Haier HL37XLE2 Service Manual

To access the on-screen menu, press the MENU button on the front panel of the TV.

If the remote control is not working, ensure that nothing is blocking the remote sensor on the front panel of the TV. The sensor receives IR signals from the remote control, and any obstruction may interfere with the signal.

The VCC5V_STB and VCC12V_IN are power supply components in the Haier HL37XLE2. They provide the necessary voltage levels for the operation of various electrical parts within the device.

If the color on your Haier HL37XLE2 TV is not displaying correctly, you can use the Auto Color function to adjust it automatically. This function is available for VGA and Component models.

To reset your Haier HL37XLE2 to its factory default settings, you can use the 'Reset all settings to default' function. This will restore the model to its original factory settings.

A horizontal gray line on the screen of the Haier HL37XLE2 can be caused by a failure in the TCP (Tape Carrier Package) or a misalignment between the TCP and the LCD panel.

A vertical color line that is either light or dark on the Haier HL37XLE2 screen can be due to a failure in the Vertical Line/Dim (V L/D) component. This issue might require professional service to address the underlying cause, such as a panel failure or ACF bonding short.

The backlight brightness may be darker than normal due to a damaged B/L wire or a short between the lamp housing and the wire, which can cause excessive power consumption.

If the backlight shuts down intermittently, it could be due to a damaged B/L wire, a short between the wire and the electrode, or mechanical noise from the backlight unit. Check for any visible damage to the wires and ensure proper connections.
