Panasonic Plasma TC P50 XI Blinks once

Re: Panasonic Plasma TC P50 XI Blinks once

I hope it's not "impolite" to bump an older thread that deals with the same problem...

I also have the Panasonic TC-P50X1 set...and all of a sudden, this past week, I get the "one blink" blink code. Everything points to the main board. TNPH0800(AB) but finding one from a reputable seller is tough...since I'm not in the biz and don't know any of the sellers.
I guess, I need to ask for recommendations on reputable places. Shopjimmy seems to be the one most recommended...but they're out of stock.

Thanks, folks.

I don't think you have many choices.

1. Ebay, two showing $110-150
2. keep an eye out for a 50C1 or 50X14 with a broken screen.
3. pack it up and send to moduslinkpts and have repaired $145 with wty

I may be a bit confused, or this may have been answered already, but I have a Panasonic TC-P50x1 as well. When I turn it on, the red indicator light stays on, then the unit power cycles around 15-20 seconds later. You can see just a plain blank backlit screen with no input signal even though I have my hdmi cable plugged in. The same thing happens with no input plugged in as well. Any thoughts?

sounding like a bad mainboard, I guess no input controls from the remote work or any OSD menus displayed?

Re: Panasonic Plasma TC P50 XI Blinks once

yea exactly, there's no menus or anything. I've done a bunch of research, and I've been led toward a bad main board or a bad su board / upper and lower buffer.

If the screen is energising and it's not shutting down off with an error blink code but just cycling it's the main board.

i don't know if it's worth the trouble but I think 1 blink is fairly common and someone has brought one back to life re capping all the can type caps on the mainboard I think? Otherwise you may have fun trying to locate a board, Modus is gone.

Is there any spotting on the bracket if the A board is removed from it's cradle? I should see if I can find this post.

I took the A Board off the cradle and didn't see any kinds of markings, "spotting" etc.

I'm looking up how to replace all the caps on this thing to see if I can bring it back to life. As well as looking for another board.

I wish I'd tagged this thread now, from memory it had spots like corrosion maybe the caps venting onto that metal cradle but I also think it had a 1 blink code. I'm looking but I've got noo keyword to nail it with, pretty sure it was 2009 era.the spots which may have been browny / red lined up with the tops of the caps.

Don't get your hopes up, could be a failed BGA device, bad solders, bad eeproms data who knows. Not a board many get to fix at component level.

Tried any freeze spray or heat the board up just in case you can fluke it to work?

Re: Panasonic Plasma TC P50 XI Blinks once

maybe send a message to these people, sounds like they know this board and it's sypmtoms which seem to be similar to yours

No picture or sound or OSD on any input but power stays on

board must be untouched for them to work on.

Re: Panasonic Plasma TC P50 XI Blinks once

There isn't any corrosion at all on the board nor the cradle/frame. All the caps look fine, no bloating or anything either. I haven't tried the freeze spray nor heating the board, though I guess I could try baking it a bit to see if that'll fluke it.

no don't bake it in case you have to pay someone to rebuild it unless you don't care if you ever get it running again, these boards are pretty non-existant.

Re: Panasonic Plasma TC P50 XI Blinks once

well after talking to my buddy who I got the tv from, he said his house had a surge, then the hdmi ports went out, but the av inputs worked.. then one day it stopped all together. heh.. looks like I'll probably have to replace the whole board (since the ebay guys say they can't repair surges) and see where I'm at with the other boards on it.

gone through it like a dose of salts, keep the board though, you never know if it will become handy.

2 faults are probably unrelated though if it kept working on AV, I blew a HDMI port from lightning, lucky just took the 1 port out

Re: Panasonic Plasma TC P50 XI Blinks once

I was going to start another thread for my problem but since it all deals with the same TC-P50X1 television, I thought I'd add my situation here.

Since February, I have had problems turning on my TV and I get the 1-Blink error. Back in February, i was able to get the TV started after cycling through the reset-power-on procedure several times. At the time, I diagnosed the problem by researching online and that's where I found the diagnostic screen and that it was probably the A-board. (reading here further confirms that).

I have determined that I have the TNPH0800AB board. I cannot find ANYONE online who has the board (or similar one) in stock. Panasonic maybe has it but I stopped looking when they listed their price at $598 USD.

Since February, our workaround has been to just leave the TV on. We would switch it to an unused input so that the screen is black and I found that the power used was minimal. This past week though, the power went out briefly (not from a surge) and I haven't been able to get the TV back on. so thus, i am back to looking for a solution.

I have found a broken TC-P50C1 on an online advertisement here in my town, but the person hasn't replied to my email. If I can get his TV for cheap, then I can put up with losing one HDMI port, but other options seem non-existent or prohibitively expensive considering that I can buy a new smart TV for $600 CAD.

If I don't get it fixed, should I just scrap the TV or gut it and sell the parts? and to whom?

Could try PTS Electronics in the US for $150USD they do rebuilds

Re: Panasonic Plasma TC P50 XI Blinks once

I could try that. When I first went there, I saw that they were out of stock and didn't notice the "repair and Return" option. Then for some reason, I was thinking it would be way too expensive to send the TV, but then I came to my senses and realized, they just wanted the board.

I'll let you know how it turns out.

P.S.: how do you get those ribbon connectors off without damaging them?
