1.1Principle of Power Supply Operation
This appliance adopts a switched-mode power supply, which is assembled with the TEA1523P
power switch module from Philips and is capable of protecting itself from over-current, over-voltage,
over-heat and short-circuit. The circuit mainly stabilizes a t +3.3v and fluctuate within a permissible
range, such as +5V, +12V, -12V, +3.3V and -24V. Please pay attention to the high voltage inside
the white silkscreen with the mark CAUTION on the PCB while repairing. When using an
oscillograph to check the circuit,an isolated transformer must be connected.
1.2Troubleshooting and Service
l+3.3V voltage varies out of the permissible range
Please check whether the sampling resistor R324 and R325 is eroded, and check if the voltage
of the first pin of the regulating fiducial IC U303 (TL431) is 2.5V. If the deviation is over 0.15V,
then TL431 is defected or eroded and needs to be replaced. When repairing, do not loop +3.3V
sampling circuit, that is, do not open-circuit D313, L306, R324, R325, R322, U302 (PC123Y) and
U303; otherwise, the output voltage will be too high and will damage the subsequent circuits.
lAll the output voltages are 0V and the voltage of the anode of capacitor C305 is over 150VCheck
whether +5V, +3.3V, +12V, -12V and -24V are short. Check if pin 3 of U301 has 100KHz vibrating
signal, if not, then U301 is eroded.
l+12V and +5V voltage are not normal, while other voltages are normalCheck whether D309,
R315, L303 and ZD303 are open or short, whether C315, C316 and C317 are short or
leak electricity. Any problem of these components will result in abnormal +12V and +5V voltage.
Open-circuit or short-circuit of D312, L305, ZD305, R319 and Q304, and electricity-leakage and
short-circuit of C324, C325, C326, C335 and C328 will result in abnormal +5V voltage.
l-24V and AC1-AC2 voltage are not normal, while other voltages are normalCheck whether R311,
D307, D308, R313, R312 and R314 are open or short, whether C312, C313 and C314 are short
or leak electricity.
lAll output voltages are under permissible range (refer to 2.2 of Chapter one)Check whether ZD
302, C308 and R303 are defected or eroded. If +3.3V output is normal and other voltages are
under range, check if the appliance is in standby mode. In standby mode, it is rational that all
voltages except +3.3V are not normal. If in playing mode, +3.3V output is normal, 5V output is
0V or too low, please check whether +5V is short-circuit and whether R320, Q305, ZD305, D312,
R319, C324, C325, C326, C328 and C335 are defected or eroded.

is at low level.
c). Check whether the pins from the 1st to the 38th of U1 and adjacent parts are weld falsely,
damaged or erode.
d). If the above parts are normal, replace U1 or the loader.
3. Troubleshooting and service of decoding part
a. No video, no audio, no display on VFD, and no operation of keys
a). Check whether the power sources of the decoder board are normal.
b). Check whether there is 27MHz signal output. If not, X1 crystal and adjacent parts are eroded or
damaged.
c). Check whether there is 81MHz signal output at R64. If not, check whether there is short circuit,
false welding or alien substance for audio D/A circuit U5 and SDRAM U8 and U9.
d). Check whether the reset circuit composed of C7, R37 and D1 is normal (constant 0V after tens
of milliseconds of high level). If it is at low level constantly, C7, R37 and D1 are damaged.
e). If the reset level is normal, check whether the chip selection signal, address and data of the 12th
pin of U5 are normal.
f). Check U10 that whether the data of pins from the 1st to the 8th, hsync and vsync signal of the
10th and 11th pins, and 27MHz signal of the 29th pin are normal, and whether C162 and R68 are
normal. If not, replace U10.
4
g). When U5 works normally, check the connection between U8, U9 and U3. If abnormal, replace U8
or U9.
h). Replace the main chip U3 after making sure no damage to the adjacent parts and no short circuit
or false welding for the circuit board.
4. Troubleshooting and service of video part1). Normal sound, no video picture

pins, and 27MHz signal of the 29th pin are normal, and whether C162 and R68 are normal. If not, replace U10.
2). Abnormal color of the video picture
a). If there are horizontal or vertical streaks, or improper color appears on the picture after reading a disc, the
U3 decoding servo chip on the decoder board or U6 EEPROM may be in problems.
b). Check board whether the 3.3V and 2.5V power sources are normal, whether the ripple factor is too high,
and whether the data wire of Y(0, 7) between U3 and U10 is normal.
c). Check whether the video filter network circuit on the decoder board works normally.
5. Troubleshooting and service of audio parta. Normal picture, no sound

b). Check whether the C poles of muting tube Q14, Q15, Q22, Q23, Q21 and Q20 are at low level constantly.
If so, the above tubes are not in good conditions.
c). Check whether the output of C poles of Q18 and Q19 are at high levels constantly. If so, Q18 and Q19 have
been broken down, or C209 are short.
d). Check whether the six audio signal lines on the 20P ribbon wire from decoder board to output board are in
good contact. If abnormal, replace the ribbon wire. Check the signal reaching the input of U12~U14. If the input
is normal while the output is not, replace the operational amplifier IC.
e). Check whether the signals of the 17th, 19th, 21st, 23rd, 25th and 27th pins of U5 on the decoder board are
normal. If not, check the signals of the pins from the 2nd to the 7th. If the clock signals of ACLK, ABCK and
ALRCK output by U3 are normal after R130, RN2 and R131 are disconnected, replace U11.
b. Distorted audio and loud noise
a). Firstly, check whether the +8V and -8V power sources for the operational amplifier IC U12~14 are normal.
b). Check whether the muting tubes are in good conditions.
c). Check whether the signals of the 17th, 19th, 21st, 23rd, 25th and 27th pins of U11 on the decoder board are
normal. If not, check the signals of the pins from the 2nd to the 7th. If the clock signals of ACLK, ABCK and
ALRCK output by U1 are normal after R130, RN2 and R131 are disconnected, replace U5.

Check whether Q16 and Q17 are open or not in good contact.
d. self-excitation once KARAOKE is turned on
Check whether the adjacent parts of U1 on the KARAOKE board are damaged.
7. Full screen display or no display on VFDa). Full screen display on VFD is often caused by abnormal -24V bias voltage. Check whether D5, C19 and R17
are disconnected.
b). If there is no display on VFD, firstly, check whether the filament lights in red. If not, and there is no 3.3V
voltage difference between AC1 and AC2, check whether D6, C9 and R21 are damaged. If the filament is not
red, while 3.3V voltage difference exists between AC1 and AC2, replace VFD.
c). If -24V and AC1-AC2 voltage are normal, check whether there are CS, DATA and CLK signals from CN301
on the front board. Then replace PT16312 (PT6554) under the condition that both of the above mentioned are
normal.
8. No operation of some keys on the front board, disordered display on VFD
Check whether the welding from the 12th, 13th, 15th pins of U301 to the 37th pin is in good conditions.
Check whether D301~D303 on the front board are damaged, whether circuit is disconnected, and whether R309,
R310 and R311 are open.
9. No sensitive remote reception, or no reception from the remote handset
Check whether the power source of the remote sensor is proper.
Check whether the remote handset is in good operation mode.
Use an oscillator to observe whether there is output wave from the 1st pin IR of the sensor after each pressing
of keys on the remote handset. If the remote handset is good, while no output from the sensor, the sensor is
damaged.
10. The machine can not be turned on or off
If the machine can not be turned on or off after pressing the STANDBY key on the remote handset and the
POWER key on the front board, replace the main chip U3.
