Re: Panasonic TC-P58S2 troubleshooting

Well, I appreciate the responses this thread has gotten. I would say that I am throwing in the towel earlier than I normally might (which is why I am surrounded by half finished projects), but there are some logistical issues that make working on it painful (ie., it is at my mother-in-law's house which is a 40 mile round trip). Plus, my diagnostic tools are limted to a VOM, so getting very deep into it would be a challenge.

I wish I had had the manual before pulling the original power supply boards, might have determined that they...

Re: Panasonic TC-P58S2 troubleshooting

The maintenance manual was key. It identified the wiring harness that carries the 5v standby power from the power supply to the main ("A") board. I confirmed that the 5V was making it to the main board. Made a visual inspection of the main board front and back and can see no physical evidence of damage. No fuses on that board.

I guess I am ready at this point to assume the main board (and who knows what others) got a good dose of static electricity and is nuked. Will probably throw in the towel.

Correct, all fuses were checked with a meter, and all in good shape.

Re: Panasonic TC-P58S2 troubleshooting

Wow--that linked manual is just what I needed. This should help a lot.

Yes, I did check anything that looked like a fuse, and all were intact.

Re: Panasonic TC-P58S2 troubleshooting

Thanks for the response. Attached is a pic of the two power supply boards from a releative close-up. I can see that there are several two-pole connections that go off to supply the other parts of the TV, but none of them have any marking besides things like "P11" indicating what it connects to, but nothing more. I haven't been able to find any documentation specific to this set, so am unsure of where that standby power should be coming off the power supply.

Was hoping for a a quick and dirty resurrection resulting...

Hi all--need some feedback on my troubleshooting logic:

My mother in law received a lightning strike near her house, which fried a seemingly random mix of electronics (microwave oven, TV, computer, telephone, etc.). Most of the stuff is relatively small and cheap to replace, so I am in no hurry to tear into it. The plasma TV, though is huge, and was working fine before the lightning, so I thought I would take a poke at fixing it.

Anyway, immediately after the strike, the set showed absolutely no sign of life (I have confirmed that I am getting 120vAC to the power...

Hi all! I'm a dabbler in repairs of all kinds. I have an accumulation of appliances, TVs and computers with one problem or another, and thought I would give them the ol' college try at repair before contributing to the scrap heap.
