a. Principle of power supply operating
Adopts switched-mode power supply module TOP233Y of TOPSWITCH company, it can protect
itself from over current, overheating, and short-circuit, etc. This circuitry mainly stabilizes at +5V,
and fluctuates within a permissible range, such as +5V, VA+, VA-, +3.3V and -24V. Please pay
attention to the high voltage inside the white paint of PCB while repairing. When using an oscillator
to measure this portion, an isolated transformer must be connected.
Circuit of power supply may output the following power sources:

b. Troubleshooting and service
a). If +5V voltage varies out of the permissible range, check whether sampling resistance R8 and
R9 (R422 and R423) are eroded, and whether the 1st pin of regulated voltage reference U3 (U402)
TL431 is at 2.5V. If the deviation is over 0.1V, TL431 is eroded and shall be replaced. During
maintenance, the +5V sampling circuit, i.e. D9, R5, R8, R9 and U4 (D415, R419, R422, R423, R421
and U403), shall not be open, otherwise, it may result in high voltage and damage other circuits on
the rear pole.
b). If all the output voltage is 0V, and a voltage of 300V or so exists at the positive pole of C8 (C403),
check whether +5V, +8V, -8V, -24V and +3.3V are short (whether Q401, Q402 and Q403 are open).
c). If +3.3V of AC1-AC2 is 0V and no display on VFD, check whether D6 (D408) is open. If the ribb
on wire is not in good contact, replace the corresponding ribbon wire.
Note: Components in the brackets are of TDE-F70/F71.
2. Troubleshooting and Service of the Loader
pole of Q1 and Q2, and whether U2 and adjacent parts are damaged or weld falsely.
d). If the above parts are normal and no laser emits, replace the loader.
b. Read no disc
a). Check whether the ribbon wire from 24P to loader is in good contact.
b). Check whether the RFO signal of the 10th pin of CN6 is transmitted to the 96th pin of U1.
c). Check whether laser voltage (about 2V for VCD and 2.2V for DVD respectively) exists at the C
pole of Q1 and Q2, and whether the voltage is normal.
d) Check whether U1, U2 and adjacent parts are damaged or weld falsely.
e). If the above parts are normal, replace U1 or the loader.
c. Read DVD discs only or read other discs beyond DVD only
a). Check whether the ribbon wire from 24P to loader is in good contact.
b). Check whether laser voltage of 2V outputs at the C pole of Q2, and whether the 125th pin of U1
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.
g). When U5 works normally, check the connection between U8, U9 and U3. If abnormal, replace U8
or U9.
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.
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 part
a. Normal picture, no sound a). Firstly, check whether the +8V and -8V power sources for the operational amplifier IC U12~U14 are normal. 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. c. Pop noise during ON/OFF Check whether the MUTE signal line on the output board is broken, then check whether Q18, Q19, muting tubes and adjacent parts are damaged or eroded.
6. Troubleshooting and service of KARAOKE part a. Microphone with sound but no echo a). Check whether the level of the 1st pin of U1 on the KARAOKE board is +5V. If not, check whether JP1 is damaged. b). If the voltage is proper, check whether there is anything wrong with the adjacent parts of U1. b. No sound of microphone a). Check whether the microphone indicator on VFD lights. If the level of C pole of Q16 is low, the C and E poles of Q16 are short. b). Check whether the power source of U2 on the KARAOKE board is normal and with microphone signal output. If not, check whether the parts of input circuit for microphone jack are damaged and check whether the microphone jack is rusty or short.
7. Full screen display or no display on VFD a). 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.
