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.
