TP 750 - External Display Problem when Attached to the 750 Mono.

Applicable to: World-Wide

Symptom:
A line of data or a portion of a line of data will vibrate or waver. The condition may jump from one area of the screen to another.

Problem Isolation Aids:
This only occurs on the external CRT. The mono LCD works correctly and does not exhibit the symptom.The symptom has only been seen using OEM DRAM memory.

Fix:
Remove the OEM DRAM memory and reboot. If the CRT does not waver install an IBM DRAM of like size for DIAGNOSTIC PURPOSES ONLY. If this fixes the problem, remove the IBM memory, and go to your point of sale for OEM DRAM card resolution. If the problem remains follow normal problem determination procedures.
