Frequently asked questions

If your TV does not turn on, first check if the AC input is properly connected and the power is turned on. If the power is on, check if the power board is outputting 12V. If not, you may need to replace the power board. If the power board is functioning correctly, check the IR board and LED. If the issue persists, you may need to replace the main board.

If the LED indicator is off, first ensure that the AC input is connected and the power is turned on. If the power is on, check if the power board is outputting 12V. If the power board is functioning correctly, check the IR board and LED. If the issue persists, you may need to replace the IR board or the main board.

If your TV has no display and the LED is red, 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 not 'On', check the LVDS cable and the B/L signal. If the LVDS cable is faulty, reinsert or replace it. If the power board output is not 12V, replace the power board. If the panel Vcc is not 12V, replace the panel. If none of these steps work, replace the main board.

To troubleshoot the backlight issue, first ensure the TV is under control and power on/off by remote control and power key. Then, check if the backlight is 'On'. If it is not, check the LVDS cable and the B/L signal. If the LVDS cable is faulty, reinsert or replace it. If the power board output is not 12V, replace the power board. If the panel Vcc is not 12V, replace the panel. If none of these steps work, replace the main board.

To enable the HDMI ARC function, ensure that the HDMI1-ARC pin is properly connected and grounded. The DC voltage level should be 4V, and the signal voltage p-p should be 500 mV ±100mV. Additionally, a 55 ohm terminal resistor to GND is required for testing.

The resistor labeled 'R9104' has a value of 10 ohms with a 1/8W power rating and a 5% tolerance. Its specific function in the circuit is not detailed in the provided content, but it is likely used for current limiting or voltage division.

The CH+ and CH- buttons on the Haier LE43B7600A are used to change the channels. The CH+ button increases the channel number, while the CH- button decreases it.

The VOL+ and VOL- buttons on the Haier LE43B7600A are used to adjust the volume. The VOL+ button increases the volume, while the VOL- button decreases it.
