I PS CIRCUIT BOARD REPAIR GUIDE
1. Applicable Circuit Board
This guide is applicable when repairing the circuit board specified in the table 1-1.
Table 1-1
Model Circuit Board Part No. Destination Power Supply
XP7000 PS70U WF397200 U/T AC 120 V
PS70H WF397300 H/B/K/O AC 230 V
PS70A WF397400 A AC 240 V
XP5000 PS50U WF397600 U/T AC 120 V
PS50H WF397700 H/B/K/O AC 230 V
PS50A WF397800 A AC 240 V
2. Electrical Performance
2-1 Preparation (See page 51)
· Connect the PSW circuit board (XP7000=WF400100, XP5000=WF400200) to CN403, CN404 and CN405.
· Connect J401 and J402, or short-circuit CN406 and CN415 (for H/B/K/O destination). After repair, make these connections
to its original state.
· Adjust the power supply voltage suites each circuit boards. Refer to the table 1-1 above.
2-2 Voltages of Each Part (See page 51)
The output voltage is normal if it is in the range specified in the table 2-1 when turning the power on.
Table 2-1
Model Measuring Item Measuring Part Output Voltage (DC) Load Resistance
U/T/A H/B/K/O
XP7000 +B W406-W407 approx. +141.4 V approx. +143.5 V 22 k-ohms, 3 W
-B W407-W408 approx. -141.4 V approx. -143.5 V 22 k-ohms, 3 W
+15 V CN408 1-2 pin approx. +15.0 V approx. +15.0 V 10 k-ohms, 1/4 W
-15 V CN408 3-2 pin approx. -15.0 V approx. -15.0 V 10 k-ohms, 1/4 W
XP5000 +B W406-W407 approx. +113.1 V approx. +124.3 V 22 k-ohms, 3 W
-B W407-W408 approx. -113.1 V approx. -124.3 V 22 k-ohms, 3 W
+15 V CN408 1-2 pin approx. +15.0 V approx. +15.0 V 10 k-ohms, 1/4 W
-15 V CN408 3-2 pin approx. -15.0 V approx. -15.0 V 10 k-ohms, 1/4 W
Note: The output voltage may be out of the range if it is measured without the load resistance or the power supply voltage
differs from the specified in the table 1-1.
2-3 Discharge (See page 51)
To prevent the electrical shock (discharge of the electric charge from the capacitor), discharge electricity between the follow-
ing part when handling the PS circuit board.
· Between the positive (+) and negative () terminals of C420 and C421. If you have left the unit for 10 minutes or more after
turning the power off, you do not have to discharge.
· Between W406-W407, and W407-W408.
· Between the terminals of C402.

3. Example of Repair
All DC voltage is not output from secondary side.
3-1 Instruction
Follow the instruction below. (See section 3-2 and diagram 3-3 on page 64.)
1 Check the resistor value of R410 and R411 (6.8 ohms, 5 W).
If opened, replace R410 and R411.
2 Check the resistor value between C-E of Q406 and Q407.
If short-circuited or the resistor value lowers by several values (ohm), remove Q406 or Q407. Also replace IC402 because
it is broken.
3 Check the resistor value of R421 and R422 is 10 ohms.
If opened or the resistor value increases, replace R421 and R422.
If short-circuited or the resistor value is extremely small, replace D409 and D410. After replacing D409 and D410, check
the resistor value again.
4 Check the resistor value of R420 is 4.7 ohms.
If opened or the resistor value increases, replace R420.
5 Check the resistor value of R431 and R432.
If opened or the resistor value increases, replace R431 and R432.
6 Check the resistor value of F401.
If opened, replace F401.
7 After checking items 1 to 6, put the AC power and check the waveform between pin 1 (LO) and pin 2 (COM) of IC402 with
oscilloscope. Check the measured waveform is the recutaugular wave (0-15 V) around 70 kHz.
If the measured waveform is abnormal, check the output of IC403 (3-pin regulator) is +15 V.
If the output is less than +15 V, replace IC402 and check the waveform again. If IC402 is already replaced, replace IC401.
* When measuring the waveform, short-circuit PR401.
8 Check the "2. Electrical Performance" is satisfied. If satisfied, repair is finished.

XP7000/XP5000
3-2 Repair Flowchart
Check the primary side circuit.
Note: Check and repair must be done carefully, otherwise the electrical shock may be caused.
START
Turn the power off.
(Disconnect AC plug from the wall outlet.)
Discharge (*1)
Between ± terminals of C420 and C421

Between terminals of C402
1 Check R410 and R411 resistor value.
NO
R410, R411 = 6.8 ohms? Replace R410 and R411.
YES
2 Check Q406 and Q407 C-E resistor value.
Q406, Q407 C-E NO Replace Q406 or Q407.
Resistor value 0 to several ohms? (0 to several ohms) Replace IC402.
YES
3 Check R421 and R422 resistor value.
NO R421, R422 SHORT
R421, R422 = 10 ohms?
OPEN or SHORT?
YES OPEN
Replace R421 and R422.
Replace D409 and D410.
4 Check R420 resistor value.
R420 = 4.7 ohms? NO
Replace R420.
YES
5 Check R431 and R432 resistor value.
(Secondary)
NO
R431, R432 = 2.2 ohms? Replace R431 and R432.
YES
A
*1) To prevent the electrical shock, be sure to discharge electricity from the capacitor.
Discharge is not necessary if you have left the unit for 10 minutes or more after turning the power off.
