Scanner help
In going through some of my spare scanners, I have a set that does a decent test pattern at 30K, looks good with graphics and most abstracts, but with heavy abstracts with many circles tight or triangles very close and spinning the signal seems to get noisy and ripple. Looks like hash on a supply voltage when caps fail.
Ideas, I seemed to remember reading something about grounds and there level changing during heavy swings of scanners. What might I look for or do scanners just fail like this as they die.
Thanks
