Well, if the Hsync pulses are indential whether the
display
is stable or not, then the Hsync generation circuitry is not
the prolem. And if the monitor is not locking to them, the
fault is either the monitor or the PSU, presumably.
As the monitor will lock to them when the computer has crashed, I wonder if
it's noise from somewhere interfering with the video signal generation? Or,
perhaps, the monitor itself is being subjected to noise which is trashing
the display.
Whatever the cause, it's definitely only when the machine is running that
the problem manifests itself.
Cheers,
Ade.
