1. Disconnect the old cap and leave it physically attached to the chassis. Leaving the old cap in circuit is just asking for trouble sooner or later. I still run into a few modern TV's where the "technician" just bridged an electrolytic cap across the underside of the PC board, leaving the old cap in place.

2. Always replace all sections of multi-section caps even if the other sections are good. I found this out the hard way on a 19" GE solid state B&W and a 19" solid state Sylvania color TV. Both times, the set worked for about a week and then another section of the can went bye-bye. Even though it means more work, I now always change the entire cap.

3. I'll agree that those old style cap testers from 50 years ago are the best way to actually test a cap at rated working voltage. Well, the BEST test for a cap is a new cap.

4. I'm now to the point where I change all paper caps and the cardboard tube electrolytics. I'll sometimes let the can caps slide, depending on how new the equipment is and if the old cap runs warm or not.
