Vectrex repair - please help!

[sideburn]

Can someone please answer me all or even just one of these questions:

 

Should the picture tube be lighting up even if logic board is disconnected?

 

What voltages should I see on back off crt and near the high voltage transformer?

 

If this is not the place for tech help, is there another vectrex forum where I can get some troubleshooting support?

 

Thanks! I am desperate for some help trying to repair my vectrex. The picture tube is dead but I'm seeing voltages that look correct so I'm wondering if the crt itself is bad. I got no replies from my first post so I guess this one will be my last try

Have you looked at the service manual? It should cover all necessary voltages.

I highly doubt your crt is bad. Your high voltage is likely the problem. Things to check - Power supply volatges, 555 timer, High voltage transistor.
