I've got a Sony STR-DN1060 which blew one of the FL channel transistors the other week. I've replaced the pair and the matched double ceramic resistor. Put it back together and I'm still getting a protector error after about 10s.
I have the schematics for it. I've stripped it back down (repeatedly) and checked the resistances across the resitors in the current detector circuit on that channel (R1700-R1719), all look ok. I've checked the fuses (all OK), and D1700 and 1701, also check OK.
Any ideas for where to go next please?
