Hello everyone, I got this oscilloscope from my university, when they were changing the old ones with new digital oscilloscopes.
And so, to not be thrown on the garbage I thought that as electronic hobbyist it will be good for me too. The guy that gifted the oscilloscope to me tested it in front of me and when he was testing it everything was working fine.
He mentioned that I will only have to clean it up from inside from the dust and it will be ready to go. So I returned happy at home with my new old analog oscilloscope.
Forgot about it for about an year.
And when I turned it on lately the electron beam on the monitor was not showing at all, I could not find any dot at first place to form a beam.
So here I am, asking for help. What it can be? It was not touched for an year and it worked when the guy showed it to me. Could it be me, not finding the dot, because I am new to this type of oscilloscopes?
I have searched for a button that shows the dot on the center of the display in order to know to start bringing the dot up or down, but did not found such button on my oscilloscope.
Can I make some diagnostic to find the problem (if there is one) ? Please help me, it is a good oscilloscope, two channel and I want to start using it.
