On the plus side these VCR's were construted 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.
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 PCB's 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.
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
