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”.

1.3.1 Panel control circuit

1. Panel control circuit block diagram is shown in the figure 1.3.1.1:

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.

1.3.2 MIC circuit

1. MIC circuit block diagram is shown in the figure 1.3.2.1:

Figure 1.3.2.1 MIC circuit block diagram


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.

4.2.1 MIC circuit

1. MIC circuit diagram is shown in the figure 4.2.1.1:

Figure 4.2.1.1 MIC circuit block diagram


MIC part working principle: after microphone is inserted into MIC left and signing, MIC signals, after

being amplified by U601A, are compared through comparator U601B, DET signal changes from low

level to high level to mute circuit of decode part off, no matter disc reading is available, audio signals

may output. If this signal has trouble, microphone will have no sound when playback pauses. Signals

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

together with audio signals to fulfil Karaoke function.

2. Working principle: H_L/H_R signal of audio output end is sent to the headphone amplifying circuit

of MIC board through Xs603, headphone amplifying circuit is mainly composed of U603 (TDA1308).

TDA1308 pin functions: pin 1, 7 are output pin, pin 6, 2 are input pin. After being amplified, audio signals

directly output to headphone socket (JK601).

4.2.3 Panel control circuit

1. Panel control circuit is shown in the figure 4.2.3.1:


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.
