If your Haier 48E2500 LED TV is not turning on, it is recommended to contact an experienced professional technician for service or repair. Attempting to service or repair the product yourself could result in serious injury or death.

The resolution of the Haier 48E2500 TV is 1920 x 1080 pixels.

To prepare the Haier 48E2500 TV for wall mounting, first remove the stand by unscrewing the four MB4 x 22mm screws. Then, secure a UL listed wall mount bracket to the back of the TV using the appropriate screws. Ensure the TV is at least 2.36 inches (60 mm) from the wall to prevent cable interference. Follow the instructions provided with the wall mount bracket for proper installation.

The Haier 48E2500 supports HDMI video/audio, component video (which requires an additional audio connection), composite video (which also requires an additional audio connection), analog audio input, and coaxial digital audio connections.

Check the antenna connection on the back of the TV to ensure it is properly connected.

If the EB202 voltage is below 380V, first check if the UB202 voltage is 15V. If it is not, check the power components (DB201, QB201) for any damage. If any components are damaged, replace them. If the issue persists, check if QB304 is damaged and replace it if necessary.

If your Haier 48E2500 TV has no sound, first check the AMP power. If the AMP power is normal, check the voltage at PIN1 of the AMP chip. If that is normal, check the power supply circuit. If the power supply circuit is fine, check the control circuit. If the control circuit is okay, check the input signal. If the input signal is normal, check the circuit from U1 to the AMP. If that is fine, check the output signal. If the output signal is normal, check the circuit between the output jack and the AMP chip. If all else fails, consider changing the AMP chip.

If your Haier 48E2500 TV can't search for any channels or displays no picture, first check the input RF signal. If the RF signal is normal, check the RF source. If the RF source is fine, check the tuner power. If the tuner power is normal, check if the IIC (Inter-Integrated Circuit) is working. If the IIC is fine, check the power supply circuit. If the power supply circuit is okay, check the IIC circuit. If the IIC circuit is fine, check the IFP/IFN output signal. If the IFP/IFN output signal is normal, check the tuner and peripheral components. If all else fails, check the circuit from the tuner to U1 (MSD3393).
