If your Haier HL24XD2 is not turning on, first check if the AC input is connected and the power is turned on. If the power is on, check if the power board is outputting 5V. If not, replace the power board. If the power board is outputting 5V, check the IR board and LED. If the IR board is faulty, replace it. If the issue persists, replace the main board.

To troubleshoot the power issue on your Haier HL24XD2, follow these steps: 1. Ensure the AC input is connected and the power is turned on. 2. Check if the power board is outputting 5V. 3. If the power board is not outputting 5V, replace the power board. 4. If the power board is outputting 5V, check the IR board and LED. 5. If the IR board is faulty, replace it. 6. If the issue persists, replace the main board.

First, check if the TV is under control and power on/off by remote control and power key. If it is, check if the backlight is 'On'. If the backlight is on, check the LVDS cable and ensure the B/L signal is available. If the signal is not available, reinsert or replace the LVDS cable. If the panel Vcc is 5V, replace the main board. If the power board output is not 16V, replace the power board. If none of these steps resolve the issue, you may need to replace the panel or the main board.

To troubleshoot the 'No display' issue, follow these steps: 1. Check if the TV is under control and power on/off by remote control and power key. 2. Check if the backlight is 'On'. 3. Check the LVDS cable and ensure the B/L signal is available. 4. Check if the panel Vcc is 5V. 5. Check if the power board output is 16V. Depending on the results, you may need to reinsert or replace the LVDS cable, replace the main board, replace the power board, or replace the panel.

To enter the factory mode, turn on the TV, press 'Menu', then press the number keys 1, 9, 9, 9, and 'ENTER'. This will take you to the factory mode.
