Hi Dan. Thanks for...
Hi Dan. Thanks for your service! I have a Panasonic TC P42c2 TV that will not turn on. A relay clicks then clicks again a few seconds later. The power light flashes continuosly one second on then three seconds off. I replaced the power board but the results are the same. The TV is 3 years old but probably has less than 100 hours of on time. Any thoughts on what I could try next?

Dan here! I'm sorry you were having trouble with the system. I'll do my best to take care of you from this point, OK?

Do you have a meter? What's the part number on the board you installed?


Thanks,
Dan

yes I have a meter. P/n NOAB6JK00001

OK, reference the diagram below. Please disconnect the power cord, then disconnect the SN board from the P board. Then reconnect the power cord, and try to turn the TV on. Let me know if the symptoms change at all.

already did that. no change.

Sorry to repeat procedures. Can you tell me everything you've done, so we don't redouble efforts?

Following disconnected from each other one at a time with same result:
P-SN


SN-SS


P-SS


I then disconnected both cables from P to A and got no click/no red power light at all.


After I re -connected those, I disconnected the speakers -same result.


I also disconnected the push button power switch.-same result.

What voltages are you getting out of the P-board when you press the power button? Is VSUS active? 15V?



Dan

it jumps around but 150-190vdc

Sounds like your P-board is working just fine. Have you replaced the A-board? That's the next logical defect based on the symptoms.


Dan

No I haven't. It will take a couple of days to get it if I can find one. Sounds like I'll have to determine the "suffix" for the P/N. Any suggestions where to find one?

I like ShopJimmy.com and TristateModule.com for used/refurbished parts. Both are very good. Suffixes won't matter... they're just revisions of the same core board. Match suffix if you can, but it's not a big deal.

Replace the A-board. That's what I would do in this scenario.

I hope that answers your question. If it does, please remember to rate the service I provided by clicking a smiley face, then "Submit." Don't worry, that won't close your question... you can come back whenever you want for more information. Now, if this didn't answer your question, just click "Reply to Expert" and let me know!

Best,
Dan

I replaced the "A" board as you suggested. TV works fine now. The board was pretty hard to find. Couldn't find a used one. Most vendors had not had one in stock for months. Got one for $202 after return core charge. Thanks again. I'll ask for you next time!


 


Ken

Hi Ken,

I'm happy to hear the TV is up and running! That's really excellent news!

$202 is pricey, you're right, but it's definitely better than a new TV! I'm happy to help in the future, just let me know.


Best,
Dan
