The Haier HL22T has a total of 181 preset channels.

The total power input for the Haier HL22T is less than or equal to 60W.

For added protection during a lightning storm or when the product is left unattended for long periods, unplug it from the wall outlet and disconnect the antenna or cable system. This will prevent damage to the product due to lightning and power line surges.

If the antenna needs to be split for two TVs, install a '2Way Signal Splitter' in the connections.

To adjust the PC sound when using a sound card, make sure to turn on both your PC and TV. Then, use the INPUT button on the remote control to select VGA or HDMI source. Adjust the PC sound as required.

The show lamp (Location No. 1) is a component within the front frame subassembly. It likely serves as an indicator light for various functions or statuses of the Haier HL22T.

The manual does not provide specific details about the functions of AIN0_L and AIN0_R. However, they are listed among other input pins, suggesting they might be related to audio or signal inputs.

First, verify that the television is properly plugged in and receiving power. Then, check if correct signals are input by pressing the INPUT button to change signal input to TV input. If the problem persists, restart the television as power supply might be interrupted.

The backlight may turn off or lose action due to a damaged B/L wire, an open B/L wire, or a shutdown of the B/L unit. This can be caused by mechanical noise from the backlight unit, poor connection between the wire and electrode, or short circuits.
