Missing or incorrect colors due to lengthy video cable.
Cause:
Video cables longer than 6 feet or 2 meters can distort the image and cause characters and colors to drop out of an image that seems otherwise fine.
Solution:
Replace detachable lengthy video cable.
1) Turn off the computer and all components.
2) Unplug the display unit power cable from the surge protector or wall socket.
3) Disconnect/reconnect video cable to computer:
a) Use a small flat-tip screwdriver to loosen screws holding video data cable onto connector on back of the computer.
TIP: Trace the video data cable from back of the display unit to back of the computer.
b) Note the orientation of the plug to the socket. Grasp video cable plug and pull it straight out of the socket.
CAUTION: Forcing it could damage connector pins or socket; ensure screws are completely loosened.
c) Connect the data cable to the video card socket on back of the computer.
1] Locate the same 15-pin socket where the old video cable was removed.
2] Orient the plug so that it matches the socket.
3] Insert the plug into the video card socket until it is firmly seated.
NOTE: DO NOT force it. If the plug does not fit, check plug orientation (it fits only one way) and ensure the correct socket is being used.
4] Tighten the securing screws.
