To turn on the TV, press the POWER button on the front panel.

To change the input source, press the INPUT button on the front panel.

The panel settings you can adjust include LVDS Bit Mode, LVDS MAP, LVDS ODD/Even, Backlight, 6MX0 LVDS Map, 6MX0 Channel, 6MX0 Mirror, 6MX0 Demo, and 6MX0 Update. You can also reset the panel setting date if needed.

First, verify if the television is properly plugged in and receiving power. Check if the electricity supply is available. If everything is connected correctly, try restarting the television by disconnecting it from the power supply for 10 seconds and then reconnecting it.

To troubleshoot a blank screen, verify if the correct signals are being input. Press the SOURCE button to change the signal input to TV input. If the problem persists, restart the television by disconnecting it from the power supply for 10 seconds and then reconnecting it.

The TPA3110D2PWPR (UA1) is the Audio Amplifier in the Haier 32D3005. It is responsible for amplifying the audio signals to drive the speakers.

If the speakers are not broken, check if the main board has the right input according to the source you are connecting (TV/COMPONENT/AV/VGA/HDMI etc.). Then, check the corresponding audio input circuit you are connecting to. If the issue persists, verify if UA1 has the right output and power. If UA1 is functioning correctly, check CN17 input. If all else fails, you may need to change the mainboard.

If your TV is showing black and white for some channels, first verify if the same problem exists in other channels. If the issue persists, check the picture and sound system of the affected channel. If the problem is still not resolved, change the channel to the correct sound system (PAL-BG SECAM/L) and refer to the relative instructions in the manual for color adjustment. If you still have problems, consider updating the software and rebooting the TV, or changing the mainboard.

A vertical color line or gray line on the screen can be caused by a panel failure, ACF bonding short, or TCP lead cracking.

The backlight shutdown issue could be due to a short between the lamp housing and the wire, which causes the unit to consume too much power. It could also be due to a mechanical noise issue in the backlight unit.
