Panasonic TH-42PX60B Hi, I had a power surge and my TV went out. I replaced the fuse in the main plug but now when I turn the TV on the Main Red LED flashes in 10 flash intervals and I cannot get a picture or anything to come up on the TV besides the flashing Red LED

there is a surge protector on the main power board this has probably blown. or the main power board fuse or plug fuse. check them one by one. there even may be a secondary fuse in the tv around 3amp witch can blow. it will have red and black lines on it or orange that is the rating of the fuse. surge protector is like a battery shap round with 2 prongs onto the board.

have you already service the main unit, or you an initial check on the parts of the TV..

kindly post back the TV model/maker..

Thank you

Try disconnecting all of your HDMI cables and plugging the power cord of the TV into another wall outlet. If this resolves the issue, you may have had a small power surge from either your wall outlet or one of your source devices. It is recommended to connect your TV to a surge protector if you haven't done so already.

Check and replace its main power regulator board. Before replacing it, check the fuse, can be located on this board itself.

Hello,

The issue you describe is consistent with a power supply board issue. This is the board where the AC goes to. This problem may have occurred as a result of irregular power supply, or excess power supply or power surge.

The TV is receiving current but cannot circulate or transfer the current to other necessary part of the TV because of the defective power supply board.

I do not think it needs replacement, rather some defective capacitors are causing this issue.
Open unit up and take a look at the power supply board.You will probably see one or more electrolytic filter capacitors that are bulged up in the top-not perfectly flat like the others.

The value of these capacitors will be different, most likely they will be somewhere around-820 to 2200uF/25 V( or /10V sometimes)

You can replace them with same values but I would recommend the voltage rating to be higher(like 35V for an original 25V) for reliability purposes.

What happens is,these bulged top capacitors will cause a low and unfiltered DC voltage=main board will malfunction(the relay will keep clicking until the caps are holding enough charge to bring the voltage up over a threshold point).

You can buy these capacitors at any Fry's or Radioshack store or you can order them online at vendors like "mcmelectronics.com"(look for electrolytic capacitors).
After replacing these capacitor(capacitors) most likely the normal operation will be restored.

Note: There may be also some other causes for this symptom ,like a defective T con board ,or main board,but the bulged top capacitors are the most common cause for this issue.

If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you. Also, note that TV stores a lot of current, so wait a while before opening the TV back cover.

I hope this helps.

Good luck....

Thanks for the quick answer. I purchased the set in 2005 and it lives outside under an overhang on my patio in humid South Florida. Unfortunately, I couldnt count the red flashes before it went completely dead. Think it was 4or 5. This would correspond with a possible fuse failure on the Power supply. I bought the online service manual, I just wish I knew what to do with it!! The fuses both seem to check out ok on a continuity check. any ideas? Thanks, Charlie

The power supply board itself maybe the main problem inside the TV. Or, it maybe something simple like a blown fuse. Replacement fuses can be found at Radio Shack or some other electronic supply store.
If it turns out the TV keeps blowing fuses, the main power supply may need to be replaced. You can find replacements at a good price at Shopjimmy.com

Replaced the sc board and tv works fine again.
