Re: Panasonic 42" PX-P42VT30 used kit, need help on C507

Just an update.

Got a flashing green light, 5 seconds later I heard a very small click/pop sound, switched off, TNPA5330 (S-Board) shorted again. P-Board still ok.

So there is something more wrong with my S-Board than what the standard kit (p-board/s-board) supplies.

Anyway, just thought I would inform, but I don't believe I'm going to take it further in my attempts to repair the S-Board.

Yes, the P-board is busted from the short on SC board (the components mentioned above), the 2 transistors and fuse are blown. I have the parts, just have not fixed that yet.

Question:
Don't know if you know the answer, but it appears as if the GT30 service manual puts a 16 in front of the component numbering in comparison to the 42" VT30 PCB, for example:
on 42" VT30 PCB, Q401, R401, on schematic of GT30 Q16401, R16401.

I'm asking in that I would blindly be ordering...

Just finished soldering TNPA5330 kit for VSUS short.

i.e. Q401-403, Q421-Q423, Q531, D401,D421,IC502.

Measured the VSUS line, got 60 Ohms. Turns out that C507 is shorted to 60 Ohms. Removing C507 (blue colour) from the circuit VSUS resistance jumps to 260kohm.

Either I accidently rested the soldering iron on the cap (see corner discolouration) or it was faulty.

Anyway, I need a new one. Anyone know how to read the cap value/type/voltage or where to buy it?

Pic of cap attached.

Thanks badcaps for helping me out, a huge shout out to tw2005 for his posts.

I frustrated myself by the hack method I removed IC502 (BD8693FVM) on my TNPA5330 board (Panasonic 42" VT30 from April 2011).
I have the symptoms of the blown fuse on the TNPA5390 (and transistors q300 and q301) caused by the shorting of components in TNPA5330.
Soldering on both sides of ic502 and sliding it off... and you can guess what happened. Some of the pads came off....

Hi became a member to help me with repairing Panasonic TX-P42VT30 plasma from 2011.

Surprised to see how common the issue is on Panasonic plasma that you can buy kits to repair them.
