Hey everybody, I was wondering if somebody might be able to help me.
I am attempting to repair a Panasonic TH-P50UT50 plasma TV that broke due to arcing on the SS board.
I have replaced the failed components but ran into a problem when soldering the DG302 Transistor in the Q051 position. Essentially I had finished the job but when cleaning up the board I accidentally scraped away a fair chunk of the protective layers of the PCB with a toothpick - leaving a patch of exposed copper right next to my new sodder for "E" pin of the transistor.
So now I have a bridge from the "E" pin to the exposed part of the board that seems to flow out to ground (?). BUT from what I can tell from my board is that the "E" pin is supposed to be wired directly to ground anyway?
So I'm hoping that maybe somebody has an open TV lying around and would be able to test whether the Q051 transistor is actually wired to ground and I can leave the board as is without having to attempt a repair.
And if not if anybody knows how this pin should be wired.
I have included some photos to illustrate what I am talking about. The pin in question is marked with a red circle. And the purple represents the exposed area of copper that has been bridged to.
I have already tried to isolate the new sodder joint from the exposed copper by redoing the joint again but I couldn't get it to separate.
I would be so grateful if anybody was able to help me with this. Thanks so much.
