Default Capacitor Testing.

I currently have a LCD projector in which I believe the convergence
circutry is messing up. Since this unit has quite a few electrolytic caps
in it, I think theres a good possiblilty that there could be a few that are
bad. Unfortunately my ESR metere is 2,000 miles away. Ive considered
buying another meter since it would be nice to have, but is there any good
way to check these things without a meter? I have a DMM and a soldering
iorn here. thats about it. They are all small SMD caps which fortunately I
think I can get locally here.. I could probably replace all of the caps
cheapr than buying another meter, but that is a pain.


DMM set to AC volts. Measure both sides of the capacitor with the projector
on. In a good capacitor, the voltage will be the same or close.

Yes, I know, that is crude but sometimes effective.
