Re: Totally Dead TC-P50S30 Panasonic Plasma

Thanx for the manuall

Re: Totally Dead TC-P50S30 Panasonic Plasma

Ok, found the A6 connector..

Pin 6, meter on AC, no voltage...

Meter on DC 4.99V

You need to pay attention, I did say DC and earlier someone had also said AC for the mains and you had it set DC. Having meters set wrong can blow the meter and blow whatever you are measuring.

better get the MRS to push 1 now(joke)

last step and this is in that guide, unplug the tv(or turn mains off at wall) locate A1 and disconnect, plug TV in , mains on but not turn TV on, do the relays click? If No A board

look at page 33 in 2011 guide, not exact model but similar procedures and setup for this bit anyway.
i expect it will still be dead

Re: Totally Dead TC-P50S30 Panasonic Plasma

Sorry about that.. I'll pay closer attention..

OK, I unplugged the TV, disconnected the A1 connector..

Plugged the TV in.

No Clicks, no nuttin...

The A Board it is...

Thanx a bunch for the assist.. I really appreciate it...

Are there guides like that one you posted for all TVs?? That would be really helpful...

not all but a good selection for panasonic, tom has a sticky and links to his collection

Since it was a lightning hit, maybe take the A board and have a close look top and bottom. I have had lightning take out the HDMI and Tom just had one that was dead and on the back all the HDMI ports were destroyed. I think from memoryit shorted the analog ASIC ( custom ) IC that deals with the standby/startup voltages etc. I think IC5000 on yours. It;s possible something is killing the 3.3V which goes to the front LED and also the processor and other voltage which then activates the relays for about 15secs at plug in.

have a read, the guide gives a bit of a description. You need to identify the board and the revison to get the correct one for your model, manual should have the part number and also on the board.

If in doubt ask or confirm here, Moduslinkpts do repairs but you may find one fro Shopjimmy or Ebay etc, payless components.



My eyes are screaming for sleep.

Re: Totally Dead TC-P50S30 Panasonic Plasma

Found an A-Board on Ebay..

http://www.ebay.com/itm/PANASONIC-TC...item2c906d42b9

That one is a TNPH0914 1A and then one in my set is a TNPH0914 2A..

Physically, they are almost identical.. An extra connector up by the A6 connector.. And 2 USB (??) on the side that mine doesn't have...

But all the connections seem to line up OK...

Think it will work???

No, you can't use the 42" A board in the 50" sets. Unless you're prepared to swap the panel control flash chip over.

[Michale32086]

Re: Totally Dead TC-P50S30 Panasonic Plasma

Which I am definitely not prepared to do.

Thanx Tom.. Just saved me from myself..

[tw2005]

Re: Totally Dead TC-P50S30 Panasonic Plasma

TNPH0914AC, TNPH0914AK,TXN/A1PHUUS according to Shopjimmy

second picture on that ebay you can see the revision suffix legend you need to locate and confirm what revision yours is

Re: Totally Dead TC-P50S30 Panasonic Plasma

Just an update on this...

A BadCaps user had turned me on to a set of parts for this TV with an A-Board I needed. Unknown operability so I picked up the lot for $25...

Got the part in and it turns out that the A-Board, the board I needed had the Button Connector ripped off.. I took the connector from the old board, had to rebuild a couple traces..

And.. VIOLA'!! It works!!!

Many thanx for all the assist....

Good News, thanks to these posts I have fixed my TV and I wanted to share how east it was. So I have a PANASONIC TC-P50S30. Reading on here about the bad ground with the burn marks I found a pretty bad one on the SS board so I cleaned all the screw mount with my dremal wire brush. It was so bad it melted the solder on the board so I added some new solder. Then I screwed them down good. TV still did not work. Nothing, no power, no light, no flashing and no power from the power board except the standby. I was about to give up, I was sure I had a bad main board ($100.00) But I decided to read more and someone said to check the buttons. Sure enough it was bad, these buttons are the cheap type they used to use in Atari joysticks, junk! So I used a screw to push the power button and presto, my TV works. Awesome. Just as simple as that? WOW! I say the power button is guaranteed to fail without a doubt because of its design so check it!

In the picture I provided you can see the power button is broken.

I could not find the button panel but I did find the SMD buttons on eBay.

Thank you everyone on Bad Caps, thank you so much!
I also got a big bruise on my leg today because another heavy TV fell on me.

yeah , that's a new one for a fault. Hope you paid attention to the SC board too then for burns, loose screws and bad earth. That's normally what blows and shorts out.

Re: Totally Dead TC-P50S30 Panasonic Plasma

OH YEA! I checked under all the boards. Brushed them all up nice and clean. I only found the 1 spot under the top right side of the TV (SS Board) viewing it from the back with the cover off. Then I found the bad power button.

You need to pay attention, I did say DC and earlier someone had also said AC for the mains and you had it set DC. Having meters set wrong can blow the meter and blow whatever you are measuring.

better get the MRS to push 1 now(joke)

That wont happen on any Fluke or Agilent DMM. Nothing happens to any of the DMM's of these 2 brands, if the meter is set wrong on the dial. They also advertise that as one of the reasons.
