Re: Panasonic TC-P42C2 powerless

Update: I purchased the "A board for my plasma 42" TC-P42C2. My tv now works perfect. I got it from eBay via shopjimmy for $94. The panasonic part number for the "A board" is TXN/A1LFUUS. My tv was showing no signs of power. No led illumination, tv would not come on whether using remote or power button on tv itself. Hope this helps some one else. FYI: in my case it was not necessary to purchase the power board even though there was no signs of power.

Re: Panasonic TC-P42C2 powerless

Thank you so much. I already looked at eBay before I asked you that. I initially thought The fix would of been the replace the power board , NOAB6Jk00001. That costs $39 new on eBay. I will order the av board first, then the power board. I will post my results. Thanks so much!

Georgian26, I purchased the board off of Ebay, (I just looked and there weren't any listed....keep checking ya never know).
You can also check ShopJimmy (just did and it's close to 100 bucks). Or just do an internet search for it.

Trust me, when I am playing around in the back of a tv I treat it like a loaded gun.

It's very kind of you to post the solution to your problem; it may very well help someone and save them some money.

I am very happy that you got you're set running; I love my Panny plasma.

PLEASE don't take this the wrong way, but I'd still caution anyone against messing around inside of of TV. Even unplugged, there's enough current inside to kill you if you don't know what you're doing.

Re: Panasonic TC-P42C2 powerless

Update on my Panasonic TC-P42C2 42" plasma. Did some research, talked to some people off the forum pages.

After learning the basics on checking voltages....my power board was fine.

Turns out the issue was the AV board (part # TNPH0831A).

Hope this helps someone else out.

Re: Panasonic TC-P42C2 powerless

Thanks WG,

I have unplugged and turned the tv on at least 4 to 5 times throughout my simple diagnosis....nothing.

I talked to a guy on Ebay who was selling the replacement switch and he said the same thing you did about it being a "soft" switch. He told me to check continuity with my meter by pressing the on button with my leeds on the plug...it checked out fine.

I was hoping to find something on the pb that was wrong and replace it. I ended up ordering a power board for it off Ebay. Will give an update when it arrives.
