HELP! PIONEER SX3800 S

samlo · 6th January 2011, 08:20 AM

Hi, everybody,---
i just got pioneer sx 3800 s receiver/amp (dead) from a friend. i repaired
its power supply, now i want to repair its power amp only. i just replaced
all small transistors. but i am confused about bios section because there is
a wire jumper fiitted in the place of D109/ D110 (in schematics D109 and
D110 = STV2 H). i dont know, what is right, a schematic or pcb? so anybody
who is familiar with this amp/circuit repairing, kindly reply in forum or e mail to shy_byz@yahoo.com. also give me some repairing tips. thanks in advance,sorry for bad english. (schematic attached)

There is no schematic attached.
I would go with the PCB as correct.
