[comp.sys.atari.st] Trembling monitor

U00170@HASARA5.BITNET (10/10/87)

I am having some troubles with my SM124 monitor.
It sometimes starts trembling, causing the screen to become
narrower and higher .
Who knows what might cause this problem. It is not due to an other apparatus
wich interferes with the monitor.

Greetings,
