If the picture is off centre, there is obviously a component(s) that has

try tweaking it to compensate for an error. I am sure that the monitor
originally did not have the fault you are describing. In a monitor that
old, it is more than likely that there are a number of high ESR capacitors,
and maybe even some resistor values that have drifted out with age, and
whatever use the monitor had.



That's not always true, these things quite often got fiddled with, or
just mechanical vibration would muck up the adjustments, or the monitor
may have come from some other game and been swapped in without adjusting it.
