Yeah ok. I guess that's where it's good to start your own thread on different models. I was thinking you were talking about a gt.

True... You're right.
Then somebody please split the topic, from my fist post with the name "Panasonic Plasma TX-P50GW30 - 7 blinks"

OK then, if the 5351AC is from a 46" model, then this means it's not the original one from my TV, and it was replaced; very possible... still, the good one that I have, wich is a 5351AF, that I'm sure is from a 50U30, will be able to resist on my tv? I left the TV ON with it 5-7 minutes, and it was still cold.

who know's, without the manual a bit of a guess. just googled the model and there's an AB version saying it's from that which is a bit of an oddball with the full sized heatsinks suggesting it's a thicker chassis.

the AF is in our 50U30




doing a bit more digging and could be some wrong info out there as I clicked on a link stating AC for the 46 and then found it was an AG pictured

AC looks similar to the AB

In this case I'll install the missing parts and heatsinks to the AF board...
The AD board looks identical with this AB model;

Job done...
I've installed the missing parts to the working board, and everything works perfect.
On my original board I think it was the IC921 faulty, but I'm not so sure, so it was better to complete the working board than moving the IC921 to do more tests...

First time i installed the kit, it fired up and worked beautifully for a full length movie. At the end of the movie, the board died again...and now need to buy another repair kit plus the Q621 and Q622. When I replaced these, still 7 blinks. Used multimeter to test Q661 and found short. So only thing left to do is change that transistor. The part is being ordered now.

Working beautifully now after replacing the Q661.

Added a few heatsinks to the transistors and diodes to prevent it from blowing up again. Then screwed the back panel on.
