Troubleshooting First Checklist/ - 2
First Checklist
Important:
Many Apple Multiple Scan 15AV display modules
returned for repair are found to be fully operational. Read this
checklist before you return a module, and prevent needless module
replacement and unnecessary time delays.
The Apple Multiple Scan 15AV Display is not
compatible with all computers.
This display works with both Macintosh and IBM PC-compatible
computers. A video card may need to be installed to use this display
with some computers. For more information, see the computer
manual.
For more information on what computers or video cards are
compatible with the display, see the Specifications chapter.
The CRT raster will not always resemble a perfect
rectangle.
CRT tolerances allow for some distortion. Additional distortion can
be caused by magnetized metal objects (such as desks or file
cabinets). Move the unit to a different location if you notice raster
bowing or bent raster edges.
Jitter, faint lines, or screen movement can be caused
by external interference such as electronic devices
and fluorescent lights
.
Fluorescent lights, other monitors, or electronic appliances
(such as coffee makers and copy machines) can cause raster
distortion. Move the unit to another room or building to help
determine if external interference is the source of the problem.
Note:
If the raster has shifted up/down or right/left only, adjust
it using the user controls. However, keep in mind that, if you then
move the monitor, you may need to readjust the centering
controls.
If the display changes (for better or worse) when you move it to
another location, the environment is the source of the problem.
Relocate the monitor or move the distortion-causing object.
