Applicable to Skyworth TV remote control YK-6800J/H 32/40/65H5 55H6 5H5M 58H8M
No matter what reason the remote control is broken, don't rush to repair it if it is broken. It can be repaired at home.
Guide: The remote control is very useful at home, but it will fail after a long time. In fact, you can understand the principle and problems of the remote control. You should know.
Everyone is familiar with the remote control. The TV and air conditioner in the home are controlled by the remote control, which is quite convenient. However, the remote control that has been used for a long time often breaks down or reacts slowly, and many people will spend money to repair it. In fact, we can repair it at home just by understanding the cause and repair method of the remote control. Today, we will talk about the remote control with you.

Operating principle of remote control
Remote control is a wireless transmitter that encodes button information through modern digital coding technology. Light waves are emitted through infrared diodes. The light wave converts the received infrared signal into electrical signal through the infrared receiver of the receiver, and controls the machine through decoding instructions.
Remote control failure reason
TV remote controller is mainly composed of battery, microprocessor chip, crystal oscillator, circuit board, amplification transistor, infrared light emitting diode and keyboard. After understanding the working principle of the remote control, you can judge whether it is damaged through several important parts, and sort out a few situations for you.
1. Battery condition. Because the power required by the remote control is small and the two batteries can be used for a long time, it is easy to ignore the power problem. First remove the battery, wipe the power contact point of the remote control, install two battery replacement positions, and try to replace the new battery.
2. Key keyboard. We may only know that the key can be controlled, but the inside of the key is coated with conductive rubber, which corresponds to the key contact circuit on the circuit board. Each time the button is pressed manually, the two contacts open the circuit and send commands to the machine. However, after a long time of use, the conductive rubber on the keyboard is attached to the dirt. In addition, the conductive rubber is damaged or aged, resulting in failure to power on, which will also lead to remote control failure.
3. Circuit board. There are two kinds of circuit boards for TV remote control, namely copper foil and carbon film. If there is a problem with the circuit board, it will basically fail. Generally speaking, falling to the ground will cause the circuit board to break.

Solution to failure
In fact, the solution is also very simple. By analyzing the causes of the above failures, we can tailor the remedy to the situation.
First, remove the reason why the remote controller has no battery by replacing the battery and wiping the power contact point. Secondly, we can open the remote control, find the black conductive rubber, wipe the dust on the surface, and use 2B rubber and pencil, the main component of which is carbon, to restore the conductivity. If neither of these two methods can be used again, you can only go to the local digital TV business hall or buy online.
Maintenance of remote control
First of all, the distance between the remote control and the receiver should not exceed 10 meters, and the deviation angle should not exceed 25 degrees.
Second, avoid strong light, including sunlight and light, when using the remote control, otherwise the use effect of the remote control will be affected.
Third, when the remote control is not used for a long time, the battery in the box should be taken out to prevent the electrolyte leakage from corroding the components in the box.
