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.

spares then please tell PALsite
