Re: Panasonic tc-p55gt30

There is a board that is partially behind the ss board.
I also took the back off. I couldn't wait.
There are 2 connectors not connected on a smaller psu?
I can figure where 1 goes but can't find a plug for the other.

Re: Panasonic tc-p55gt30

Lol there is a board missing.
Can someone tell me what it is? The Ysus board?

[Malachi]

Re: Panasonic tc-p55gt30

It's the Ysus sc boards. Of course can't find one on eBay.

Re: Panasonic tc-p55gt30

I kinda thought some one had been in there. Too bad that is the SC board that's missing and yes they are really hard to find. Your only hope is to keep checking sources and sometimes one pops up.

Re: Panasonic tc-p55gt30

Is there a way to check the other components? If they are ok, maybe I can sell them.

ASSUMING..this uses a TNPA5335 SC...here is one for a bit over 100... keep in mind...these are NOT easy to find whole..

Too bad that SC board is missing, literally about $20 in parts to fix. Done correctly with lock washer screws to replace the ones that affixed it before and caused the SC issue, you would have had a solid beautiful plasma that you will never want to part with.

If it was me i would put the tv into Deep storage (by which i mean where i didnt trip over it and the wife didn't nag me about it) and wait for the SC to show up.

I'd be checking the sd & su for shorts first. Seems strange the SC is missing, maybe it was still good and been sold separate? maybe they still have it? have you asked them?

[Malachi]

Re: Panasonic tc-p55gt30

They bought it as is. Seller told them it worked. How would I check the sd and su for shorts?

these are resistances I got off a set for a 50", use the gnd plate Vfg on the buffer boards.

Other way is to simply use continuity and again use the Vfg point on the buffers and slowly slide the other probe across all the pins at the ribbons.

I would do both because it's possible to have a faulty board and not have the outputs shorted which was in another thread recently. rare but it happened.

SD,

1 Vfo 4.76M
2.Vscn_f 7.79M
6. VF5V 28.1K

SU

8. Vfo 5.52 Meg
6.Vscn_f 9 meg
2. VF5V 28.4k

Re: Panasonic tc-p55gt30

I don't even know what vfo, vscn_f, vf5v and vfg mean.
I'm not a repairman. Just a guy who wants a better, TV. Sorry.
I should probably chalk it up to a lesson learned and chuck it.

you don't need to know, you need to know how to find the pins and to read and use a multimeter.

connectors are Sd46, su41, the numbers are the pins, the rest who cares and the values are what we compare to

Re: Panasonic tc-p55gt30

images, these are 50" buffers but for the purposes of identifying the pins etc, they'll do.

[Malachi]

Re: Panasonic tc-p55gt30

i can only check for continuity because without the sc board, there is no power getting to them.
I'm leaving for work. It will be later.

There's no time limit as it's night here and you can do continuity and resistances. we don't need power at all.

Point being if the buffers are stuffed it may be time to bail, if they're good then it's probably worth a SC board, just may take some time and patience to find a good buy.

[tw2005]

Re: Panasonic tc-p55gt30

Oh and if you do bail and those buffers are good I reckon you'll get more $50 back for those alone.

Re: Panasonic tc-p55gt30

Ok thanks

Re: Panasonic tc-p55gt30

Whatever you do--Dont chuck it....

Sometimes a cracked-screen same model will show up,(Try local gumtree/craigslist etc) and what you have there is a complete kit to fix!

Re: Panasonic tc-p55gt30

I don't have much storage room.
My 25 yr old son and wife moved back in. Lol.
I have found a buyer who has a board but shop jimmy lists 2 versions, according to suffix.
Since it's missing in mine, how would I know which it is?
Would either work?

[Alastair E]

Re: Panasonic tc-p55gt30

Version type generally relates to screen size, SJ should list the set it came from.

--I cant check SJ--They've banned UK IP addresses from their site.....
