My scope (a BK 2160) has gone funky. With no leads connected it shows
what look like a very fuzzy view of a very high frequency oscillation.
It fills about 4 divisions on the screen and is unaffected by changing
any of the front panel controls. Can anyone name someone in the
Boston area who would do a repair and cal?

Thanks, Andy

You could try Hayes Instrument Service although they aren't the cheapest
guys around.

Are you /certain/ you don't have the gain turned all the way up?

Yes, adjusting the gain on either channel doesn't affect the display
at all.

There's a place called Test Equipment Depot, not sure which city it's
in. They MIGHT be able to do it.
