Dear,Hello,I'm glad to answer for you,Hisense TV retrieval remote control is gray answer:Hisense TV retrieval remote control function parry stupid display gray is out of order,There are four main reasons for failure:1.

The battery is not having enough power; 2.Problems with infrared sensing; 3.The remote control is damp or the remote control is dusty, resulting in the loss of the head of the remote control; 4.

The touch point of the remote control case is malfunctioning. The above four reasons are the most common in daily life, and they are also repaired by ourselves. Method 1:

Pick off the battery for 3 seconds, then install it with you, press and hold the setting button and don't let go, then press the power off button, then release the remote control, and the light will stay on, and then press the sound plus button again Press the sound plus button continuously When the TV shows the sound picture, release the sound plus button, and then press the setting button. Method 2: Short the two pins of the capacitor (the voltage and capacity are very small, there is no need to use resistors), you can restore the factory settings, the small capacitor inside and the positive and negative poles of the battery box are connected in parallel, so as long as the battery is removed after the garbled code, the positive and negative poles of the battery box are shorted, and the factory settings can be restored.
