[comp.sys.mac.hardware] flickering screen

mil@mendel.acc.Virginia.EDU (Maria I. Lasaga) (11/19/90)

Hello.  Sorry if this question has been asked before:  My SE is only
a year old, and the screen has been flickering and dancing a bit lately
(which is really annoying)...is this possibly a problem with my surge
protector or house electrical wiring, or is this a problem with the
machine itself?  If it sounds like the machine, does anyone have a rough
guess for what a repair like this would cost?

thanks.

A friend has noticed the same problem with a new Mac Ci,
and traced it to her laserwriter being plugged into the same
mains circuit. Also caused a lamp to flicker every 20-30sec.
Anyone else noticed this? Is it dangerous for the hard drive?
