It's been a while, but as I said, those power connections can cause all
sorts of odd issues. Just carefully & completely re-flow them with some
SN63 material (if you have it, else SN60 will do) and know that it's one
issue you won't have to face.

IIRC, one unit with that problem had flicker, static in the speaker and
also system instability. It was either an SE/30 or a Plus, I had several of
each model at the time.
