 2/20/09. It's out of warranty now. It was running and shut off and can't be turned on manually or with a remote. Does anyone know the estimated cost of repair for what appears via research to be a main power supply board &/or bad power supply audio board?
i have the same problem. 26 months old. it was working and now it ain't. no lights blinking. not getting any power.
Is the power LED blinking or is it completely blank? If it's blinking, how many times does it blink in a row before it pauses?
If no blink and all power sources are all good the TV's power supply may need to be replaced.
i was playing my xbox and left it on for 10 min then power net out to my room but two outlets still work and i don't smell a burning smell for my tv plz help.
