Linn 9000 Power Supply

I’m in the enviable situation of finding a couple of Linn 9000. The power supply has gone on one so thought I’d upgrade it with a Mean Well RT65B. Connected it all today and it all seems to power up except there is no display, changed it to the other that works and its the same, power but no display.
Any ideas?


Update to this.
PS is fine and machine 2 is working like a charm, I forgot to connect the display.
Having swapped the old PS to machine 1 this is defo bad, it powers on ok and display works but figure it must be the system eproms that have gone :thinking:
