Circuit Description Index

1. Audio circuit (Circuit diagrams Main PWB 1/1 JACK PWB 1/1)

1.1 Audio input

The audio signal input received from the audio input terminal (JK011) is applied to the pre-amplifier I006 of

2 (L-CH) and 29 (R-CH) through the low-pass filter consisting of R047, R049, R048, R050, C062 and C063.

In this pre-amplifier, controls of Volume, Balance, Bass, and Treble are conducted. The audio signal controlled

at the pre-amplifier is entered in and amplified at the AMP I007 of 9 (L-CH) and 1 (R-CH). Since then, the signal

is to the output jack.

1.2 Audio output

The audio signal is output from the output terminal (P012) of the jack to the speaker system.

2. Power supply (Circuit daigrams MAIN PWB 8/10, 9/10, 10/10)

1. I322:DC-DC converter

A 5V power supply for LCD module, CPU, and logic is generated from the 19V source.

2. I323:3-terminal regulator

A 3.3V power supply for Scaler IC I315, LVDS IC I319, I320 is generated from the 5V source.

3. I330:3-terminal regulator

A 3.3V power supply for SDRAM IC I316, I317, I318 is generated from the 5V source.

4. I324:3-terminal regulator

A 2.5V power supply for Scaler IC I315 is generated from the 5V source.

Q307, I321 ON/OFF control for LCD Module

ON/OFF control is performed for power ON/OFF and also for the power saving sequence.

U170ATA

3. Video input circuit (Circuit diagram MAIN PWB 4/10)

The AC-coupled video signal is used to clamp the black level at 0V).

4. Definition converter LSI peripheral circuit (Circuit diagram MAIN PWB)

I315 gm5020 is the definition converter LSI.

The analog R, G, B signal input entered from the video input circuit is converted into the digital data of video

signal through the incorporated A/D converter. Based on this conversion, this device performs interpolation

during pixel extension. The source voltage for this device is 3.3V, 2.5V and the system clock frequency is

24MHz. The withstand voltage level for the input signal voltage if I315 is 3.3V and 5V.

5. System reset, LED control circuit (Circuit diagram MAIN PWB 3/10)

5.1 System reset

System reset is performed by detecting the rising and falling of the 5V source voltage at I301.

5.2 LED control circuit

Green / amber is lit with the control signal of the LED GREEN and LED AMBER signal pin 15, 12 from I306

(Circuit diagram MAIN PWB 2/8).

6. E2PROM for PnP (Circuit diagram MAIN PWB 4/10)

Page 1Circuit Description

7. E2PROM (Circuit diagram MAIN PWB 3/10)

Data transfer between I305 (AT24 C16) and CPU (Circuit diagram MAIN PWB 2/8 (I302) is effected through

the IIC bus SCL (pin 15) and SDA (pin 16) of I302. The data to be transferred to each device are stored in I305.

l I315 control data.

l OSD related setting data.

l Other control data for service menu.

8. CPU circuit (Circuit diagram MAIN PWB 3/10)

I302 (87C51RD2) functions as the CPU.

The source voltage for the device is 5.0V and the system clock frequency is 24MHz.

8.1 Detection of POWER switch status

The CPU identifies the ON status of the two power supplies. The identification is made when the power supply

is turned off. For example, if the power supply is turned off with the POWER switch, the POWER switch must be

turned on when activating the power supply again. If the power supply is turned off by pulling out the power

cord, then this power supply can be turned on by connecting the power cord, without pressing the POWER

switch.

8.2 Display mode identification

8.2.1 Functions

(1) Display mode identification

l The display mode of input signal is identified based on Table 1.

l When the mode has been identified through the measurement of horizontal and vertical frequencies, the total

number of lines is determined with a formula of  Horizontal frequency / Vertical frequency = Total number

of lines. Final identification can be made by examining the coincidence of the obtained figure with the

number of lines for the mode identified from the frequency. The boundary number of lines in each mode is

shown in Table 2.

l When the detected frequency if the sync signal has changed, the total number of lines should be counted even

through it is rge identified frequency in the same mode.

(2) Power save mode.

This power save mode is assumed when the frequency of the horizontal / vertical signal is as specified below.

l Vertical frequency : 50 ~ 86 Hz

l Horizontal frequency : 24 ~ 92 KHz

l VTOTAL : 1200 or more.

(3) Power save mode.

The power save mode is assumed when the horizontal / vertical signals are as specified below.

l If there is no horizontal sync signal input.

l If there is no vertical sync signal input.

l If the horizontal sync signal is outside the measuring range of gm5020.

l If the vertical sync signal is outside the measuring range of gm5020.
