[time-nuts] HP-53132A Faded and flickering display

[Tom Knox]

The replacement display board is available for about $550. The display itself may be available if you could find the part number for about $125, but Agilent WILL NOT give the raw display part number out. I ran into this same problem with the 3458A and was finally able to find the number and order some. Does anyone on the list have the raw display part number? There is also a small chance the problem is in the HV module. Perhaps going straight to the display vendor.

> Dear Group,
> 
> Good morning! I just got my first HP-53132A frequency counter and Prologix GPIB-USB converter. Now I can do some measurements and I am excited about it.  Everything looks promising. Condition of the instrument on the outside is like new, controls responsive and no fading in lettering at the buttons. Connectors are not worn or damaged, original connectors. The unit has been tested and works OK, probably not with adequate calibration but that is not an issue now, I can always calibrate it later.

> What worries me is the display. Even though being an Agilent built unit, it has probably more hours on it than a seldom used HP built unit. The flourescent display is fading, not all the digits show consistent illumination levels. The left-most digits show some flickering at some of their segments. It is readable in the end, but I am terribly disappointed about it. 
> 
> Does anybody know if there is a cure for this? Or should I start saving for a better unit.

> I am not afraid of the screwdriver or the soldering iron if someones suggests a display overhaul. Thank you!
