I suspect that you may have a power sequencing issue.

Hi Franc,
Yes I have the technical manual which, sadly, is not the service manual. And
regarding the ECO describing the 2 resistors, I've changed them. No joy.

The 502MX manual does have a section on power sequencing that is very good.
If I had such a description for this monitor (V401) I'd have known long ago
what the problem was, exactly.

Thanks,
