This receiver uses electronic technology with the concept of collective line between integrated circuits (I2C bus). The system has control functions and replaces some controls mechanics Instead of adjusting the mechanical controls individually, now many of the functions will be adjusted to through the on-screen menu. (service mode).
The adjustment of this control is important for the due operation of user controls for brightness and image. Do not adjust the variable screen resistor (SCREEN) located on the flyback, until the sub-brightness is adjusted. This control is preset at the factory. It should not be adjusted unless associated circuits have been repaired, the CRT card or when the CRT is replaced.

The DAC8832 is a single, 16-bit, serial-input, voltage-output digital-to-analog converter (DAC) operating from a single 3 V to 5 V power supply. The DAC8832 provides excellent linearity (1 LSB INL), low glitch, low noise, and fast settling (1.0 μS to 1/2 LSB of full-scale output) over the specified temperature range of –40°C to +85°C. The output is unbuffered, which reduces the power consumption and the error introduced by the buffer.
