Page 3: Safety Precautions
Attention: This service manual is only for service personnel to take reference with. Before servicing please read the following points carefully. Safety precautions 1. Instructions Be sure to switch off the power supply before replacing or welding any components or inserting/plugging in connection wire Anti static measures to be taken (throughout the entire production process!): a) Do not touch here and there by hand at will;... - Page 4 would be unable to work and no way to get it repaired. If the connection wires, connections or components fixed by the thermotropic glue need to disengage when service, please soak the thermotropic glue into the alcohol and then pull them out in case of dagmage.

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). -
