Haier HLC24XLP Service Manual

To use the remote control, refer to section 2.1 of the manual titled 'The Use of Remote Control' on page 6.

To troubleshoot if the Haier HLC24XLP is not starting, follow these steps: 1. Check the power board. 2. If the power board output is 19V, check the key board. 3. If the key board is under control, check the IR board. 4. If the IR receiver is normal, check the main board. 5. If none of these components are faulty, replace the power board.

If your Haier HLC24XLP TV has no display, first check if the TV is under control and power on/off by using the remote control and the power key. If it is, check if the backlight is 'On'. If the backlight is not 'On', check the LVDS cable and reinsert or replace it if necessary. If the LVDS cable is fine, check if the Panel Vcc is 5V and if the B/L signal is available. If these are fine, replace the main board. If the power board output is not 19V, replace the power board. If none of these steps work, replace the panel.

If your Haier HLC24XLP TV has a white LED display but no picture, first check if the TV is under control and power on/off by using the remote control and the power key. If it is, check if the backlight is 'On'. If the backlight is not 'On', check the LVDS cable and reinsert or replace it if necessary. If the LVDS cable is fine, check if the Panel Vcc is 5V and if the B/L signal is available. If these are fine, replace the main board. If the power board output is not 19V, replace the power board. If none of these steps work, replace the panel.

To troubleshoot the OSD, follow these steps: 1. Check if the keyboard is connected properly and reconnect it if necessary. 2. Verify if the buttons are functioning correctly. 3. If the buttons are not working, replace the button function. 4. If the keyboard is not functioning, enter the factory mode to do a 'Reset'. 5. If the issue persists, replace the main board or the keyboard.

To perform a firmware upgrade, first ensure the TV is powered on by plugging it in. Then, plug the prepared USB memory stick into the USB port on the side I/O port of the TV. The TV will automatically detect the firmware file and begin the upgrade process.

Do not turn off the TV during the upgrade process. If you do, it may interrupt the upgrade and cause issues with the TV's functionality.

To connect a DVD player to the Haier HLC24XLP using the AV/YPbPr inputs, you need to use the appropriate cables that match the AV/YPbPr ports. Connect the Y, Pb, and Pr outputs from the DVD player to the corresponding Y PbPr_Y, Y PbPr_Pb, and Y PbPr_Pr inputs on the Haier HLC24XLP. Additionally, connect the audio outputs from the DVD player to the AV_Audio_L and AV_Audio_R inputs on the Haier HLC24XLP.

The SIO I/F section in the Haier HLC24XLP manual appears to be related to the Serial Input/Output Interface, which is crucial for communication and data transfer between different components of the device. It includes various pins and resistors that facilitate this communication.

The SIO I/F section lists several components including resistors (e.g., R402, R403, R404), capacitors (e.g., C402), and various pins (e.g., E16, E14, E18) that are essential for the proper functioning of the Serial Input/Output Interface. These components are likely used for signal conditioning, voltage regulation, and data transmission.
