I had a similar problem with my Hisense TV and I replaced the "Main Board". Got the part on ebay. Don't know if this will help.

Good luck!

Hi.
I see this all the time.

What you have is capacitor failure.

Sometimes with flat screen tv's, the capacitors will give out without notice.
They will be good one minute, and give out the next.

Unfortunately, this can be an expensive thing to repair.

This is due to the tv's requiring special capacitors to power the system properly.

I don't know how many capacitors are burnt out, so I can't give you an estimate as to repair costs.

I do know, however, that it can sometimes be more cost effective to purchase a new tv rather than have repairs done to an older tv.

There are 2 companies that have specialists trained to do this repair work: Fry's, and BestBuy.

I would take it to whichever is closest, and get an estimate, that way you can decide if it is cost effective to do repairs, or if you should just get a new one.

I know this wasn't what you were expecting, but sadly it's the way it is.

All of these tv's failing is because they made a ton of the capacitors back in the 1990's, and they were almost all junk.
Then the parts sat on shelves for 5, 10, 15 years, and then when someone got a repair done, they got the old parts.

The tv industry didn't correct the problem until June of 2010, so any tv made before that has the potential for capacitor failure.

Capacitors for tv's are supposed to last around 25-30 years, but all these junky ones that were made had around 18 months to 7 years as their life expectancy.

I hope this has cleared things up for you, and that it helped you out some today.

Good luck to you.

SOURCE: panasonic Tc-p42x1 picture is good ,but no sound,

First reset to default, if don't work look for firmware upgrade, then make sure speakers are set to on.Actually there is always digital audio output when there is any TV input. However when the digital TV is used, digital bitstream format is output (for 5.1 channel sound). When any other TV input is used, digital PCM format is output. This is normal and indicated in the owner's manual.
Set the receiving decoder in the stereo system setup menu (not the TV) to automatic digital audio detection, not PCM or bitstream. This will enable digital audio when any TV input is selected

Panasonic TC-P42X1 acts like it is turning on, the screen turns black, then the tv shuts itself off and back on again.


Rule out any loose contacts in power outlet, RC Jack, cables and connectors. The problem described by you calls for opening the back cover and further investigation, which should only be done by a qualified service technician.

No, it is definitely not worth repairing. The panel is shot and you can buy a new lcd tv for less than the repair.
