General Construction On the plus side these VCR's were constructed
in a modular fashion with each printed circuit board carrying out a
distinct function. On the down side, these many PCB are connected
together using plugs, sockets and wire links which are prone to failure.
The electronics inside the VCR's is by todays standard fairly straight
forward with many discrete componenets being used together to perform the
complex functions required. This means getting hold of components to repair
electrical problems is by and large still possible. However this good
news is more than wiped out by the fact that it is now near impossible
to get hold of mechanical parts such as pressure rollers, capstan motors
and video heads. For the most part it is a case of having to break up
several machines to get one working.
Dry Joints Like most V2000 models this VCR suffered from problems
associated with dry solder joints. Before carrying out anything else it
is advisable to check the PCBs for dry joints. In particular the power
supply section and it's linear regulators should be checked.
Also prone to failire were the drive circuits for the video
head actuators. These supplied high voltages to activate the
piezo-electric actuators and as such were under stress most of the time.
A good maintainance procedure is to replace all the capacitors in this
part of the VCR and to resolder all joints.
Video Heads If the VCR suffers from mistracking
first check the voltage drive to the piezo-electric crystals used in
the Dynamic Tracking circuits. Video heads for V2000 machines are now
rare and extremely difficult to obtain.
