******     HELP !!!!!!     ***************


I hope that somebody out there can help me
It seems that my 1000EX has a problem with a video ram chip.
When I run programs like Lotus (lately) my screen flickers with any cursor
movement.  I called the local TRS technician and he diagnosed the problem
as to what I have just described.  My problem is how do I locate the bad chip
and if it is a bad chip then why when I boot up the machine it says 640 ram OK.
This problem does not happen with graphics programs like surfer or flight
simulator so I really don't understand why this is happening.

THANKS FOR ANY HELP
