CRT Problem

You have an easy one here. Your CRT is broken or cracked and has aired. When a CRT has gone down to air, it will arc internally all over the guns or half down to air will produce a strong blue or pink glow internally. When down to air, tube is "shorted" and will build HV and arc internally but no raster and I have seen some tubes that are internally shorted (perhaps not down to air-your case) and by removing the CRT socket will build HV again. Remember, any arcing around the guns indicates your tube has "aired". When first you see this condition, turn set OFF immediately as it is very hard on the sweep circuit (short across flyback) and will ruin the HO tube and/or flyback if left on. Julian
