If it were standard electrical parts (such as caps and transistors in a
power supply of a dead monitor, they can be replaced). But if you're
getting erroneous behaviour that's more likely to be specialised parts
of the monitors. Such parts may be available, often only as whole
board swaps, for new and current model monitors, but not for
discontinued monitors. Pricing may be extortionate.
Often there are some generic boards available that suit a wide variety
of models, but you have to find the right ones, find someone selling
actually working ones, fit them. Again, pricing may be ridiculous.
NB: If you're coupling unearthed equipment (be that your monitor or
PC, where one or both are unearthed), you really want them all to be
fully powered off while connecting or disconnecting them. Unearthed
equipment can float at high voltages (generally not a problem for
humans) but can zap ICs directly connected to the ports. This can zap
things instantly, or can cause eventual breakdowns (equipment may fail
long after connecting them up, so you never attribute the fault to this
action). Of course, equipment does spontaneously die for no apparent
cause, but the above scenario is more common than you'd think.
"unearthed"? I know that isn't meant literally, but I don't know what
you do mean. What is "unearthed" in this context?
