Repair Procedure 1) Remove CB201, CB202 and CB205. (Power (1) P.C.B.) Then the power supply circuit and the power amplifier circuit will be disconnected. 2) Repair the power amplifier as described below. (Main (1) P.C.B.) Replace the defective parts. Whether the major parts are defective or not can be checked as follows. Remove 3 screws fixing the heat sink to the rear panel and 4 screws fixing the support P.C.B. to the rear panel. FET (Q16~19, Q22~24): Measure the resistance value between GATE and SOURCE to determine whether a failure exists or not. If the measured resistance value is close to 0Ω, a failure exists. If the measured resistance value is close to the value of the resistor connected between GATE and SOURCE, no failure exists. Remove 3 screws fixing the Main (1) P.C.B. to the support P.C.B. TR (Q1~4): Check DIODE characteristics between BASE and EMITTER or between BASE and COLLECTOR to determine whether a failure exists or not. Check the operation as follows. a. Prepare a stabilized DC power source equipped with +30V and -30V outputs. b. Connect +B, -B and GND output terminals of the stabilized power source to +B, -B and GND lines of the power amplifier. c. Connect the terminal of the oscilloscope to the circuit between q in the figure and GND. d. Remove CB1. (Main (2) P.C.B.) e. Connect the output of the signal generator to the circuit between the lead on the (-) side of C1 and GND. f. Set the frequency of the signal generator to the 100Hz sine wave and the output level to the minimum level. g. Turn on the stabilized DC power source. h. Raise the output level of the signal generator gradually and check the output waveform on the oscilloscope. i. If nothing abnormal is found with the waveform until the output level reaches 40Vp-p, the check result is OK. After operation check Connect CB1. 3) Repair the SW power supply section as follows. (Power (1) P.C.B.) Follow the instruction described below to avoid any danger. High voltage maintained in C209 and C210 even after the power is turned off is dangerous. It is necessary to force this electric charge to be discharged before starting the repair work. For such forced discharge, connect a resistance of approximately 100Ω/5W to each of both terminals of the capacitor. Then check to make sure that the voltage between the capacitor terminals is 0V. Replace the defective parts. Whether the major parts are defective or not can be checked as follows. TR (Q202~205): It is highly possible that a failure occurs due to a short between COLLECTOR and EMITTER. R216, R217: It is highly possible that a failure occurs due to an open circuit.

Connect CB205. b. Connect the probe of the oscilloscope between TP201 and TP202. c. Turn on the power switch and the STANDBY/ON switch on the front panel. d. Check the waveform on the oscilloscope and adjust VR201 so that a = b is obtained. Permissible range: a/b = 1.0 ± 0.1 CAUTION Electric potential is always applied to the ground side of the oscilloscope. Be careful so that no other part comes in contact with it. Caution for operation check of the SW power supply section and the power amplifier As a high voltage is applied to the SW power supply section and the power amplifier, be careful not to receive an electric shock.

Devices required Signal generator (100Hz sine wave) 8Ω or 6Ω load resistor Oscilloscope (dual trace type) Connection 1) Connect the output signal from the signal generator to the input terminal of YST-SW800. 2) Disconnect the connector terminal connected to the speaker unit and reconnect it to the load resistor. 3) Connect the HOT side of the oscilloscope CH1 probe to the point A or B indicated in the figure and the GND side to the GND of the main unit. 4) Connect the oscilloscope CH2 input to the red side of the connector cable, which is connected with the load resistor. At this time, the GND terminal of CH2 must be left unconnected. Setting 1) Set the signal generator to the sine wave, 100Hz and minimum output level settings. 2) Set the volume of YST-SW800 to the minimum position. 3) Turn on the power to YST-SW800. 4) Adjust the output level of the signal generator and the volume of YST-SW800 so that the output level observed at oscilloscope CH2 is 70Vp-p. Waveform observation With the settings made as described above, observe the waveform obtained at CH1 for judgment. Normal Abnormal +B or GND level Becomes constant Abnormal -B or GND level Becomes constant G Confirmation of AUTO STANDBY operation Setting 1) Turn off the power switch. 2) In order to shorten the time required for operation check; connect a 10kΩ resistor at both ends of R162 on the MAIN (2) P.C.B. 3) Connect the output signal from the signal generator to the L/MONO terminal of YST-SW800. 4) Set the signal generator for the sine wave of 100Hz, 8mV. 5) Turn on the power switch. Confirmation 1) Set the AUTO STANDBY switch to the LOW position. 2) Turn on the STANDBY/ON switch. The display LED lights up (green) and its color changes to red after 5 to 10 seconds. 3) Turn off the STANDBY/ON switch. The display LED goes off. 4) Set the AUTO STANDBY switch to the HIGH position. 5) Turn on the STANDBY/ON switch. The display LED lights up (green) and its color remains unchanged even after time have elapsed. 6) Turn off the STANDBY/ON switch. The display LED goes off. After confirmation 1) Turn off the power switch. 2) Disconnect the 10kΩ resistor connected to both ends of R162. www. xiaoyu163. com QQ 376315150 9 9 2 8 9 4 2 9 8 TEL 13942296513 9 9 2 8 9 4 2 9 8 0 5 1 5 1 3 6 7 3 Q Q TEL 13942296513 QQ 376315150 892498299 TEL 13942296513 QQ 376315150 892498299 http://www.xiaoyu163.com YST-SW800 YST-SW800 8 G Schematic Diagram G Test Points Q18 Q16 Q22 Q24 Q39 Q25 Q23 Q17 Q19 – B GND + B Main (1) P.C.B DC 50mV to 250mV Point A Point B IDLING CURRENT ADJ.
