Power Issue with a Zenith SM1973 System 3 Space Command with Space Phone

[mpatoray]

Hi,

This set was our basement TV after i snagged it at the ETF a few years ago for $5. It was made in 1979, has the Ultrasonic Space Command 3500 remote, and all of the documentation, including the bill of sale dated 10/30/80 for $689.95 without the stand, manual and door hang tag.

I want to turn it on one day, and all it does is make this mototboating type sound out of the speaker, no picture or anything else.

Any ideas about this issue, or which module in the mess of modules and wires that could be the issue.

I have never worked on a Zenith before.

Thanks,

Matt
