So i am here tearing into this Macintosh Classic.

Pulled out the A/B board, Had to re-cap it, Screen was wavy, HD would not spin etc. etc.

Anyways, Replaced all the caps following my recent post. viewtopic.php?f=7&t=21471

And, Everything now works great!! HD fires right up!

Screen is Solid and Bright.

Only now there is this line. Basically after a few hours of Probing... testing...

I had a hunch that the issue might be caused by external interference.

Whenever I test Compact macs, I always test them with the rear can off.

So I put it all back together, tightened the screws up.

Then fired it back up.

And sure enough this " traveling line " syndrome I was experiencing had went away.

(The line was slight and it would travel from top to bottom of the screen all the way across).

Kind of irritating, because I wasted about 2 hours trying to track this issue down.

At-least it works now.
