 Hi advise you check for poor or bulging "electrolytic capacitors" in the power supply secondrys.Also go into service menu & do a Factory Reset.Click on the link (or copy/paste it) Its for "electrotanya" a free site for service manuals.Your model is not listed but i think the Wax 3 chass will be near enough.
