Hi SiriusHardware

I've been pointed at that thread already by the OP from a Facebook post I made so I have already started reading that thanks and will continue to do so.

I have seen the CRT glowing so assume there is some power there and also have measured 16V DC across the voltage regulator on the motherboard so I think my power supply is good.

When you say "verified that all of the supply rails are present and at the correct voltage?" - that's the kind of level that I'm not at - how do I do that please?

My meter is a simple (cheap) B&Q meter and does not measure Hz/frequency I'm afraid. Do you have any recommendations regarding a scope? I don't think I'll need it for any other projects so one that is good value (ie cheap) would be good.

Thanks very much for the quick response.

Colin.
