Default Re: What is a CSN60?

I'm glad to hear its starting to make sense. The resistance/diode test readings on the MOSFET sound like they're OK. Does the PSU have a controller chip? If you can identify a part number on it, or post a photo of the whole thing here so someone else can identify it, usually looking up the data sheet for the chip will reveal the circuit for the PSU almost exactly.

I can remember looking at the service manuals for 1970s-era Philips TV sets and discovering that many of the circuits were pretty much identical to the examples in the data sheets for the Mullard chips they used. The same frequently applies today, though the chips aren't made by Mullard any more...
