1735 HD High Definition Waveform Monitor
There are four cushions in the front panel opening which should be in place
when the CRT is reinstalled.
5. Disconnect the anode by separating the connector from the multiplier on the
Power Supply board (A1). Do not touch the exposed tip of the connector.
Discharge the connector tip to the chassis. Disconnect J5 from the Control
board if necessary to reach the anode connector.
1. Slide the CRT partially into position and reconnect J4 to the Control board,
with the red lead to the top of the instrument.
2. Position the base of the CRT near the plastic CRT mount.
3. A socket and clear plastic cover are contained in the plastic CRT mount.
Remove the clear plastic cover (but do not remove the socket) from the CRT
mount. The two nuts that attach the mount to the instrument chassis can be
removed, so that the mount can be moved if desired.
CAUTION.
Avoid bending the CRT base pins when pushing the CRT into the
socket. Do not pinch wires between the CRT and socket.
4. Slide the CRT back toward the CRT socket. Holding the socket from behind,
align the socket to match the CRT base pins and push the CRT into the
socket, matching up the notches in the CRT with those in the mount.
5. Reinstall the clear plastic cover on the back of the CRT socket.
6. Be sure that the four cushions are in place in the corners of the front panel
opening.
7. If the CRT mount nuts were removed in step 4, push the CRT into place and
position the CRT mount on the chassis posts. Replace and tighten the CRT
mount nuts.
8. Connect all four deflection leads (red, green, blue, and brown) to the CRT.
See Figure 7–5.
9. Clean the face of the CRT to remove fingerprints.
10. Reconnect the anode connector to the HV Multiplier on the Power Supply
board.
11. Install the bezel.
