TROUBLESHOOTING FLOW CHART NO.1 The power cannot be turned on. Is the fuse (F1601) normal? See FLOW CHART No.2 <The fuse blows out.> Check if there is any leak or short-circuiting on the primary circuit component, and service it if defective. (D1202, D1205, D1208, IC1201, T1201, R1202, R1203, C1202) Is the AL+5V line voltage normal?
Page 25 FLOW CHART NO.5 AL+5V is not output. Check C1102, D1102 and their periphery circuit, and service it if defective. FLOW CHART NO.6 PANEL+24V is not output. Check C1725, C1727, C1728, D1714, D1715 and their periphery circuit, and service it if defective. FLOW CHART NO.7 P-ON+12V is not output.
Page 26 FLOW CHART NO.9 No operation is possible from the remote control unit. (Operation is possible from the unit.) Check AL+3.3V line and service it if defective. Replace the IR Sensor CBA Unit or the remote control unit. Replace the IR Sensor CBA Unit. Replace Digital Main CBA Unit.
