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.

Thank you for the advice everyone!
I have not done anything to the deck yet. I thought I would let it sit overnight and see what happens.

So far the deck plays but it does so wobbly. The rewind does not work but it sounds like it wants to engage. The fast forward does work for a bit and then quits.

As the deck is playing, I noticed that dolby b & c work. The monitor button works. But the switches for 70μS/120μS and normal/chrome/metal are not working. So that might be where the problem lies. I'll blow it with some compressed air when I get home from work.

Tonykay- I hear you and agree. I just don't have the cash to have this thing serviced. I am fairly competent so I try to do most of the maintenance on my own. I admit like many others I might know enough to be dangerous but not enough to call myself a tech!
