Page 8: Display
Measure the voltage on display connector (J8). The measured value should be above 9V. If the voltage is correct use a reference display and if this operates properly the problem is caused by the display assembly. Yumizen G400 - Display... -
Page 9: Touch Screen
Pin 15 (Chip Select) must be on ground potential and the voltage must be fallen to ground potential when the screen is touched. You need to check whether there is digital communication at position IC 12 when the screen is touched. Yumizen G400 - Touch screen... -
Page 10: Printing
There should be 9 V at pin 1 and 4 of the U4 IC which controls the burning. You should be able to measure 9 volts at pin 5, 6, 7 and 8 of the U4 IC Yumizen G400 - Printing... - Page 11 If the measured voltage is different then check if the control signal appears at the base of the T1 transistor. If the printer complies with all these measurements but it still does not print, check the instrument with a reference printer. Yumizen G400 - Printing...

Page 12: Date/Time
32.7 kHz at pin 7 of the U3 IC. Set the current time, save it and switch the instrument off and on again. Wait for 1-2 minutes and check that the time displayed by the instrument is the same as the real time. Yumizen G400 - Date/Time... -
Page 13: Measurement Result, Calibrations
It is worthwhile doing a software update on the instrument, and then checking if the instrument is working properly before replacing the EEPROM-s. If the EEPROM-s are replaced you will have to press the “Setup defaults” button in the SERVICE menu. Yumizen G400 - Measurement result, calibrations... -
Page 14: Mixer
If there are no square wave signals check that the control is arriving at the U19 input. If there is control at pin 2, 6, 13 and 9, and there are no breaks in the coils then the U19 controller is defective. Yumizen G400 - Mixer... -
Page 15: Temperature Measurement
. You can measure the output voltage at pin 1 of the U20 circuit. If the measured value is not appropriate on the basis of these parameters then there may be a software fault. Yumizen G400 - Temperature measurement... -

Page 21: Serial Connection (Rs-232)
The receiver should support zero modem connection. The serial cable used for communication must be in faultless condition. Check the settings needed for communication. The settings of Yumizen G400 and the receiver must be identical. The Yumizen G400 RS-232 settings are as below: Serial line basic values... -
Page 22: Usb Connection
■ Restart the PC operation system, then switch on the Yumizen G400 and connect it to the PC. If the PC still does not recognise the Yumizen G400, check the PC operation system, whether it supports USB connection. If there is still no connection, check the Yumizen G400 as described in the The instrument does not detect the pendrive chapter. -
Page 23: Measurement Position Signal
PCB. You must measure voltage on pins 15, 1, 2, 3, 4, 5, 6 and 7 of the U17 IC, if no signal is measured on these pins, then the U17 IC has probably failed. Yumizen G400 - Measurement position signal... -
