You'll find many posts on DUC and elsewhere talking about skin contact issues (try licking your finger) and electrical connection between the cap and post (try testing with the cap removed). etc.
Search using Google not the DUC forum search. e.g.:
https://www.google.com/search?q=cont...not+responding
(see the Avid Knowledge Base article in the first few search results? You tried everything there?)

If it's more than that then get a used 002 or move to the modern era.
