Service Manual
Note: these models machine are the deviation ones of DV317SI, so this service
manual only introduces the circuit different from DV317SI, please refer to “DV317SI
Service Manual” for details.
DV511SI Service Manual
The appearance, decode and power solution of DV511SI are the same with those of DV317; decode
board adds 5.1CH output on the basis of DV317SI; working principle of power board and AV board is the
same with that of DV317SI. Panel, MIC board and subsidiary board adopt new outlook, so PCB board
structure is different, but working principle is the same with that of DV317SI. For the working principle of
decode, power, AV output circuit of this player, please refer to “DV317SI Service Manual”.

2. Working principle
(1) Button function realization: when users are operating the machine, button matrix circuit will
produce a button function code that transmits to the main CPU inside decode chip, CPU performs the
corresponding switch to the function module inside system, and a signal will produce at the same time to
control OSD and panel display part to make the relevant display.
(2) Panel display drive: when the serial data signals sent by decode ship are transmitting to panel
IC (PT6961), IC performs LED drive according to the information send from decode and displays the
relevant content (controlled by software).
(3) Door indicator light control: controlled by decode chip directly.
3. Definition and function of main jack of panel
XS402 is connected to subsidiary panel, with the function of transmitting button control signal
and power indicator light control drive voltage.
XS401 is connected to decode board and the jack that communicates with decode system, in
which IR is remote control signal output pin, +5V is panel power supply.
LEDAT is data transmission pin (dual direction), controlled through LEDST, LEDCK is the
working clock signal input displayed by panel.
FSO is the control pin to panel light by firmware.

2. Working principle
MIC part working principle: after microphone is inserted into MIC left, DET signal on socket changes
from high level to low level to make the mute circuit of decode part and MIC board turn off, no matter
disc reading is available, audio circuit may output normally. If this signal has trouble, microphone will
have no sound when playback pauses. The two-way signals inputted by microphone, after being filtered,
input to pin 3, 5 of U601 separately, and signals after being amplified output from pin 1, 7 of U601. MIC
signals, after U602A mixed amplifying and U602B amplifying again, are outputted by pin 7 of U602 to
decode board for Karaoke signals processing and outputting together with audio signals to fulfill
Karaoke function.
After microphone is unplugged, DET signal changes from low level to high level, Q601 is saturated
on, OK signal is short circuited to ground to prevent interfering rear stage audio output circuit.

DV514SI-2 Service Manual
2.1.1 Block diagram of the player
DV514SI 2 adopts the outlook of DV514SI, and adopts the solution of DV317 series on the basis of DV514,
with the function similar to DV514SI. Decode board adds 5.1CH output on the basis of DV317SI, power board and
AV board are the same with those of DV317SI, only headphone signal socket is deleted on AV board. Panel, MIC
board and subsidiary board are the same with those of DV514SI. For working principle of each unit circuit of this
player, please refer to “DV317SI Service Manual”. Block diagram of the player is shown in the figure 2.1.1.1:

inputted by microphone, after being filtered, output to pin 3 of U601, and signals after being discharged
output from pin 1 of U601 to decode board directly for Karaoke signal processing and outputting

2. Working principle
Realization of button function: when users are operating machine, button matrix circuit will produce
a button function code that transmits to the main CPU inside decode chip, CPU performs the relevant
switch to the function module inside the system, and a signal will produce at the same time to control
OSD and panel display part and makes the relevant display.
Panel display drive: when serial data signals sent by decode chip are transmitting to panel IC
(PT6312), IC performs VFD drive according to the information sent from decode and displays the
relevant content (controlled by software).
Indicator light control circuit: controlled by standby control circuit.
3. Definition and function of main panel jack
XS401 is connected to MIC board, with the function of transmitting button control signal and
standby control signal, panel power supply.
XS402 is connected to decode board and the jack that communicates with decode system, in
which IR is remote control signal output pin, +5V is panel power supply.
DATA is data transmission pin (dual direction), controlled through STB, CLOCK is the working
clock signal input displayed on panel, IR is remote control input pin.
