Hello All,
I'm trying to repair a oscilloscope I have. The problem started gradually and now will not power up.
Its a Tektronics 2246 100 MHZ oscilloscope. I have the factory repair manual and schematics, but this problem is not covered in the manual.
Here is what happens. When I turn on the oscilloscope, I hear a clicking from a relay. It clicks over and over and the oscilloscope won't power on. It used to click a couple times, then it would power up. So I'm looking for some kind advice on what might be wrong. I'm thinking since it started gradually then stopped one day, perhaps its a filter capacitor.
If you have some advice...I'll all eyes.
George
