Converts AC line voltage into the DC voltages required by various circuits. In modern TVs, this is often a Switch Mode Power Supply (SMPS).
Specifically for modern screens, this circuit controls the brightness and operation of the LED strips.
Includes the sound IF amplifier, demodulator, and audio power amplifier to drive the speakers. televizor shema jelektricheskaja
Receives the broadcast signal from the antenna or cable and converts it to an Intermediate Frequency (IF).
In older sets, these circuits control the horizontal and vertical deflection of the electron beam to draw the picture on the tube. Visual Examples of TV Schematics Converts AC line voltage into the DC voltages
