TNPA5105 SC Repair KITS.

[tw2005]

Thought I'd throw this up in case anyone gets interested at self repair.

Just some kits getting around of varying degrees of completeness.

Only one you can see is OEM supplied components 10pce kit, 13pce kit interesting the extra 3 parts adds 100GBP?, nice copycat ad as well and another larger 17pce kit.

10pce

looking familiar

13pce, the price is absurd. States OEM, photo and description mismatch? Then in the body of the listing it says for repair of your board "the cost for this service is £89 for parts and labour"

Easy, have them repair it and save 40-50GBP! Something's wrong there?

This one is more complete, 17pce

Some info but anyone fixing could use most of the TNPA5081 items listed as a good guide to what can fail.

Q621 ? will be something in spec close to a 30F125

The TNPA5105 is a cut down version of the 5081 which I repaired.

Not all of the transistors are identical but will be similar in rating, you'd have to compare the OEM numbers to figure it out more.

The big list I created for the 5081. Unlikely you'll find this much blown.

Re: TNPA5105 SC Repair KITS.

Reported successful repair on TNPA5105 for a 54", D451,RF101L4S 400V 1A had to be replaced also, first test failed.

Repaired,working

Re: TNPA5105 SC Repair KITS.

Hi tw 2005
I have been looking throughthe threads on TNPA5081, since the board is no longer available in Oz through Panasonic.
Generaly I shy away from repairs where parts have blown on a board all over the place instead of just one bank of transistors, have to admire your persistance on these boards.

Unfortunatly I have to now try to fix one or two of the SC boards. where is the best place of getting all the parts in one hit, or is it better to just get a kit, some seem to have most of the stuff required, driver ICs smd resistors , FETS etc from UK.

Re: TNPA5105 SC Repair KITS.

UTSOURCE is where I go for all the bits. Maybe got some resistors from RS and a TI sub for the toshiba schmitt inverter there too.

To be honest some of the IGBTs seemed recycled but I did not care because what I got and used worked.
ALIEXPRESS I read of someone using that but not real sure otherwise. OF course you could getthem from Panasonic which would make it very expensive and would put the pressure on to get it correct or $$$ up in smoke.

kits are marked up a bit but the GTV watford ones have oem new components. I would expect that to be the most complete kit. The shopjimmy ones unless they have corrected a deficiency in those are a good price but postage is not great.

Don't fall into the trap of trusting the kit will 100% repair the board. I know of someone who tried the SJ kit and they all blew again because there were a couple of key components not included which I would expect to see.

Re: TNPA5105 SC Repair KITS.

Thanks tw2005, I did end up ordering from utsource, getting enough parts to do a few boards, they have everything except one transistor so lets see. Would be good to find out why all the parts blow in the first place, Panasonic would know and should put out a rebuild advice if they are unwilling to supply complete boards now for some times only 3 year old TVs.

Which transistor?

I wonder where the law stands? 3 years is still too young for the money they cost in 2010.

Is it a 5105 or 5081 you're doing?

Re: TNPA5105 SC Repair KITS.

couldnt get the Q16702 transistors, anyway all the other parts arrived and I have found more dead stuff. Im rebuilding 2 boards at onece TNPA5081 for a 50"
and one for 54" set which I had lying around after replace ment. Seriously should have written the last set off though,

Re: TNPA5105 SC Repair KITS.

Found a faulty SC board in my pile of dead parts out of an THP50G10, this has many sections and even the location numbers the same, and am currently canabalising this for the remaining parts. See how this ends up soon.

If you're doing a 5081, do me a favour and put the results in the 5081 thread.

A list of what IGBTs you found shorted?

As for Q702 2PD601ART, I had no trouble, just placed an order and it's on it's way. But it's just a GP NPN transistor so not too hard to sub for it.

I used BC846 only because jaycar was handy.

These boards are scarce too, only way to get one in most cases is to find a component repairer.

Re: TNPA5105 SC Repair KITS.

Anyone have the schematic I cant find it on google ??

My board is a bit more complex, following parts some are not included in repair kits are dead:

Q451
D482
Q422
Q421
D402
D401
Q402
Q401
D422
Q660
Q661
IC521
R421
R422
R551
R506

If any one has the PN or schematic to help me find what parts I need I will be very grateful.
