Hi,

It's the problem of overheating in the power supply board of the TV.on the power supply board of the tv there are few capacitors and IC.any of this ic is got short or may be weak.so due to this when you start the TV the current passes from electric outlet to the power supply board of TV.but when the current passes from that weak/faulty part at that time current gets stopped or slow and the board overheats and TV shuts off. this is a common problem faced by many other users too.the possible option to solve this issue is to check the power supply board by a meter and continuity tester and replace the faulty component on the board which is short due to which power supply board is getting overheated.its bit technical job but yes its not at all a costly repair to do or get it done by the technician. for required parts it can be easily available from local electronic hardware shop.
Good luck in solving the problem...

Do you know how to use a meter? If so the first thing to do is take the back off and check the AC fuse, if this is blown replace it and see if the set works. If it blows again you have a short in the primary power supply and replacement of the power board will be required. If the ac fuse is good you will need to check all the plugs coming out of the power supply for voltage, if you have voltage coming out then you could have a bad main board or power supply. If you have no voltage coming out and the fuse is good then replacing the power supply is required. Let me know what you find and I can help you further!

It could have blown the internal glass fuse/s on the power supply otherwise its a component on the power supply board. Failing that it would have to be in fornt of me lol. Good luck.

Panasonic HDTV issue


A high pitch whine is typically the sign of a short. Its the switching power supply turning on and off at a fast rate and your hearing the unit "whine" because of the fast pace it does this at. Best bet is to have a tech troubleshoot it.
