On the off hand chance that your beam finder is also broken or the trace is
SO FAR OFF screen that the beam finder won't find it, try shorting the CRT
vertical plates together right at the CRT and see if that gives you a trace
or not. It should (if your sweep is running and the horizontal amp works).
This should cause no damage to the instrument if you don't brush one lead of
the shorting wire against ground as you do this . . .

Hi,
Can anyone help with the fault on this one? I have readout but no
trace on screen, this is the same on the beam find switch so it
appears that the trace is not there, not just off screen.
Thanks,
John.
