Hi all,
I just bought a Tektronix 2335 oscilloscope, one minute working, the
next minute the trace is gone. The beam finder does not work. nothing
works. However I do see a flash of a blurry beam when I first turn it
on, but that's it. When opened I see small resistor is burned open
just to the left of q114 off the emitter on the vert out/HV power pcb.
I can't tell what the value is and I don't have any schematics. The
big question is this: What else is gone and why? I don't suppose
anybody has the schematic for this board?? (same as 2336 scope)
Please help if you have ANY ideas!!
