CRT Monitor loses Green
in [Repair]

From: William Sommerwerck on 14 May 2010 11:13 Start by checking the cable for an intermittent contact or wire. It could be something as simple as that. If you have access to another monitor+cable, use them to confirm that the problem really is with the monitor, and not somewhere else.

Start tapping (bashing) the thing with a hammer (well, I used the plastic handle of a large screwdriver :) See if you can locate where the intermittent connection is. A while back I had a monitor that dropped a colour like yours and even after opening the thing up and remounting every connector I could see, right through to the CRT socket, I never found the fault. By the time I retired the monitor the case plastic was quite marked in places from the fairly hard bashing I gave it to get the colours back. Grant. -- http://bugs.id.au/

Is it on a KVM? I had one go bad that-a-way. Jonesy |
