Go Video GV-4020 - Intermittent Problems

[ntlworld]

I need help to remedy an intermittent problem with deck#1 of a GV-4020 go
video deck. The functions are dead most of the time. If you unplug it and
plug it in, it will sometimes function untill you unplug it again.

The service manual is no longer available thru regular service centers and I
tried everything from swapping parts from #2deck and resoldering entire
board. I suspect the Syscon (I.C.) but have no info or experience with this
unit. I have been told that the problem is typical of these Dual tape units.

Thank you for any help,

I've had problems with "cold solder joints" on the front circuit board. Take

the front cover off & remove the front circuit board. Check the connector
where the board connects to the main circuit board.
