Marantz 5010b problem - no sound

Hello,

I recently got a hold of a Marantz 5010b cassette deck. I replaced the belts and cleaned the contacts.

But, when playing a cassette, I get no sound. That is, no musical sound, just a weird humming, motoring sound that follows the rhythm of one of the VU-meters that is going berserk. I uploaded a video to better describe what I mean:

Does anyone know what could be causing this, and how to solve it?

Did you clean the rec/play switch? this is a long metal cased switch, usually mounted on the main board that has some sort of physical connection to the mechanism, usually the record lever, either by string, spring or some lever system. These usually show this symptom when dirty. Best method is to jet some contact cleaner into it and work it back and forth. If you don't have contact cleaner you could get it going for now just by cycling this switch and it may work for a little while.
 
I've noticed the 5010b has a ground chassis binding post on the back. Do I need to connect it to the amp (a Marantz 1060)? And how do I go about doing this?

I'm learning everyday!
 
Usually a grounding post is supplied on an amp and a turntable. Just one piece of hook-up wire needs to be connected between each of these to get rid of any grounding hum. Have probably seen them on a tape deck but never gave them a second thought and never used one.
 
Yeah, my turntable is already grounded with the amp, so I didn't really see the point in hooking the cassette deck up as well. Just thought I'd ask. Thanx!

More than 10 years later, and this post just made my day. I got a 5025 with similar issues, I thought the deck is fried for sure. Such an easy fix, and works like a charm. Thanks!!
