1989 ADC , getting no picture

[Airedale]

Well I picked this up today, cleaned it up, hooked it up to my cable and plugged it in. I get static, but no picture at all, just static.

I tried playing with the tuner, every channel. Moved the (vhf to cable) adapter from vhf to the uhf, no difference.

There is zero change in the tv when it's hooked up to cable, as when it's hooked up to nothing.

Any ideas what may be wrong with this?
