Panasonic projection TV does not turn on.


Power LED flashes orange 1 x 5 secs. = 1 of 3 fans stopped. TEMP LED flashes 1 x 5 secs, = Temperature error. Lamp LED flashes 1 x 5 secs. = lamp ballast error. (check lamp 1st.)
Hope this helps.

Tv turns on for a few seconds then the picture and sound turns off and the blue power light just blinks


It will do the same thing, until a repairman comes out, and services the TV set...

Symptom: No power / Dead Unit / Comes On and protects itself, Power LED may blink in 3 or 4 times cycles.

Cause: Check/Confirm SDR buffer ICs are not shorted, follow link to check. If so, replace affected SDR PWB.

That's what MY Hitachi service portal says...
Do you have one?
It's kinda like a crystal ball or magic carpet....not many people have one, but Hitachi techs do....
