Model no. F35750ST, symptom: shuts down when P1903 is connected to Audio PCB, unconnected powers up. + and - voltages OK. Orginally, HV Pulse on Collector of HOT, but no HV, and had a poping noise from the speakers. Replaced FLY, but now shutsdown without P1903 connected. Audio Output IC's bad?
Also vertical height overscan, any ideas?
Thanks
