Monitor works but it goes into shutdown after 5 minutes , b plus is at 183 volts. Dont know how it runs at all. Anyone have a manual or schematic or send a link to one for k7500 p793
 
Need to put the bulb parallel the B+ test point

if the voltage drops to the run voltage or adjust.

You need to move to the Horizontal section.

If so then you need to check for voltage on the collector of the Horizontal

driver transistor if low check the Horizontal drive transformer for a open winding.

Or bad connection in the area.

A combination of the two circuits with no load will make the B+ close to what it is

on the primary side of SMPS, having no regulation for the B+.

Check it out.
