After opening the cover, high pressure, high voltage wire, direct cap line output transformer easy ignition position, no obvious signs of fire. Had to give the rapid energized a try, as the analysis that is cap high-voltage discharges to a degaussing coil, also degaussing coil and to imaging tube graphite layer, the grounding wire sparking discharge, issued by the "flap" sound scary.
Power to high-pressure nozzle discharge method is simple: with multimeters, one end is connected with the imaging tube outer wire or board, one end of the touch inside the high-pressure cap discharge), then remove high-pressure cap, found high pressure circlip and high-pressure nozzle metal parts of the serious corrosion, and damp, high pressure in the inner wall of the cap has a burn mark. Replace the high-pressure cap and a circlip, with rust cleaning the mouth clean and high pressure water. In order to improve the safety performance, avoid high pressure cap sparking discharge, daub appropriate 703 silastic around the pressure near the mouth, then buckle pressure cap, from the inside outward extrusion pressure cap, the exudation of the rubber extrusion pressure cap extension little then, wait ten minutes can electricity use.
