My old faithful 7904 has started to have a little problem with the display.
It will run for hours or days with no problem. Then it will start to drift
the display up and down, this is the trace/s and readouts as well. Note this
is not on oscillation up and down. It will shift up for awhile, then drop
down lower then it should be for awhile. I am talking about a 1/2 CM or so.
Everything is always on screen, it just gets annoying after awhile.
I found I can turn off the readouts and it will stop. Turn the readouts back
on, and it will be fine again for a few hours or days.
Any ideas what might be going on and where to start looking before I tear
BTW Hi Mark Gurries glad to see you on the list.
