I might suggest joining the "wavetechtestequipment" Yahoo group: Some people there can help you get a copy of the manual.
As far as the power supply being bad: I would first unplug the power for the monitor and see if it powers up. A very common problem is that some of the electrolytics in the monitor (especially under the HV compartment's shield) will leak and short things out, preventing anything else from working. Also, if you have not yet replaced every single one of those surface-mount aluminum electrolytics that are found on many of the boards (the shielded plug-in modules as well as the non-computer plug-in boards on the back) you really should before the thing fails and/or traces are eaten away. (There are 116 of those capacitors, IIRC, and every board that had caps replaced should be washed clean and thoroughly dried to remove the leaked electrolyte.) 73, Clint KA7OEI > I am in need of the service manual for my Schlumberger 4031 service > monitor.
