After multiple tests, I finally figured out why my monitor was showing only blue and yellow (no red): The monitor cable --after all these years-- has finally broken (or to be exact one of the wires inside the cable appears to be loose) about two inches before it connects to the video card. If I move the wire 'just so' and apply pressure to it, the monitor shows its full array of colors.
The cable unfortunately is attached to the monitor. (At first I thought I could simply unplug the cable and replace it.)
Question: Is there any way of repairing this cable? Is it easily replaceable? (This is a Dell Monitor that came with my old Pentium 90.) Is it safe to open up the monitor --I am aware of the shock potential-- and simply replace the cable.
Does it have to be a specific cable or can any generic cable do the job?
Thanks. I have never messed around with monitors.
