What board should I change
Three blinks of the power LED indicates an over-current or over-voltage condition in one of the DC supplies of the AP board. The AP board is repairable. Therefore the use of an ohmmeter and peak-hold-voltmeter is required to determine the cause of the shutdown. An over-voltage condition is definitely a defect of the AP board. An over-current condition may be due to a short circuit located in the AP board, A board, or the LCD panel.
Panasonic Viera tc-p65s2 - 7 blinks, won't turn on
I had the same problem with my Viera. if you disconnect the power and ribbon cable from the YSUS board (check youtube for how), the light led will blink 6 times, indicating the YSUS is bad. Check ebay for TNPA5175 board (about $115-160). The pop is one of the DG402RP chips burnout. These are about $4, but only available from China. If you can wait a month for delivery, you can solder the new one to replace the bad one. You may want to purchase several in case more are bad or it happens again.
Automatic screen blackout and No sounds
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.........
I HAVE A PANASONIC TH-L-32C5M THAT WAS WORKING GREAT UNTIL I EXPERIENCED A POWER OUTAGE THE OTHER MORNING. NOW, I AM NOT RECEIVING ANY RECEPTION. I CONNECT TO CABLE THROUGH THE WALL - IT IS OFFERED
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. Pull up older posts.
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.

Panasonic tx-26lxd8 Can hear sound but only a very faint picture
Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.
To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. 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.
