1.3.1 Tilt Swivel Stand

The tilt swivel stand is the same for most models, but some have a

different method of attachment and some lift as well as tilt and swivel.

1. Power off the system and the display, and disconnect all cables. (See

"Powering Off the System" in topic 1.1.3.)

2. Place the display on its front cover, protected with a soft cloth or

similar material.

3. Remove the thumbscrew 1 , disengage the locating hooks 2 , and move

the tilt swivel stand away from the display.

Figure 3-1. Removing the Tilt Swivel Stand

Other displays have a tilt swivel stand that is held on with two release

clips. For those types of stands, use these instructions after powering

off the system and removing all cables.

1. Place the display on a flat surface, ensuring that there is sufficient

space to set the display down after removing from the stand.

2. Press the two release clips at the front of the stand assembly.

3. Pull the display forward from the tilt swivel stand.

4. Lift the display from the stand and place it on a flat surface.

Replacement:

Replace the tilt swivel stand by using these instructions in reverse

order.

Rear Cover, Type 1

The removal procedures for this type of rear cover are:

1. Power off the system and the display, and disconnect all cables (see

"Powering Off the System" in topic 1.1.3).

2. Remove the tilt swivel stand (see "Tilt Swivel Stand" in topic 1.3.1),

or the lift tilt swivel stand (see "Lift Tilt Swivel Stand" in

topic 1.3.2).

3. Refer to Figure 3-3.

4. Remove the two securing screws 1 from the rear cover.

Some models have only a single hex head screw on the bottom of the display

that must be removed. Additionally, these covers may require that you

unclip two plastic closing plates from the interface cable to allow the

plug to pass through the cover.

5. Insert the delatching tools 2 into the slots to release the

fasteners.

6. Ease the rear cover 3 away from the display, after disengaging the

signal cable from the retention slot.

Replacement:

Ensure that the securing arms of the card tray assembly are latched into

the front cover.

1.3.4 High Voltage Discharge Procedure

This section describes how to discharge high voltages from the exposed

components of the display.

DANGER

________________________________________________________________________

| |

| Hazardous voltages are present on the analog and video cards. |

| |

| The extra high tension (EHT) voltage on the CRT anode cap exceeds |

| 23 kV. Use extreme caution when working on the display with the |

| power on and the covers removed. |

| |

| Some adjustments require you to place tools close to the EHT |

| voltage. For safety and performance reasons, only plastic or |

| insulated metal tools should be used. |

| |

| Remove all jewelry before starting any repair process. |

| |

| Never leave the display unattended with the covers removed. This |

| applies whether or not the power cord is connected to the power |

| outlet. |

| |

| With the power cord connected, voltage may be present at the power |

| supply card even with power switched off. |

| |

| A static charge may be present at the line cord connector, at the |

| rear of the display, if the line cord is disconnected before the |

| power is switched off. |

| Always turn the power on/off switch off first, then wait |

| approximately five seconds before unplugging the power cord from |

| the back of the display. |

| |

| Under fault conditions, a static charge can remain on the CRT |

| anode long after the power cord has been disconnected. For this |

| reason, it is important to discharge the CRT anode before |

| disconnecting the anode lead. |

| |

|________________________________________________________________________|

To avoid any shock hazard when working in the area of the high voltage

anode lead, use the following to discharge the CRT to ground:

7838688 or equivalent) attached to each end; or Meter Lead Kit (part

6428104).

Please read the complete discharge procedure before starting; then

continue in the order given.

1. Power off the system and the display, and disconnect all cables (see

1.1.3).

2. Remove the tilt swivel stand (see "Tilt Swivel Stand" in topic 1.3.1),

or the lift tilt swivel stand (see "Lift Tilt Swivel Stand" in

topic 1.3.2).

3. Remove the rear cover (see 1.3.3).

4. Refer to Figure 3-5.

5. Connect one end of the jumper 1 to the CRT ground 2 , and the other

end to the screwdriver shaft 3 , except for models 8517 and 9517.

Figure 3-5. Connecting the Jumper for CRT Discharge

For display models 8517 and 9517, connect the jumper between the shield

around the integrated tube component and the uninsulated part of the

screwdriver shaft as shown in Figure 3-6. This will discharge the anode

of the CRT 1 to the ITC shield (ground).

For display models 8517 and 9517, connect the jumper between the shield

around the integrated tube component and the uninsulated part of the

screwdriver shaft as shown in Figure 3-6. This will discharge the anode

of the CRT 1 to the ITC shield (ground).

6. Do not touch any conductive parts when discharging high voltages.

Insert the blade of the screwdriver under the suction cup until the

end touches the anode lead connector 4 .

7. Do this several times to ensure a complete discharge.

8. Carefully remove the anode suction cup from the CRT.

Note: Remove the anode suction cup immediately after discharge, to

prevent the CRT capacitance from recharging. If you are delayed

for more than a minute or two, perform the discharge procedure

again.
