Turns itself off after about 10 minutes of watching, then Blue Power Button Light starts blinking. Unplug and replug and then it will turn itself off again. Please Help my JVC AV-48P575 48 in. Rear Projection

dead power board

need the model number of the panasonic and also how many times it is blinking. The blinking is an error code.

Unplug replug about an hour later,if the same problem than ur backlight video board it dead.Need it replaced.

Here is what you do:
UNPLUG TV AND THEN PLUG BACK IN---TURN ON---GREEN POWER LIGHT COMES ON FOR A MOMENT AND GOES OFF.

PRESS AND HOLD “device” and “menu” buttons on front of tv for at least 5 seconds and then release both together.


Watch for power light to blink in a sequence:

1 blink-then 2 blinks-------no error

2 blink-then 1 blink-------X-ray protection

2 blink-then 2 blink-------SHORT PROTECTION*******

2 blink-then 3 blink---------deflection circuit problem

2 blink-then 4 blink---------vertical circuit problem


******2, then 2 is most common---usually means one of the fuses that protect the Convergence IC or IC’s is blown---set will detect no voltage to convergence IC and shut down.


SET WILL REPEAT BLINK ERROR CODE UP TO 5 TIMES AND THEN TO GET IT TO REPEAT MORE YOU HAVE TO UNPLUG SET AND TRY TO TURN ON AGAIN.


IF IT IS 2 AND THEN 2---USUALLY
CONVERGENCE CIRCUIT PROBLEM

Power supply is the place to look, look for bulging on top of the capacitors in the secondary side of the main power supply.

Yup, it seems a lamp problem can give a blinking green light over the 10 times (1 - 10 times for diagnostic codes), but in my case rather than replace the bulb if it works for a minute then resets with the green light blinking, do what I did.
Take the lamp out and inspect it, it has breather screens top and bottom, if it cant breath because there clogged with dust, clean them, and you can remove the screens, use q-tips and clean the inside. I saved the cost of a lamp and it's working fine!

Good Day,lizbg;
Check the solder connections at the negative side of both C809 and C810. Resolder if necessary. This a common problem with model.
Good Luck, Big Irish.
