    Look for cold solder joints and/or bad electrolytic capacitors. These
    monitors are usually TTL monochrome units and fairly simple.

    Easier said than done. This could easily be a system from the mid 1970s, the
    monitor will be non-standard and custom fit into a control system on a
    machine tool. This sort of thing is worth repairing.
