After open, direct high pressure cap, high tension line, line output transformer and so on easy to appear lighter parts, and no obvious signs of flint. Have to fast electricity a try to it, as the analysis is to degaussing coil discharge, high pressure cap and degaussing coil and the sparking discharge tube graphite layer, the grounding line, a scary "snapped" sound. 5DVservice manual download site

Power after high pressure mouth first to discharge (pens and simple method is: use multimeter, one end of the tube field lines or motherboard, touch high pressure inside the cap to discharge) at one end, and remove high pressure cap, found that high pressure circlip and high-pressure mouth badly corroded metal part, and damp, high pressure cap lining burning several questions. Change after high pressure cap and circlip, use water clean high pressure mouth rust that day. Sparking discharge in order to improve the safety performance, avoid high pressure cap, apply adequate amount around the high pressure mouth near 703 silicone rubber, and then buckle on high pressure cap, again by extrusion pressure cap outside introversion, via high pressure of extrusion rubber exudate of cap epitaxial small quantities, wait 10 minutes can use electricity.5DVservice manual download site
