Oh yes, I'm game.
I've dabbled in fixing plasma tv's and such, and am always up for learning something new. Also, I very much appreciate your help in this!
I could not find the exact transistors, so I found ones with the same characteristics. - I hope this is not a no no, I've had luck doing this before.
The parts I've replaced are:
Power Amp:
Q325,326 -Replaced with NPN FJA4313
Q327,328 -Replaced with PNP FJA4213
Pre Drive:
Q318 -Replaced with NPN 2SC2705; was 2SC2631
Drive:
Q322 -Replaced with NPN 2SC5171; was 2SC2592
Q324 -Replaced with PNP 2SA1930; was 2SA1112
Diodes D316,322 -Replaced with 20A91 and D326 -the the series fix
Thermistor TH302 and resistor R358.
Q318 and R358 were visually burnt.
How would you like me to send you the schematic?
