Currently working on a DVD PSU, does not seem to complex a PSU but the low voltage & high voltage are linked by an optocoupler & it got me thinking, what data is this optocoupler passing between the 2 parts of the board? I know the basic function of an optocoupler & why they are used but I'm trying to understand its function in this PSU.
I might need some assistance in repairing this PSU so I'll post another thread in the correct section when I get some time to look at it
