Default Re: Sharp MZ-80K help needed on repair

Make sure the monitor circuits are clean of dust that tends to accumulate on the HT circuits before you do anything else in that area. Take care as they can hold charges at high voltage even after being powered off for quite some time. An insulated paintbrush is useful for removing the dust.
