AFFECTS
All metal cabinet monitors.
DESCRIPTION
Modifications to bring cabinet back wire routing, dressing and securing in
line with current production practice.
IMPLEMENTATION
These modifications only apply whenever a monitor is returned for service.
MODIFICATIONS
With the cabinet top removed check the following:
Signal Wires On Cabinet Back Components
(DIN sockets. BNC sockets, mode switches, brightness/contrast controls etc).
- It is now the practice to fit a 'tyrap' fastener onto the signal wires on
each component. (See diagrams). A
'tyrap' should be fitted to any component which is found not to have one.
Note: The signal wires are already mechanically twisted onto each pin and
then soldered : this modification provides additional wire attachment.
- If it is possible to move any of these signal wires away from its normal
position to touch the small exposed section of the terminals on the main
switch then sufficient 'tyraps' should be fitted to these wires to hold them
in position.
Note: This does not apply to wires which are already contained within a
secondary sleeve.
Single Insulated Mains Wires On Mains Switch
This only applies to the short sections of mains cable from which the outer
sheath has been removed to allow the individual wires to be attached and
soldered to the mains switch.
If it is possible to move any of these short sections of wire away from its
normal position to touch a pin on one of the cabinet back components then
sufficient 'tyraps' should be fitted to the mains wires to hold them in
position. (See diagram).
NOTES
This HTML version of the Microvitec Service Manual for Series 3 Colour
Display Monitors differs from the original printed manual mainly in the
order of presentation of the various sections and in the arangement of the
Parts Listing according to component type. The circuit diagrams and PCB
layouts are included in their own, separate directory - 'diagrams'.
No responsibility can be accepted for the accuracy of the information
contained herein, especially since the original, printed manual is not
available for reference.
WARNING
Cathode ray tubes operate at extremely high voltages which may persist
for some time after the monitor has been switched off and disconnected
from the mains supply. Always refer servicing to qualified servicing
personnel.
Always follow the precautions indicated in the "
Handling Precautions and Operating Safety" section.
