    I researched this on the internet for days and finally decided to fix it myself. You were exactly right about the problem! I was able to buy the A-board also known as Digital Video Board - TNPH0716 / ENGE6604KF online for $54.95 and this single mom that is more girlie than a princess fixed that stupid TV! Thanks a million for your help!

Hi

Thanks for using FixYa. 10 blink error in your Plasma TV means that the A Board has gone bad and should be replaced. You are right, this issue is caused due to overheating and the capacitor(s) goes bad causing these issues. You can also open the back of the unit and check the main board (A Board) first for any blown/bad components/capacitors as the board itself is around $250. Please accept the solution if the issue is resolved or post a comment for further assistance.

Thanks
Rylee

SOURCE: Panasonic TH-42PX60U plasma TV: red blinking light

are you using a PC to feed a signal or maybe a cable with an adapter?
I had the same issue when I used one of the rear HDMI ports to show a PC display. Apparently there is a software difference between the rear and side/front ports. Inputting the PC through the side HDMI port has solved the problem for me (so far!)

SOURCE: red light flashes 10 times - Panasonic TH-42PX6U

I bought this tv in August of 2008. First episode occurred in October of 2009 - after manufacturer warranty had expired. It returned back to normal. Second episode occurred in March of 2010 and never got the unit to power up.

I had an electronic service center check it out. Turns out it's a defective power unit that's misfiring. The misfire triggers the overheat error code.

Panasonic retailer wanted $575 for parts and labor.

Service center executed finely and strapped on a 6 month warranty for $375.

I will be faxing a copy of the invoice and original receipt for a reimbursement.

SOURCE: TH-42PZ80U Panasonic Plasma, red light flashes 10 times

Panasonic said "A" board,
A board SOS Detect (Explanation)
10 Blinks SOS: The voltage regulators IC5400 and IC5401 in the A board generate SUB9V and SUB5V. The 9V and 5V from these ICs are monitored by IC1100. Any abnormality on the SUB9V or SUB5V lines, triggers the shutdown circuit and the MPU shuts down the unit. The power LED blinks 10 times.

But need to measure the connection SC2, if it short, it will be the SC board.

The knowledge obtain from: Real case of repair by myself.
Information from Panasonic training manual.

Flashing RED lights in Panasonic TVs means a fatal error code. Unplug the TV, wait 1 minute and replug. If the LED still flashes it needs professional service.
