Re: HP 3585B Spectrum Analyzer How to start diagnosing "No Horizontal sweep" problem
There is a fuse inside the unit on one of the boards. It supplies 12v to the horizontal oscillator. If your flyback is bad, that fuse will blow and you will have no display on the CRT. The board is

Re: HP 3585B Spectrum Analyzer How to start diagnosing "No Horizontal sweep" problem
