Used contact cleaner on Nak BX-300; now broke

Hello,

I had some crackling with the bias knob on my Nak BX-300 cassette deck. So I pulled off the knob and sprayed some "TV-Tuner/Control Cleaner & Lubricant" aka contact cleaner on it.

While I was there I sprayed some cleaner into the volume and recording levels and some in the pitch control.

Turned the deck on and now it's gone haywire. It acts like a deck that needs new belts; the unit refuses to rewind or fast forward. It also refuses to play. All lights work and the motors seem to be working. The belts were replaced a few months ago so that should not be an issue.

What do you guys think? Did I short this unit out or break it? How can I fix it?

PS The deck worked just fine before I sprayed cleaner in the knobs.

If you are saying that you did the spraying from in front of the front panel, with the knobs removed, I doubt that it would have accomplished anything anyway, in terms of improving control operation. You have to get the spray inside of the control, which usually means spraying it into an opening on the control that can only be accessed from inside. Some controls are fully sealed, in which case effective spraying is not possible, although sometimes just rapidly rotating the control back and forth a number of times can help somewhat.
