What is the problem with your 2215A?
Is the power supply not working? Tehn google, fault topic is covered
many times.

Other problem? Then let us know more about it.

The display only shows a signal when pressing the "Find beam" button.
Otherwise there is no output.
I think that the horizotal deflection is not working.
I've got a Service Manual for the 2215 but the layout seems to be
different.

Any ideas?

Regards,
Martin

Is the beam intensity turned way down?

No, of course not. :-)

You could remove the scope case,and examine the area where the CRT neck
leads connect to the main PCB;that gives you the general area of the
horizontal output amp,and you can also check top see if a H CRT lead fell
off the CRT neck pin,which happened often enough.

The same goes for the vertical deflection.


Red and green for horizontal,brown and blue for vertical deflection leads
to the CRT.

Then you can use another scope to check for the proper sweep ramp and DC
potentials on both CRT leads.

Addendum;
For a vertical check,you can short the CRT neck pins.
