Well, last a long time... I've found several scopes. One Philips (with
two X inputs) sometimes doesn't give output. Another one (X/Y, 19"
unit, quite big) never gives output, and one biggy (19", with weird
inputs (X, Y, Z)) gives a very strange effect, it keeps in the middle
with fluctuations in one direction (adaptable with knobs). Do you
people have any clue of what could be wrong with these machines? And
is it 'safe' to fix them when they're connected?
