NOTE: This web page is INCOMPLETE, as it is restricted to 8517 / 9517 Specific Information. There are further safety procedures specific to the 9517 that are earlier in the Displays HMM.

I am not responsible for any outcomes of attempts to use any information on this page.

Review the High Voltage Discharge Procedure in section 1.3.4 of the PS/2 Display Hardware Maintenance Manual, Vol 1 [SA38-053-00 or -01].

If you are unfamiliar with safe adjustment of equipment that has voltages of 23KV, this is NOT the place to start! This includes using the proper insulated or non-conductive tools specified by IBM.

IBMDSPLY.7z IBM PS/2 Color Displays Test Pattern Diskette (41G8502) [720k]

The IBM Personal System/2 Color Displays Test-Pattern Diskette examines the mode configuration from the monitor and the type of computer being used and displays the modes available for the monitor.

So, you have a non-IBM monitor hooked up, chances are it does not use display ID Bits like the program expects. So it might be self-limiting to the supported modes. The test program does modes 1-4, -AND- Mode 4 can be modified to give -MORE- modes..

Setup Patterns
Pattern A - Crosshatch
Pattern B - 50 mm Square Box
Pattern C - Full Screen Raster
Pattern D - Grey Scale
Pattern E - Focus Pattern

IBM PS/2 Advance Function Display - Setup Modes V1.01
Mode 1 - 720 x 350
Mode 2 - 720 x 400
Mode 3 - 640 x 480
Mode 4 - 1024 x 768
Mode 5 - 1360 x 1024

NOTE: This is a common-sense progression of diagnosing your 9517. The 8517 might use a different rear cover., but is similar in construction. We start with a Self-Test, because the issue may be cabling, software drivers, or a problem inside the system unit. Then we remove the rear cover, remove the EMI shield, discharge the CRT, then on to the Function Tests.

NOTE: When you test Patterns, the reason why the Color Displays Test Pattern Diskette is bootable is because the problem(s) may be due to software mis-configuration. Running the Test Pattern Diskette from the command line instead of booting with the Test diskette may allow software mis-configuration to still continue.

NOTE: At present, I am slightly confused on IBM talking about HV Discharge before removing the EMI shield. From looking at the illustrations, the EMI shield covers ALL electronic components, which includes the anode suction cup...

1.3.3.2 Rear Cover, Type 2 [Remove / Replace]

The removal procedures for this type of rear cover are:

1. Turn power off at system and display, disconnect all cables ("Powering Off System" 1.1.3).
2. Remove tilt swivel stand ("Tilt Swivel Stand" 1.3.1), or lift tilt swivel stand ("Lift Tilt Swivel Stand" 1.3.2).
3. Refer to Figure 3-4.
4. Remove covers 1 from the two securing screws 2 on the top of the rear cover 3.
5. Remove the four screws 2 from the rear cover.
6. Ease rear cover away from the display.

Figure 3-4. Removing Rear Cover, Type 2

2.5.1.3 Pod Assembly [Remove / Replace]

The pod contains control and filter cards.

1. Refer to Figure 8-1
2. Remove three screws 1 securing the pod.
3. Disconnect earth lead 2 from card tray.
4. Release two latches 3 with a flat-blade screwdriver and ease pod back.
5. Remove power connector 4 from filter card to analog card.
6. Remove connector 5 from control card to analog card.

Figure 8-1. Removing the Pod Assembly, 8517 Display

Replacement: Replace the Pod Assembly using the above instructions in reverse order.

NOTE: I would expect the 9517 to be similar.

2.5.1.4 Electromagnetic Interference Shield[Remove / Install]

1. Refer to Figure 8-2.

2. Remove three screws 1 from each side of the shield, and the ground wire 2.

3. Lift shield at back, move it away from retaining slots on ITC shield.

Figure 8-2. Removing Electromagnetic Interference Shield, 8517 Display

Replacement: Ensure that spring tabs on bottom of interference shield are correctly disposed on either side of the card tray, and the ground wire is reconnected.

NOTE: I would expect a 9517 uses a similar EMI shield.

2.5.2.4 Adjustment Procedures

CAUTION

! Use extreme caution when making adjustments with power turned on at the display; these adjustments should not be performed unattended.

! The display must never be left unattended with the covers removed and power turned on in a customer environment.

Refer to the "Display-Specific Removals and Replacements" in topic 2.5.1
for details of how to get access to maintenance controls.

All adjustments must be completed in the sequence given here.
