Still working on this unit. I soldered the components on the cylinder motor,
checked for debris, soldered
power supply area including Q805 and IC604 and placed a thin film of Q-Dope on
each side of the ribbon
cable to make a tighter fit, still, the heads will not rotate once in a while.
Could the motor driver IC(IC604?) be intermittent?
It seems to act up the first time I insert the cassette only...2nd time OK. If
I let it sit 10 minutes or
so, it does the same thing....acts up first time, second time rotates.
Thank you.

Subject: [TechAssist] RCA VR639HF..Intermittent no cylinder rotatiion
This unit came in with no cylinder rotation. After a rew attempts and flexing
the ribbon connector on the
motor it worked. While trying to localize the bad connection I can not get it
to act up again and the
cylinder rotates every time.
I have flexed the ribbon cable at both ends as well as both connectors and the
motor section, but I can
not get it to stop working. Has anyone any case histories on this...solder the
motor PCB, connectors or
replacing the ribbon cable? Also ruled out bad connections on Q805.
Thanks.
