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.

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.

DANGER

! Use caution when making adjustments with the cover removed.
! There are high voltages on the analog and video cards

Symptom	Action
Displayed image width too large or too small	Adjust RV354, RV355 (8517 only), RV356, and RV357 - If symptom persists, replace analog card
Displayed image height too large or too small	Adjust RV211, RV212, RV213, RV214 (8517 only), RV215, and RV216 - If symptom persists, replace analog card
Contrast or brightness controls not working	Check connections between H3 (Fig 8-7) and B6 (Fig 8-11) If good, do pod assembly checks - Replace pod if it is defective - Otherwise replace video card
Maximum or minimum white is poor	Video colorpoint is not set - Adjust as appropriate
Pattern is out of focus, vertical lines have colored edges or are multicolored	Do Focus and Convergence adjustments
Geometry is poor	Follow Geometry Alignment procedures - If impossible, replace analog card
One or more colors missing	If colors good with test raster (signal cable disconnected), check connector B1 (Fig 8-11) - Check connector on system unit - If symptom persists replace signal cable - If symptom still persists replace video card
Displayed image does not synchronize horizontally or vertically	Check connector on system unit. Ensure that D6, B2, and B11 are connected (Fig 8-11) - If symptom persists replace analog card - If symptom still persists replace video card
Background raster is not centered horizontally	Adjust RV506 (Fig 8-8 or Fig 8-9) - If raster cannot be centered, replace analog card
Displayed image is not centered horizontally	8517, adjust RV403, RV404 and RV405 (Fig 8-8) 9517, adjust RV403, RV404 (Fig 8-9) - If image cannot be centered, replace analog card
Displayed image is not centered vertically	Adjust RV204 (Fig 8-8 or Fig 8-9) - If image cannot be centered, replace analog card
Displayed image height varies excessively between modes	Adjust RV211, RV212, RV213, RV214 (8517 only) and RV216 - If image cannot be centered, replace analog card
