Frequently asked questions

To adjust the WB on the Haier LE32B7600/LE43B7600 TV, refer to the WB Adjustment section in the manual, which is located on page 47.

If the display is abnormal, first check the source. If the issue persists, reset the source. If the problem still isn't resolved, enter factory mode and perform 'EEPROM initial' and 'Reset'. If the display is still abnormal, check the main board and replace it if necessary. If the issue is with the LVDS cable, check and replace it. If the panel is the problem, check and replace the panel.

First, check if the remote control battery is properly placed and has power. If the battery is fine, try using another remote control. If that doesn't work, check if the IR board is abnormal. If the IR board is fine, you may need to replace the main board.

The backlight on/off function involves several components, including resistors R701, R722, R707, and R726, as well as transistors Q705 and Q706. These components work together to control the backlight based on the input signals.

To navigate through the menu options, use the 'MENU' button and the directional keys (SW06, SW07, KEY 1, KEY 2) to select and adjust settings.
