I just fixed a sasmung plasma with this board. I don't know the model of th tv, as it was a basket case. And I used the only available metal back I found for it. But not correct model number. Old board was burned by one of the mosfetts and put a crator in the adjacent disk capacitor. I got a new to me, used y sustain off ebay. Tv now works perfect. Really good picture etc. Had one little line, but then I found I used a painted screw on the buffer. So swapped it out and all good.
Now the question is. One of the mosfetts on the board has a hum or buzz. Not particularity loud, can't hear when watching tv. But if it's quiet in room, then you can hear it. Almost like a old florescent light.
Any cause for concern or imminent failure? Just want to know if I should contact ebay seller and get another, hate to see it fail in a month or less.
