Haier LE24B8 Service Manual

The total power input for the Haier LE24B8 TV is 35W.

To remove the pedestal, ensure the unit is facing upward and follow the instructions provided in the manual.

To adjust the volume, use the V+ or V- buttons on the front panel. These buttons will increase or decrease the sound level, respectively.

To change the input source, press the SOURCE button on the front panel. This will display the input source menu, allowing you to select the desired input source.

The 'PANEL POWER' component is associated with the power supply for the panel, which is crucial for the display functionality. It is connected to +12V and has specific resistors and capacitors (RD64, RD63, C131, C132) that regulate the power supply to the panel.

The Haier LE24B8 TV offers several rating levels to help you control the content viewed. These include: E (Exempt: Includes news, sports, documents and other information programming), G (General: Considered acceptable for all age groups), PG (Parental Guidance: Intended for a general audience, but may not be suitable for younger children), 14+ (Over 14 Years: Could contain themes where violence is one of the dominant elements of the storyline), 18+ (Adults: Intended for viewers 18 years and older and might contain depictions of violence, graphic language and portrayals of secrecy and nudity).

If your Haier LE24B8 TV has no picture but has sound, you should first check if there is +12V at Pin35 in J1. If the voltage is normal, then check if there is normal voltage at PEC5. If the voltage at PEC5 is not normal, you may need to replace PQ6, PQ14, or PR46. If the issue persists, you might need to replace PU5 or change the panel.

To troubleshoot a main board failure on your Haier LE24B8 TV, follow these steps: Check if there is +12V at Pin35 in J1. If the voltage is normal, check if there is normal voltage at PEC5. If the voltage at PEC5 is not normal, you may need to replace PQ6, PQ14, or PR46. If the issue persists, check if PU6 Pin5 has 3.3V. If not, you might need to replace QD6. If PR46 is working, check if PQ6 and PD14 are functioning correctly. If the voltage at Pin19 is less than 1.25V or the voltage at Pin3 is not 12V, you may need to replace the relevant components.

If there is no sound, no picture, and no LED indication, you should first check the mainboard. If the issue persists, check the following components: U104, UD9, and UD8. If the problem still exists, change PU2 and then check PD3. If you are still having problems, check the mainboard again.

First, verify if the power cord is connected properly. Then, check if the power supply is working normally, including the +5V standby power. Additionally, ensure that the POWER ON/OFF voltage is at high pressure and that the power supply has +12V/+5V output. Finally, check if the Main board, LVDS wire, and Panel are in good condition.
