Panasonic TC-P46S1

[splitcrete]

I just need to know if it is worth $50.00 USD for this TV
It has a 7 blink code, and the owner knows it.
Thanks for reply.

Re: Panasonic TC-P46S1

Repairable but can be an involved job, something like 10 IGBTs to replace on the SC board. Not bad though, great TV when working. $50 sounds about right.

Re: Panasonic TC-P46S1

I have the TV , and just opened the bonnet . Some pictures in A minute.

Re: Panasonic TC-P46S1

what one is the SC board ?

Re: Panasonic TC-P46S1

I found it going to start de soldering now . I have the famous atlas DCA model DCA55 made by you blokes. lol

Re: Panasonic TC-P46S1

Had to stop, I don't know how the connectors for the flat cables, disconnect.

Re: Panasonic TC-P46S1

Any one know if the burnt one in red is the same as the one in blue?

Re: Panasonic TC-P46S1

better picture

Re: Panasonic TC-P46S1

Did some home work, they are the same... B1HFPFA00001 TRANSISTOR ... Hope this helps anyone with the same burnt spot.

Re: Panasonic TC-P46S1

Going to order a couple and try to solder back on board. The pads are just about hanging on. The IGBTs check out all right, no open or short. Just hope I get lucky for once.

Re: Panasonic TC-P46S1

Replacing that FET driver might be a good idea too. Unusual to have only 1 blown part and no shorted IGBTs.

I guess you've worked out the part number doing a search.

HOMBRE did manage to get his TBPA4782 going eventually

Re: Panasonic TC-P46S1

Ordered the parts now to wait. Going to clean pad area today to get it ready for transplant. I will post back with results.
Thanks for the reply all .

Re: Panasonic TC-P46S1

I bought a kit from Shop Jimmy and it is very big kit over 30 parts.
I changed all the fets the fet drivers some diodes .Etc .
My question now is about the burned part in my first picture.
I soldered wires to the pins of the part and now I have to make sure I
traced the tracers right.

Re: Panasonic TC-P46S1

Here is where I think to solder the wires to.

Re: Panasonic TC-P46S1

see if this enlarged image helps to confirm the traces.

Re: Panasonic TC-P46S1

Thank You tw that helped me out so much.
I almost bridged r516 and r517 . Almost done with this beast.
If Q521 wasn't blasted off the board I think it would have been just a re work job.
Tomorrow I will solder Q521 in and turn her on.
Thanks again

How clean is the board? All that carbon conducts. How exactly are you going to mount the new transistor?

Any info from the kit can you post up like part numbers/locations covered? Who's kit is this?

Re: Panasonic TC-P46S1

I have been trying to solder thin wires to the transistor,
but it is so small. Any ideas ? The board had a crater where it was once soldered.
I can't do a trade in because the board is damaged. What now ?

Re: Panasonic TC-P46S1

Shouldn't be too bad, I wouldn't be buying a new board at that point... I attached a picture where you need to wire everything (confirm yourself before doing it)
Just use some very thing wire and scrape soldermask off from the places where you solder them.
Make sure you clean all that carbon residue thoroughly off before doing anything
