Fairly new to this. I've got a schematic for a DVD supply Im trying to fix for a friend. The schematic is available publicly so Im not concerned about post it. 90% sure its an offline flyback topology, but need some confirmation from those in the know. The unit blows the fuse on application of 110VAC which might be shorted transistors. What should I check first? I think Q912 & Q14 are the input transistors?
What is the layman definition of the "B+ switch"?
I've got a variac and scope so I could bring up slow if needed, just dont really know what to check
Thanks for any responses.
