Barcrest Lucky Strike MPU4 startup problem!!

[iaino]

Hi there folks,

I hope someone can help me!

I have a Barcrest Lucky Strike MPU4 machine.

When I plug it in, all that happens is lights 2 and 5 on the 'take nudges' column flash once. That's it.

I tried replacing the MPU4 unit with the same result!

Does anyone know how to fix this problem?

Thank you in advance,
Iaino

Assuming you replaced the MPU4 with a known good unit, there's not much left to try. I would be looking at the PSU next, but make sure you get the correct one.
