Check to see if the connectors on the circuit boards haven't gotten corroded. Pulling and pushing back down on the connectors may clear some bad connections. Which may clear the problem.
Lots of connections, and IIRC the connector surfaces are just tin. _____________________________ Gun Control is using both hands

Conrac monitors were used extensively by the DoD in Automated Test Stations - the Navy used them in the CAT-IIID and RadCom stations (both Grumman, used to support the bygone A-6 Intruder and F-14 Tomcat aircraft.
I fixed a total of two - one had no G-2 voltages (was an open 180K resistor) and the other had a nasty arcing in the focus lead as it left the HV cage. A little RTV Silicone sealant fixed that. There were Grumman supplied, original Conrac manuals for the monitors - the Navy never produced any manuals themselves. Very durable - they survived the vibration and G-cycling produced by the catapaults on an Aircraft carrier, but the ship's degaussing system used to give them hell - hence the manual degaussing switch on many models. If a Google search comes up with nothing, I'd be hard pressed to tell you where to get a manual. Good luck - those monitors are solid, American made and sharp! Cheers,

I've been lucky, I was able to find a manual for the monitor. I haven't had a chance to put the monitor back on the bench to be checked over, and someone else I think suggested something similar. This monitor is very modular in its construction, so lots of connectors everywhere. I'll be trying it again real soon.

Well it didn't work out for cbenham. I discovered that I had SNA not ENA manuals. So that means SOMEONE out there must have an ENA manual. Come on, its not like Conrac didn't provide monitors for EVERYONE back in the day. Anyway, I'm putting the call out for ENA manuals, if anyone has one please contact me or cbenham.
