No red or green on monitor after move

[Terry Marshall]

I would be very grateful if anybody can help me with this
problem. I moved my PC to another room. After it was
reassembled all worked as it should except the monitor
colours. I can only get blue and yellow but red is more of
a dark brown and green is is a dirty yellow. This has only
happened since the move and it worked perfectly before. I
thank in advance anybody who can help me. Yours sincerely
Terry Marshall.

A couple of things come to mind. Degauss the monitor,
this should be in the setup or users menu for the
monitor. The second things to look at is the video
connector itself, make sure NONE of the pins are bent, if
so, carefully straighten them out with a pair of needle
nose pliers.
