Indeed.
I could mod the OPD internally to use the normal +5V rail as an alternative "power good" using a resistor.

Cracked joints on the PSU main connector, which was actually affecting every pin. The other voltages all had two pins each so they didn't show the effect.

The display is now a lot brighter, more stable and slightly taller. I think I'm going to have to open the monitor up again and adjust it now it's getting proper power.

Good stuff. Glad to hear it wasn't anything too major.
I had a weird PSU issue on my Amstrad ALT-386 and it would sometimes work and sometimes not, and it ended up being the fingers in the internal power plug being cracked. That was a bit of a sod to find.

Adapter plate for the Mean Well RT-85B power supply designed and built and the connector desoldered from the original power supply.

The new PSU arrives tomorrow but I'll be out tomorrow evening as it's my birthday and I may be out on Wednesday as well, so later in the week before I can wire things up and test.
