I want to repair the power board in my panasonic plasma tv. This part is not available as a new part and limited options for used.

Lightning-damaged electronics are a gamble to repair. Sometimes the problem is a single component, but more often multiple components are damaged, and even if you get it working, something else may die shortly thereafter. If you are lucky, only one board was damaged. My recommendation, if you have homeowner's or renter's insurance, is to put in a claim for the TV and get it replaced.

Having put forth that caveat, the blinking red LED hints that you may have enough left of the set for it to be repairable, especially given that much of a plasma set is already built to cope with high voltages. Try downloading a service manual and following the troubleshooting procedure. Here's the link (it's a Hungarian site, but there's enough English available to find things):

Try this.

Try the following troubleshooting steps.Check power cord and power outlet, possible light switch problem.
Check if you TV savy check the P board if the P board is not good check the fuses on the P board.
If the P board is OK check the A board.
To check these Unplug the TV , Disconect A5 A6 and A7 on the A board and plug the TV in and see if you get a white screen if this is the case your P board should be OK.

No training? Please stay out of the innards of a TV!
That's why they have the warning sticker on the back generally saying "No User serviceable parts inside" or similar wording.

If not recently purchased always balance the repair charge quote you'll get with the replace with new option but with this type of product I'd say if it's over 7 years old.

The tv Plasma screen panel it is 90% of the tv and it is very important to the functions for the tv watching experience.The tvs Plasma screen panels are exspensive and very limited in production by the tvs corporations only and can buy it from them only too,they'll sell the tv Plasma screen panel to u,but they'll charges u the same as a new tv.Sorry tv now only worth as a salvage tv for it eclectronic boards to used for it with other tvs only now,if the tv screen panel is broken or cracks.

10 blinks for this tv is not always an A Board issue. It can be a problem with the power board as well. A technician should look at the set to dertermine where the problem lies otherwise it is just a guessing game of inni minni miny moe.

To determine what is causing our TV to lose it's picture you would have to do some basic troubleshooting. The areas of concern for that particular model with that issue would be the Power Board, the connectors to the board, fuses on the Y & Z Boards, and so on. Once you have run the tests to determine the parts that need to be replaced you would need to find out the availability of those parts in the area that you are from. The TV is of the age that the cost of repairing it may actually be more than the cost of purchasing a brand new set. Due to downturns in the economy sales of plasma, LCD, and led TV's is much slower than anticipated. This has brought the cost of the new units dramatically.

In closing, do your troubleshooting to identify the parts that need replacing and check their cost and availability. Compare to the local cost of a new TV and that should help you to decide which way to go.

The tv can be fix about half of the price of a new one.This tv brand and model known to have alot of power supply board issues.The price about between $500-$550 Tech. replaced tv with a new refurbish power supply board replacement or troubleshooting and by replacing components parts on the power supply board.

Sorry,not repairable,because the LCD,PLasma,and DLP screen are limited produced.Replacing the tv pannel screen will cost the same as a new tv.Might even cost more after the labors.The tvs screen is about 90% of the tv,that why when is broken or damage,now it only use for it electronics boards parts,or sell for it electronics boards parts that it.

Sounds like a service code for the tv technician. Your tv has busted and now needs repair. Typical of these new tv's, especially plasmas. Your'e in luck with the Panasonic brand though. They have a large supply of parts available and will usually have a new power supply, power control board or circuit board available. Any off brand, U would have had to just throw the tv away.
