Any idea what is the problem? Can a shade tree
I have the same TV, replaced the A board, didn't fix it, replaced the P board... still didn't fix it! Tried old A board w/new P/board, no luck either.
It powers on with no display using the power button (will not respond to remote) and displays nothing. Have to hold the power button to turn it off, when I turn it on again, I get the 14 blink code...
Any suggestions what could be wrong? Did I buy a faulty replacement part?
Basically, the idea from that thread was a faulty SS board was damaging the SN boards, and replacing the SS board (and the SN board too if required) fixes the problem and prevents frying the SN board, and the A board and P board are not faulty to begin with?
The seller of the A-Board suggested this:
"disconnect the sn2 connector off the sn board and check to test if it is shorted or not with an Ohm meter. This
is a very common problem with this model television."
To be honest, I'm not even certain how to test any of these components. I think the SN and SS board were inexpensive. To do what was suggested I guess I'd hook the multimeter to different prongs of the plug on the SN board and see if there is a connection between them that shows no resistance?
so the SN2 connector does come up as shorted. I'm not sure how to interpret the resistance readings from other plug ports but none are shorted that are connected to the power board.
I ordered an SS board, I'll see if that helps. The SN board is just not available. There are SN repair kits tho-that worth trying? What is shorted on the SN board?
Greetings Impfac and 14 blinks Panasonic Plasma 2011 thread: I am in this same boat, attempting to repair a family TC-P42S30, 2011 edition. Solid red power lamp changes to 14 blinks if you hold the power button 5 secs (which I now believe maybe you should not do according to what I later learned in the flowchart pdf below). Steps I have taken so far: Without meter testing I figured power board and replaced that - no change. Then I tried a new A board on "good advice" - again, no change. Then I went ahead and carefully followed detailed troubleshooting trees in this pdf guide I happily located ->

This led me to determine I had a "Vsus" short on this board: Panasonic TXNSN1PKUU SN Board. I suspect this is a correct diagnosis because this board is out of stock in every one of about 15 sites I checked. I eventually did locate a unit misfiled at ShopJimmy and I ordered and installed this. RESULT: No change but Vsus was shorted on this replacement board too. Conclusion is ShopJimmy board had same defect so they took it back for a refund (free shipping and so forth and they were very nice and very helpful). Next up? I suppose I need to send my SN board to one of those places that claims they can repair these exact boards. We shall see. Any thread readers have any experience doing this sort of repair work? Please let me know if you get a sec. Thanks! I'll update this thread if I have more news on this sad chapter in Panasonic's miserable Plasma industry end game. (I hear they are getting out of Plasma entirely, oh well.) Cheers. ~ @kgo81
http://www.moduslinkptstvboards.com/cart.php shows that board out of stock as of Jan 22, 2014. They are offering a repair and return service which I may avail myself of. Need to sort out market for this service and success evidence, if any. Anyone have experience anywhere shipping this board out for repair and getting this TV running again?
