    5、Work Principle The product mainly handles with video signal, such as RF (cable TV), CVBS(composite video), S-VIDEO(Y/C signal), YPbPr(progressive video), SCART, DTV signal, VGA and HDMI, as well as audio signal amplifying output. AV includes S-VIDEO and CVBS. In addition, it can input VGA and other signals to realize PIP function. Because the product is comprised of three boards, the work principle will separate into three parts as follows: 5.1、Work Principle of Power Board...
  • Page 15 current is limited, and the 380V voltage of PFC will descend. Actually, the current is limited when the peak value of this board is 0.7V. The pin 4 is a line voltage detecting pin. It detects the input AC Voltage, and when the 264V voltage becomes lower to about 80V, the amplifying ratio of the 4th pin is higher, and the duty cycle of the pin 12 of FPC is higher, the current to the PFC is higher.
  • Page 16 switch into LVDS signal to send it to PANEL for processing. 3、flow of main video signal process： CVBS composite video signal of TUNER (including TUNER signal) and S-VIDEO signal is output to PW106 of SCALER board via 2069 of IO board. PW106 handles with the input video signal, such as resolution and field switch, OSD overlapping, multi-window handling, to switch into PANEL-required resolution.
  • Page 17 check if the EAR-INT signal is abnormal, which is in order to avoid wasting time on checking amplifier. Regarding the connecting with IO board, it is important that I2C signal connects with MCU （MCU-INT、SCL－MCU、SDA－MCU）. If there is any problem with the connecting, then the key and remote control work out.
  • Page 18 be realized by one video IC. c）Mini MCU module：remote and key signals receiving. The remote and key signal receiving is dependent, but the processing modes in MCU are the same. If the remote control and key both work out, then judge if the power supply and peripheral circuit of MCU is normal.
