Well I hate to see you give up on it. If I had done that I might have
never learned. In order to inspect the PSU properly you are going to
have to do more than just eyeball it and some voltages on a DVM. You
need to check that the voltages are within the rated tolerance and are
producing cleanly withough ripple or spikes under load.

Yes, I appreciate this - my previous report was just 20mins spent in the
shed on a Sunday evening... I have a good 'scope and will have another look
later in the week.

Once you're
certain your getting clean power from the PSU it might be time to
chuck it unless you can get replacement boards and while at it replace
the optics sled. Probably end up with enough spent to buy something
new though unless you're hell-bent on the repair and learning
something.

Yeah, quite - getting the service manual cost ~$10 (I'm in the UK) and I'm
only in the market for a sub-$100 replacement at the moment. Which is
another reason for tinkering a bit more.

I might also try to have a look at the SDRAM signals, although my my test
equipment I doubt I'll see much unless it's pretty gross. And it's probably
worth having a look at the actual video output from the Zoran - that might
give men an indication of a fault elsewhere.

Thanks again
