I recently acquired a D61a, and on first power up I connected ch1, then ch2 to the CAL signal. Both channels do not seem to be triggering properly - adjusting the Trig Level just slows down the display and the Auto Trig doesn't make much of a difference. I have not replaced the filter caps yet, as I am waiting for them to arrive. In the mean time I checked the notorious R95(others have said that this resistor drifts high), but it checked out within tolerance. Has anybody run into this issue? Could it just be the caps? Or is there another problem that is common with these scopes?
