My MicroVAX 3400 will not power up. I think it is because the right hand
H7868 PSU has failed, the green LED on it does not light up, while on the
left hand H7868 it the green LED does come on. I have no real electronics
expertise, very limited diagnostic equipment (just a multimeter really) and
I know that fiddling with PSUs is one of the more dangerous things you can
do with a computer. That said, I am willing to have a go at repairing it,
but have no idea what might be wrong. All I can say is that it worked a few
weeks ago when I last powered it on, but when I came to power it on tonight
it was just dead, no pops, bangs or smoke, just silence.
Can anyone give me some idea where to begin?
Thanks
Rob
