Hi,
I need some help.
I have an HP8565A and I have no Frequency readout neither on the CRT nor on the LED readout.
The problem started a few months ago when the LED readout started to flicker and display intermittent lighting of the segments. Now it just displays 0.0000
I checked the 10V reference and is within tolerance. All voltages on the PSU ar within tolerance too.
Any Ideas were to go from here please.
Thank you in advance
Mans.
