Hello and thank you for the question.

This is a pretty common problem on here that we see quite frequently.

Can you tell me if there are any signs of life at all on the TV (power light lit or blinking, or a click sound when power is pressed, or the power cord is plugged in)?

Customer: replied 7 months ago.


Thanks for your help. There is absolutely no sign of life on that TV, but the power strip is alive as well as the direct tv box.

Expert:  Aric replied 7 months ago.
Thank you for the reply.

This can be caused by one of a couple of things.

Please disconnect the set from power, then press and hold the power button on the TV itself (not the remote), for 10 seconds, then release, plug the set back in, and press power once.

Let me know what happens please.

Nothing- still not on.

Expert:  Aric replied 7 months ago.

Thanks for the reply.

 

Unfortunately, there isn't a fix for this that does not require opening the TV up, and if you're still within the one year Warranty, then I would suggest contacting Panasonic and having them repair it under Warranty.

 

 

The problem is that the power board, in the TV, is not powering up at all. The quick fix is that it could be simply that one of the Ceramic Fuses on this board is blown. To access the fuse, you will need to remove the screws on the rear of the TV and remove the entire rear panel.

 

The fuses will be located on the board where the power cord connects. Please do not visually inspect these, but rather use a DMM (multi-meter) to test across the fuse for continuity. If one or more is found blown, then replace with one of the same type and rating from your local Hardware store.

If the new fuse does not cure the problem then, there is a failure on the power supply board inside the TV. Commonly the capacitors on this board will receive a surge and then fail- in which case it would be more cost effective to replace the board itself.

 

If you're looking to make this repair yourself, then you can purchase the Power Supply Board for your set at the link below:
