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.
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.
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.
