[time-nuts] FW: HP-5732A operation with no CRT display.

[Lester Veenstra]

Dave:    I have a "not working, parts only" unit coming.
I will see if A17 is working on that unit.
If I get one working, I think I can signal trace to the problem unit, using the good one as reference

Lester,
I think looking at the parts list in the Service manual from Artek it’s a bought out all in one unit.  If I recall the BOM has one line item.  
Have you checked with Walter at Sphere? He has the next PN in the sequence which is a Sony Color display.  Or check with Newscope for a LCD replacement.  

My new to me 5372A has a bright screen but I noticed it glitched a few times yesterday.  The size changed for an instant a couple of time but other wise is working.

As I recall, this was from the era where HP still provided full "real" manuals with all the schematics etc. The exception sometimes is if the entire display is an OEM unit, treated as a single component, and minimally documented. I don't recall much of the guts, as it's been a lot of years since I saw the inside.
