I have a viera TC-P65S1 that is throwing a 9 blink code on the power LED. Until now I have been able to power it up by holding the power button for around 10 seconds but it isn't working anymore. From what I can find online, there's a problem with the A board. Is this something I can change with average mechanical and electrical skills? Could it be just a firmware problem?

I've resurrected a lot of gear by replacing bad capacitors. I was looking on badcaps.net and someone said they "After replacing those stressed 'lytics," - your Panasonic model - all the high Voltage primaries - it still didn't work. But those weren't the bad caps. I've only seen ONE switching power supply that lost a high Voltage cap. The vast majority are in the control loop and the output caps. Often they are bulging but not always. If they ARE bulging they need to go. I've seen no surface mount caps that bulged but LOTS (LOTS!!) of bad ones. They are THE WORST for failing but are some of the easiest to replace. I use a cutter with a very thin nose and cut them out. Do NOT cut at the bottom as you'll tear off the pads. Cut the cap at the seal crimp point and then remove the seal disc. Then clip off the wide part of the leads, remove the plastic base and un-solder the old flat leads..







Make sure you buy GOOD caps, not the everyday junk at the local supplier. Particularly for switching supplies, you want high ripple current (low ESR) and long life units. DigiKey's online catalog is easy to deal with and I buy LOTS of caps for work. Mouser is another good source.







Take pictures so you can get it re-assembled as it was.

We bought the TV from Best Buy. Extended warranty expired 1.5 years ago. From what I found online, the A board is bad. This is where the input wires plug into. I'm not sure where to buy it from without getting ripped off. Can someone point me in the right direction please? Geek squad price is $350 for the part plus $150 labor.



Also a way to look up the part number and price of the part would be a huge help.



Thanks! Rich

TV is working again! I found the Main (A) board online for $229 which includes a $50 refund when I return the bad one. So net cost with shipping is around $190. I was amazed how scarce this board is for a 4 year old TV. Just about everyone was out of stock. I assume these are refurbs too. I plan to get another one to have as a spare as it seems this is a common issue with this model.
