Haier LE55Q6500U Service Manual

The response time of the Haier LE55Q6500U TV is 6.5 milliseconds (Gray to Gray).

The 'POWER FOR REMOTE' signal in the keypad and remote connector (J2) is used to provide power to the remote control.

First, check the CN1 (5VSB) connection. If it's fine, check if CN1ON/OFF is high. If it is, check CN1 (5V 12V). If that's fine, check UL1 (3.3Vsb). If UL1 is fine, check UD6/UD2 (1.15V) and UD1 (1.5V). If any of these components are faulty, you may need to change the Power Board, UL1, or UD6/UD2 and UD1.

If the LED is on, check Y1 (24MHz). If Y1 is faulty, change Y1. If Y1 is fine, change the mainchip U1. If the issue persists, you may need to change the Mainboard.

The P-MOS FOR LVDS_POWER CONTROL (4459(UM1)) is used for controlling the power supply to the LVDS (Low-Voltage Differential Signaling) interface, which is crucial for transmitting high-speed data signals.

To change the resolution settings, you need to access the PC preset mode and select the desired resolution from the available options. The vertical frequency (V.Freq.) and horizontal frequency (H.Freq.) will adjust accordingly.
