Panasonic TC-P54 Doornail Dead

Re: Panasonic TC-P54 Doornail Dead

any g20/g25 should be able to plug in and at least see if the stdby led and relay clicks, could turn it on but picture will be wrong but at least confirms A board

Might be worth it to run into town and take a look... If I don't have one, I can order one and have it here by Fri in time for the weekend..

Re: Panasonic TC-P54 Doornail Dead

Nope.. No shorts on P2 or or P11 or SC2.




Yep, dead TV, 5v STBY is present, no relay clicks, no LED...

A Board it is...

Not the best news in the world, but at least it IS news.

Thanx

looking scarce and expensive. If it's a g20 about $136, $150 G 25 for modus repair.

only other option, find the cheapest TNPH0834 for whatever sreies it is (g20, G25) and do a swap of the eeproms to convert the donor board to the correct configuration of a 54". would have to do some research through the manuals to figure out which eeproms are different. (do first before jumping )

Re: Panasonic TC-P54 Doornail Dead

Yea, $150 is borderline for economic viability. Puts the total outlay to $200 but likely would only sell it for $300...

On the other hand, I got picked clean this weekend on all my TVs (except a crappy RCA DLP) so I need the unit..

Hopefully, I'll have a compatible board flying around my shop...

Might be one to put asisde and hope what you need pops up. good used working SC is worth more than the $50 you spent.

Re: Panasonic TC-P54 Doornail Dead

Yea, I hear ya... If I didn't need the inventory so bad, I would just shelve it and wait til one comes in with a shattered display.. I average about 5-10 busted TVs a week so one is bound to turn up..

On the other hand, the vast majority of what I get in is <50" so the chances of a 54" coming in is not so great...

We'll see what secrets my shop holds.

Re: Panasonic TC-P54 Doornail Dead

Well, I thought I was born under a lucky sign..

Found a Panasonic TC-P42X5..

Unfortunately, the A Board is considerably different..

But might it be used just for testing purposes??

[Michale32086]

Re: Panasonic TC-P54 Doornail Dead

For the record, this unit is a TC-P54S2

Disregard.. Stoopid question. Doesn't even come close to being compatible..

Gonna take the plunge and get a replacement board..

I found a TNPH0834 for $50, a third of the cost..

The eeprom solution might be a better option...

I forgot there was a S2 in the 54, A board is TNPH0831AD in that case

[Michale32086]

Re: Panasonic TC-P54 Doornail Dead

Yea, that board is harder to find..

[Michale32086]

Re: Panasonic TC-P54 Doornail Dead

I am thinking I am going to get the TNPH0834. Once I confirm operability, then I can search around for a TC-P54S2 eeprom

not sure how you'll go with that. The p boards are the same but at A7 there is a difference with pin 8 not used in the S2 but is in the G20/25.

the A7 connector on both is the same but i would expect the cable itself to be missing on pin 8

the a6 connector is the same, have not checked the pins used

The A1 is different, 8 pin on s2, 7 pin on G20. so cabling won't plug in directly, pins used are the same though.

and then we have the eeproms, nothing I can see lines up.

seems like a real hassle.

Re: Panasonic TC-P54 Doornail Dead

Yea, I see your point...

Before I found out that I would need the AD board, I was looking at this one:

http://www.ebay.com/itm/281595598057...%3AMEBIDX%3AIT

It doesn't have any XX designation and I have emailed the seller to get a closeup of the resistor-grid/designation area...

As I see it, that board is pretty much my only hope. Otherwise, I just shelve the unit and wait...

I think I worked that out to be a 42" plus either he's selling an A board or some samsung part depending on which part of that ad is correct.

You're not really saving anything significant when a repair is $142

Yea, the listing is kind of confusing.. Hopefully if he sends me a pic of the area requested that will clear it up..

I came across one of your comments here....

with a link to ModusLink PTS..

That shows some promise as well..

Would you recommend them for the repair if I opt that route???

i make plenty of remarks, all opinion really but everything I 've read about moduslink seems ok, including the odd failed repair. there's been a few posts about A board repairs being ok.

never used them, i can't but I'd be confident.

serious investment for small return if only $300 sell, selling sc/sd/su as a package may yield $150 they are getting scarce. not as glamorous as getting it running again but same profit potentially unless the $300 is conservative

It is. Being that this is Tax Refund time around here, I have been getting a little more for the TVs I sell..

I have also thought very seriously about just doing parts thru EBAY.. As I mention I get 5-10 Units a week in various stages of (dis)repair. I could have a pretty decent Parts House business going..

But, beyond the fact that I really like repairing TVs (I do laptops and pooters too) I really don't like dealing with EBAY.. As a buyer, I have had 99.9% good experiences on Ebay. As a seller?? Tried it and it sucked..

Also, when I was doing both concurrently (selling parts on EBAY and repairing in my shop) I had found that, more often then not, I would sell a part on Ebay one week and the next week I would NEED that part..

Thanx for all the help and advice.. Guess I'll sit on it and percolate for a few days and see if any new developments shake loose..

I think so, a 54" is a good size. I've had parts for a 50vt20 (3d)for almost 2 years hoping for something to surface, and this week something has, hopefully I can snap it for a good price. Not really interested in 3D much but should make it more attractive to sell.

A board faults are hard to get out of cheaply now with boards hard to find.

If only it was a g20.

Re: Panasonic TC-P54 Doornail Dead

Yea.. Not counting a couple 60" DLPs, a 54" is the largest I have come across for my shop.. I did get a schweet 60" Samsung Smart 3D, but that was for my home and was, shall we say, also not a smooth sailer..

But the large ones move pretty quick this time of the year. So, hopefully something shakes loose soon..

Thanx again.. As always, I learned a lot..
