Hello,
It has been a while since i have been here... I love this forum but my schedule has been insane.
Anyhow, I am trying to fix a Boss BR-600 for a friend. The unit will not power up and draws quite a bit of current (much more than usual) even when powered off so it is proving difficult to troubleshoot with a scope. I am worried that if I try to scope it with power applied something will go boom.
Anyway, there is a typical issue with a small SMD 8-pin FET going bad which is used as a power switch of some sort. A quick repair online suggests removing the FET and replacing it with a single diode but without knowing exactly what this FET is doing i am a bit weary of giving this a try.
I was hoping that maybe someone would have access to a schematic for this unit???
Any help would be GREATLY appreciated!
Thanks in advance,
Matt
