scope, that will make your troubleshooting a LOT easier. If you don't have
a service manual, you really should get one. You can buy a digital copy
from http://artekmed.startlogic.com/page2.html for $10.00. Artek sells high
quality scanned copies; I can recommend them from personal experience.

I never buy from this kind of shop since their business model seems
dodgy to me. Basically they sell copyrighted works of others, and stuff
that is sometimes freely available elsewhere.
