Troubleshooting on Power Supply Section1. No powe supplied to each section (Power lamp not lighQ3. TROUBLESHOOTING CHART(Notices when servicing this unit)oon tight Emitted Diode (tED)The LED used as Pilot Lamp driven by constant cur-rent has characteristics of extreme low reverse break-down voltage (DC 3V) and also it would be easilyinfluenced by discharge voltage from capacitors inpower amplifier section.Therefore, after power switch is turned OFF and lapseof a few seconds, perform the replacement of LED.oNotice when replacing lC1) Do not vent the leads of lC more than 3 times.2) When using a soldering iron, lC should be absolute-ly isolated from current leakage of the iron. lnorder to protect lC against break-down, connect alead wire from the iron to ground (chassis) asshown below. (Fig. 3-1)1-1. AC+30V not supplied to terminal on F-22001-2. AC + 30Vsupplied to terminal E on F-2200+45.5V not supplied to terminal Jon F -2200+45.5V supplied to terminalEon F -22403-2. Troubleshooting on Audio Section1. Quick acting fuse open1-1. fter replacement, f use open again| -1) DC bias current is over 5omA1-2. After replacement, fuse not openI r) DC bias current is not between 30mAand 50mA2. AUX inoperative on F -2400on F -24003. PHONO inoperative3-1. Excessive DistortionF ig. 3-1to chassissoldering ironlead wire3) As lC is extremely weak against heat; use a solder-ing iron as shorter as possible.oNotice after replacing power lCAfter replacing power lC, check DC bias current(30mA ., 50mA) on power amplifier section. If thevalue is under 30mA or over 50mA, the IC must bereplaced again because it may be probably caused oftroubles again.Cause & What to Do1. lmperfect contact of power supply plug2.
