TSG 95 Service Manual
If a part that has been ordered is replaced with a new or improved part, the local
Tektronix field office or representative will contact you concerning any change in
the part number. After repair, the circuits may need readjustment.
Only #4 screws are used in the TSG 95 to secure the case halves together. DO
NOT USE MORE THAN 3 INCH POUNDS (0.34 N
m) OF TORQUE ON
THESE SCREWS.
Replacing Assemblies
WARNING.
Disconnect the AC adapter and batteries before replacing any
components.
Follow this procedure to remove and replace the back cover of the TSG 95:
1. Remove the four screws securing the back cover to the front cover.
2. Gently separate the back cover about 1 inch from the TSG 95, taking care to
not pull the rear panel (connector panel) away with it.
3. Disconnect the battery cable from J10. Make sure to pull on the connector
housing to do this, not the wires. The back cover is now free and may moved
away from the instrument.
4. Replacement is the reverse of removal.
Follow this procedure to remove and replace the connector (“rear”) panel of the
instrument:
1. With the back cover removed, disconnect the VIDEO and both AUDIO con-
nector cables from J7, J8, and J9. Again, pull on the connector housing, not
on the wires.
2. Slide the connector assembly up away from the front panel.
3. Replacement is the reverse of removal.
Follow this procedure to remove and replace the TSG 95 Main board and LCD:
1. After removing the rear panel, use a pair of needle-nose pliers to gently pull
the J2 housing up away from the instrument. Pull straight up, lifting the
Main board at the same time. Do NOT bend the connector housing.
