28、 board, it should be +5Vdc. 3.Please check the fuse(F1) if open on psu board 4.Disconnect the cables between PSU and NCORE/NMB board, and then supply the AC(230V) to PSU board, check the voltage of C25 and C928, it should be 320Vdc and 33Vdc, at last please check voltage of J1(it should be 5Vdc). 5.

29、If above voltage are correct, please check impedance for the +5V_SB and +5VD of J3 on NMB board to GND, if the value is normal, and than reconnect the cables. Please check the voltage of pin2 of U39 on NMB board(it should be +3.3Vdc and check the frequency of Y4. 6.If above voltages and frequency ar

30、e correct, please reprogram the FW. 1.Please check the LCD Brightness setting 2.Please check the voltage of J2 on LCD interface board, it should be 5Vdc. 3.If has 5Vdc,please check the frequency of PWM_B/L pin, it should be 78.13KHz. 4.At last please check the LED -A of U7, it should be +8.3Vdc. 5.I

31、f above voltages and frequency are correct, maybe the problem on the LCD module. 1.Please check the connection between NMB board and LCD interface board.(e.g. J24 on NMB board) 2.Please check the voltage the pin 1 of J24(3.3V_LCD) and Pin2 of J24(3.3V_SB) on NMB board No Trigger Out1.Please check th

32、e voltage of the net +12_vcc(it is +12Vdc) and net trigger_out1(it is 3.3Vdc) 1.Please reprogram the FW by Service jack. If it cant be solved, please check following items: 2.Please check the Net +5V_SB (its +5Vdc) and net+3.3V_SB of U39 on NMB board. 3.Please check the frequency of Y4(its 8MHz), ch

33、eck the voltage of pin51 of U40(net NMB_STBY, its 0V),and the pin 5 of J3 is +3.7Vdc on NMB board, this pin is control the M2 relay ON and OFF. The PSU will supply main +5VD to NMB board if the M2 relay is ON. 1.Please check the net HYPEX_ONOFF(its 3.3V) on NMB board, this pin will go to Q1/Q4/Q2 an

34、d then control RL1 ON and OFF. This relay is control the AC main power to NCORE(AMP module) 2.Please check the +/-22V on pin1 and pin2 on PSU board. 3.Please check the +/-12Vdc on the U1 and U3 on PSU board 4.Please check the voltage on the pin1 of J20(it is +12V) , pin 2 of J20(it is 3.3v) on SPK(s

35、peak output board) 5.If above voltages are correct, please check the signal on DAC and PRE OUT section(please see the schematic of NMB for the PERIPH-ADC/PERIPH-DAC1/PERIPH-DAC2) and M10 PSU schematic. Bridge is no output 1.Please check the voltage of the net +5VD(R16) is +5VDC on PSU board, the swi

36、tch S2301 is ON, the net BRIDGE_MODE_DET is 5Vdc go to pin24 of U1 on NMB, and then the net HYPEX_L_RELY is 3.3V to control the RL4 and let the power amp working on bridge mode. 1.Please check the voltage of the net #OC_VBUS_D4(its 3.3V) and net USB_PWREN4(its3.3V). 2.Please check the voltage on the

37、 pin 1A of J5, it should be 5V. 3.If above the voltages are correct, please check the frequency(Y107) is 24MHz when insert flash memory devices. Cant play the music with flash memory devices from USB A jack Power wont turn on, logo LEDs or LCD wont light LCD wont light(but unit can turn on) No displ
