Question about Panasonic PT-47WXC43 47" Rear Projection Television

2 Answers

Comes on for about 3 seconds and then shuts off!

I turn the power on and it shuts off after about 2-3 seconds. I get a brief picture and then it's out. When it goes out my power indicator light blinks 3 times and pauses, blinks 3 times and pauses...so on and so on. Any ideas as to what may be causing this???

Re: Comes on for about 3 seconds and then shuts off!

My Panasonic PT has developed the same problem: The repair folk came and replaced the "entire" electronics section! The guy said it was $1500 just for the section. He had no idea what caused the problem---just that Panasonic told him to replace the entire unit. I'm delighted it was still under warranty!

Mitsubishi ws65713 picture goes out


I know these sets well, you lose brightness but still have sound?

If the green power light comes on for a few seconds and then goes out the set has a self check for error codes:

UNPLUG TV AND THEN PLUG BACK IN---TURN ON---GREEN POWER LIGHT COMES ON FOR A MOMENT AND GOES OFF.

PRESS AND HOLD "device"(input) 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

let me know what you find--hope that you find 2 blinks, a pause and two blinks--this is the most common and easiest to fix.

Brief power on then shuts off


It could be a component short or crack on the power supply board. Open the back of the TV and look for signs of defect. The power supply board is the brown one on the right with huge capacitors.

TV turns off


That sounds like a power board problem if im not mistaken where your power cord plugs into the tv there is a board it connects to often times if u plug the tv in and it starts itself or turns its self off its the power board that needs to be replaced which btw is not cheap at all

TV not staying on


If you're NOT still under warranty you should at least open the TV and look for a blown fuse near where the power cable enters the set. A lot of times you can buy replacement fuses at a local electronic or hardware store and they're easy to replace. Check the fuse. If it is blown, it will be obvious and make sure that the set is unplugged before replacing it. If it blows again, or if it is not blown, your problem is probably in the 'X' volt regulator and you will need professional help with the repairs. You can also check the board where the components are mounted and resoled any that look bad. Brief power outages may cause the TV to turn off on its own. If you are using a surge protector, try connecting the set directly to the wall outlet. In your case it could caused by a blown fuse, a leaky diodes or a bad solder joint at the horizontal drive transformer. All can be replaced at a local electronic or hardware store and they're easy to replace If this does not correct the problem, you may need to have your TV serviced. good luck!
