tims@starfish.Convergent.COM (Tim Simmons) (10/03/89)

 I think Iremember reading something about this problem a while
 back.  If so please send me any info on this problem:

 I have a MAC+ that is about 4 years old, for the past several
 months the video display has been exhibiting a strnge problem.
 The screen image jitters from side to side, for short periods of
 time (2-3 second duration), this happens every time I use the
 system. at least a few times per hour.

 Does anyone konw what the source of this problem is and what it
 takes to fix it?

 Thanks in advance

It could be cracked solder joints or a bad C1 capacitor.  Check with a
component level repair shop (like MacDoctor Electronics in Mt. View)
for repair.  It saves replacing a board.
