My A2002 turned itself off once after snapping.  After about the 20th "snap!",
I went in and applied the 1084 fix to it.  No more popping.

It also turned itself off the first time I tried to connect the video output
from my VCR to composite-video input on the A2002.  Then I discovered the
nasty ground loop between the cable company and the 120 volt wall outlet.
There was approximately 5V AC difference between the two "grounds".
Looks like it triggered the crowbar circuit in the power supply.
