1. Safety Precautions 1. Safety Precautions (1) When moving or laying down a LCD Set, at least two people must work together. Avoid any impact towards the LCD Set. (2) Do not leave a broken LCD Set on for a long time. To prevent any further damages, after checking the condition of the broken Set, make sure to turn the power (AC) off. (3) When opening the BACK COVER, you must turn off power (AC) to prevent any electric shock. (4) When loosening screws, check the position and type of the screw.

Description of video circuit 1) DRX Overview of DRX The Digital Receiver Front-end (DRX) performs the entire multi-standard Quasi Split Sound (QSS) TV IF processing, AGC, video demodulation, and generation of the second sound IF (SIF) requiring only one SAW filter. All control functions and status registers are accessible via I2C bus interface. Therefore, it simplifies the design of high-quality, highly standardized IF stages. For pre-filtering, one 8-MHz channel SAW filter must be used.
