Hi.

I have 15" CRT monitor VISION DX-1564 (~1998), operating at 1024x768.
It supports refresh rate of up to 75Hz at 1024x768 and 60Hz at 1280x1024.

I wish to use 75Hz refresh, but when I put 75Hz refresh rate, the image
has very bright lines. When I put 70Hz the image is good.

What can be causing this problem?
The monitor is connect to S3 video card.

Get an engineer to slightly turn down the flyback screen control to
see if will adjust it,it should.

That's not a fix, he said it's brighter at a higher refresh rate, which is
unusual, normally it becomes darker. Did the problem happen gradually? Does
it change at all as the monitor warms up? If so I suspect a capacitor is
failing, if it happened suddenly then I'd look for a cracked solder joint
around the HV section or a shorted transistor in the regulator.
