20 Most Recent Panasonic VIERA TC-P55ST50 55 in. 3D Plasma HDTV - Page 2 Questions & Answers


I presume you are unable to activate the on screen menu after the picture goes, if you can then heat for setup or initial set up and factory reset and see if that clears the problem.

My guess would be it needs a service engineer to look at it there may be a faulty part which fails shortly after power up. If by Off it is just in standby then try pulling the plug out for an hour to let it cool down then if that works do a factory reset to clear any software problems.

Hope this helps.........

Sounds like The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS].

If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

Hi Cloda,
It is mostly the power supply section which gets damaged due to power surge. In many cases the damage is repairable. Please contact some local TV tech.
Good Luck.
