Haier 32D2000 Service Manual

The Main Menu for measurements and adjustments includes General Setting, Picture, Sound, and Debug options as detailed in sections 8-2-1 to 8-2-5 of the manual.

It is important to unplug the AC power cord before removing or reinstalling any component to ensure safety and prevent any potential electrical hazards. This precaution is necessary to avoid any risks associated with electrical connections and to protect the receiver from damage.

High voltage in the Haier 32D2000 should only be tested using an appropriate high voltage meter or other voltage measuring device equipped with a suitable high voltage probe. Never test high voltage by 'drawing an arc' as this can be dangerous and potentially harmful.

The back panel of the Haier 32D2000 features various inputs and outputs, including: Earphone output, Line output, Coax output, AV output, YPbPr input, HDMI1 input, HDMI2 (MHL) input, HDMI3 input, VGA input, PC Audio input, RF input, and USB input.

The Haier 32D2000 has three HDMI ports. They are designated as HDMI1, HDMI2 (MHL), and HDMI3.

The 'BL-ON' component is associated with the backlight control in the circuit diagram. It is connected to the 19V/24V power supply and the PWM/ADJ signal, which suggests it plays a role in regulating the backlight intensity or operation.

The Haier 32D2000 uses various types of resistors and capacitors, including 0ohm, 5R1ohm, 68ohm, 75ohm, 33ohm, 10Kohm, 12Kohm, 100ohm, 4K7ohm, 1uF, 0.047uF, 0.1uF, 33pF, 100pF, and 0.1uF-0402-Y5V-+80%-20%-16V.

The Panel Setting menu allows you to choose the LVDS Bit Mode, select the LVDS MAP, choose between ODD or Even for LVDS, adjust the backlight value, and reset the panel setting date.

First, verify if the power has a 5Vstb output. If not, change the power supply. If it does, check if CN4 Pin3/4 has a 5V input. If not, change the power board. If it does, check if CN2 Pin1 has a 12V input. If not, change the power board. If it does, verify if the DC/DC converters have the right output. If not, change the corresponding DC/DC converter. If all checks are correct, change the software. If problems persist, change the mainboard.

To troubleshoot the power board, first verify if CN4 Pin3/4 has a 5V input. If not, change the power board. If it does, check if CN2 Pin1 has a 12V input. If not, change the power board.
