Sounds like it could be a power supply regulation problem. Would not A/C hum in one or more supply cause that? If so likely culprit is the large filter capacitors in the power supply.
Another possibility -- when turning on most color monitors, there is a 'degaussing coil that is activated, and it shuts down when a series thermister heats up or a relay cuts out. If that were damaged or leaky the degaussing coil might continue to activate, but I don't know if that is a likely problem. (The initial waviness on many monitors, accompanied by a noticeable hum that fades out, is the degaussing coil. There is usually a button on monitors that will activate it, so you can test for that by pushing the button if it exists to see the pattern it creates.) I'm going on GENERAL monitor problems and old and slight background in TV repair, I don't know Mac monitors specifically so take this as suggestion only. -- Gordon ----- Original Message ----- From: "Durkin, Sean" <[EMAIL PROTECTED]> To: "Quadlist" <[EMAIL PROTECTED]> Sent: Wednesday, June 25, 2003 9:14 AM Subject: LC 575 Display Waviness Hi- I fired up the old LC 575 and am having terrible screen waviness. I moved all magnet type things (other computers, speakers, monitors) away from it and the problem persists. The screen starts very wavy and then settles down to a milder wave or shimmer. It's not located near any other electrical fixtures or wiring. The cord is attached to a surge protector. Are there any adjustments to be made to correct this? Can I degauss? How? Please, point me in the right direction!!! I've done a number of searches, but wasn't able to find anything specific. This is the final piece of the mighty Mac network at home.
