Why is there no picture on the color TV of Yimin Ping 'an International Hotel?

It may be caused by incorrect settings.

Solution:

1, check whether the settings are correct. First, check whether the mute button on the remote control is pressed. Secondly, check whether the volume is set to 0. Check the signal source again. Wired signal can check whether the audio system of the remote controller is in DK system. The set-top box or satellite receiver turns the channel button to the left channel and checks whether the audio cable is connected correctly.

Listen to the noise. If the noise is caused by the shift of sound intermediate frequency, the sound can be restored by changing or fine-tuning the sound intermediate frequency. If the noise is small, it is not a sound intermediate frequency fault. Check the sound power amplifier to see if the original performance of the power amplifier block or peripheral is deteriorated. If you don't understand electronics, don't touch them, so as not to cause unnecessary losses. Please have it checked by a professional.
