I would replace the electrolytic capacitors in the power supply before going further.

Hi,
After a few years I wanted to try my Cube with the soundbox/VGA splitter
configuration for the first time. (I have the fading phosphor N4000A so
have been keen to have an alternate video solution.)
However, all is not well. Using the keyboard power button, the machine
powers on for a couple of seconds, just long enough to see a NeXT logo
and grey desktop on the VGA (yay!) but then powers itself off again.
I did the obvious thing and tested it with a standard monitor and cable and everything is
okay. So the problem must exist with the splitter/soundbox setup. Soft power signals?
Any suggestions welcome.

Any clues?
Thanks in advance
