10 blinks error code is definitely due to a malfunctioning A-board. Since you have already replaced it, the only possibilities are
1)Either you have obtained a malfunctioning replacement OR
2)You did not get the correct revision version. Not that the same model number of the tv can use different sets of parts. That is why it is always recommended to order by part number. I have had a customer recently who had a similar problem and it turned out to be incorrect version of the replacement board. So check the part number of the replacement and the original . Also compare the revision versions of both and see if everything matches. Please let me know what you found.

SOURCE: Hi i have problem with my Panasonic TH-42PV8EY- 7

I have not repaired this model. My first thought are bad capacitors in the power supply board. If you do have the exact board to replace. I would certainly do so. Numbers check and you say they are the exact same, should be an easy fix. If this board came out of another TV of the same model, you must remember, it will have the same longevity as the board that does not work. I would compare the boards, and look for bad capacitors on the board that does not work of course. You may check the capacitors with an ESR meter (about 50 to 75 bucks). The purchase and price of one of these will pay for itself. You can fix other electronics. Thanks for asking Alan. I'll be here if you have more questions.
