TROUBLESHOOTING FLOW CHART NO.1 The power cannot be turned on. See FLOW CHART No.2 <The fuse blows out.> Is the fuse (F601) normal? Check if there is any leak or short-circuiting on the primary circuit component, and service it if defective. (IC601, IC602, Q602, D614, D615, D616, D617, T601, R618) Is the AMP+24V line voltage normal?
Page 22 FLOW CHART NO.5 AMP+24V is not outputted. Check D531, D548, C511, C512 and their periphery circuit, and service it if defective. Check if there is any leak or short-circuit on the loaded circuit, and service it if defective. FLOW CHART NO.6 P-ON+6.4V is not outputted.
Page 23 FLOW CHART NO.10 PANEL+24V is not output. Is approximately 22V voltage supplied to the emitter of Q508? Is approximately 24V voltage outputted to the collector of Q505? Replace Q505. FLOW CHART NO.11 PANEL+13V is not output. Replace IC502. FLOW CHART NO.12 LCD-6.8V is not output.
Page 24 FLOW CHART NO.13 P-ON+11V is not output. Is approximately 12V voltage supplied to the base of Q506? Replace Q506. FLOW CHART NO.14 The key operation is not functioning. Re-install the switches (SW101-SW106) correctly or replace the poor switch. Check the switches (SW101-SW106) and their periphery, and service it if defective.
