Haier HLTDC19 Service Manual

The functions of the remote controller are described on page 10 of the manual.

To connect your PC to the Haier HLTDC19 TV, use the VGA IN port for video and the PC AUDIO IN port for audio. Connect the VGA cable from your PC's display card to the VGA IN port on the TV, and connect the audio output from your PC to the PC AUDIO IN port on the TV.

To connect an external device to the Haier HLTDC19 TV for both audio and video, use the VIDEO IN and AUDIO IN ports. Connect the video output from the external device to the VIDEO IN port and the audio output to the AUDIO IN port. Alternatively, you can use the S-VIDEO and COMPONENT IN ports for better video quality, depending on the device's output.

The Haier HLTDC19 has 2 built-in speakers with an audio output power of 2*1.5W each.

It is advisable to disconnect the AC power cord from the AC outlet when the product is not used for an extended period of time.

To adjust the picture mode, press the 'P.STD' button on the remote control.

The resistor labeled as 'R204 390ohm-0603-±5%-1/10W' is likely used for current limiting, voltage division, or biasing in the circuit. Its specific function would depend on its placement and the surrounding components in the circuit.

The 5V_RGB and VGA_HS components are part of the circuit design and are likely related to the RGB signal and horizontal sync for the VGA output. However, specific functions are not detailed in the provided content.
