While those things are powerful, they usually do not solve that sort of problem, at least in my experience.

Generally speaking, there are two scenarios where a degaussing wand doesn't fix things:

1. The wand can't get within close enough proximity to the rim band - requires the CRT to be removed from the cabinet (the labour time involved here makes most sets BER at this stage).

2. The CRT has been dropped and the (fragile) shadowmask is distorted - trashed CRT in other words.
