Either a bad power supply or a bad processor board.
A Good Service Shop should know what the 10 blinks are indicating.
May be a repair cost between $200 and 400 dollars.

Perhaps an easy fix. Remove the back of the flat screen. There will be a main circuit board visible. There will be several capacitors, cylinders with a cross hatch on the silver top. Do any of them look like they have a dimple created by expansion of the internal capacitor material over heating? If you see an expanded top...that's probably your problem. Get your solder gun out and replace that capacitor. You can order a new one off of Amazon. If yours is a 10 volt capacitor, consider replacing it with a 16 volt unit. Generally the electronics companies under design the size of these units. When you replace the capacitor take note of the silver band on the unit and where its placed in the two socket holes....there is a positive and negative hole placement.

Please check these 3 boards for blown fuses, bad caps, blown/shorted components.
Power supply, Y-SUSTAIN, and Z-SUSTAIN board.
You should download any one of the PLASMA TV training manuals to learn how PLASMA TV works from the link below, it will help you to get more understanding.

First, look at the screen in darkened room to see if you can see any slight glow from the screen, if it does, then the problem can be the T-CON (not getting the 12vdc) or the main logic board not feeding the signals to the T-CON board.
if not, next place to check will be the power supply module, make sure it has 24vdc which is required by the backlight inverter to work, the reason for not having 24vdc can be from bad DC filter caps (leaking/bulging top, high ESR) or short circuits in the inverter board which will cause the 24vdc supply to go into shutdown mode, so you may have to disconnect the power cable that feed the inverter board to see if the 24vdc will work without the inverter board hookup, you will need to apply about 3~4 amp of load to the 24vdc to make sure it can handle that. There are fuses on the backlight inverter boards also. So there is some troubleshooting you will have to do to find out the causes of the problem you are having.

If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

Hello, lighting hit and my plasma Panasonic tc-42px24 will not turn on. completly dead. was told it maight be supply board??? thanks


Power surges wreck havoc with power supplies since they are first in line and bear the brunt of the rushing power. Try replacing the power supply board on the cheap by getting a used one on ebay to minimize the expenditure in case that is not it. Always a possibility,
