Page 3: Safety Precautions
Note: This maintenance manual is intended only for the reference of the maintenance people. Please pay attention to the following points before carrying out the maintenance work. Safety Precautions Please read the “Points for attention for the Maintenance & Repair of PDP” and “Criterion for Identifying the Defects on Screen”... - Page 4 static electricity. During maintenance operation be sure to cover yourself with anti-static bag and before operation make sure to have it sufficiently grounded. 1.11 There are a big number of connection wires distributed around the screen. Please take care not to touch or scuff them during maintenance or removing the screen, because once they are damaged the screen will fail to work and it’s not possible to repair it.

Page 11: Method Of Software Upgrading
Method of software upgrading 1: Software writing and upgrade method with ISP writing-device. Main board upgrade: connect a four-pin wire of the ISP writing-device to Debug port(X806) on the main board; Unit upgrade: connect VGA ports of the ISP writing-device and the main board, enter factory menu and set “ISP Mode”... - Page 12 Fig4 selected items Press “Run” in fig4 to begin writing and there are two steps: Erase and Program. If the process of writing succeeds, it will display “Pass” near “Run” as shown in fig5. Fig5 Repeat step 2) and 5) to write the program to the other units without exit the ISP interface. 2: Software writing and upgrade method with USB port Make sure the USB device is formatted as FAT32.

Page 13: Working Principle Analysis Of The Unit
Working principle analysis of the unit 1. PAL/SECAM signal flow: Antenna reception PAL/SECAM signal will be send to tuner TDA1616, which contains frequency turning, HF and IF amplifier circuit and is controlled by master control IC MSD109 (comprises CPU) through I2C bus. The analog IF signal via intermediate frequency amplifying, video SAW filter K3953 and audio SAW filter K9656 to input to analog demodulate IC (IF) R2A10406NP, after demodulating and output standard video signal TV-CVBS and sound IF signal (SIF). -

amplifier BH3547F amplifying, then output two ways. One way will be sent to earphone, another way will be sent to digital sound amplifier R2A15112FP amplifying then sent to speaker. 5. HDMI signal flow Three HDMI video signals via switcher PS321 are directly fed to the master control IC MSD109 to digital decode, image scale and OSD superposition, then output LVDS drive level for panel display. -
