Hello,
I have an oscilloscope which seems to be well preserved but I don't see any output on the screen even when I push beam finder.
I opened it an gave a look inside where there seems to be nothing wrong.I used a multimeter to check that the internal voltage on board is the one that is supposed to be(+30V,-30V,200V,+5V,-5V) and everything is fine.I checked the wires from the circuits to the screen and everything seems to be fine too.While I was playing with the various screen options I found that the graticules are responsive and they become positive(their intensity augments) when I turn the proper option clockwise.
What do you think the problem could be?
thank you all,
naimead
