Remote control button did not respond? Teach you some tips to recover "agility"!

At present, many household appliances are controlled by remote control, which is convenient and fast, such as TV, air conditioner, electric fan, etc.

Long-term use of the remote control may cause some key failures. Some people will buy another one or take it to repair, so it will cost a lot of money! Today, I want to share a way to repair the remote control at home.

1. Handle the malfunctioning remote control

When the remote control is abnormal, several keys always fail to work. The other keys are all very good. There is no response when pressing the fault key. This is the aging of the conductive adhesive of the remote control.

Let me teach you a little trick to solve the problem of remote control failure perfectly.

First: Remove the remote control housing

Take out the battery of the remote control, then take out the screws of the remote control, take out the shell of the remote control, and leave the shell, pcb board and conductive adhesive.

Next: clean the remote control pcb board

The cold air of the hair dryer removes the dust on the main board of the remote control. Then use two pcb boards to blow off the plastic and scrub each pcb board to improve the conductivity sensitivity.

Next: Clean the conductive adhesive of the remote control

Wipe the conductive adhesive of the remote control with a cotton ball dipped in alcohol to remove dust and stains.

Then dip your finger in 2B pencil scale graphite, or directly use 2B to smear a pencil on each key until all commonly used keys are smeared.

Then: assemble it back and repair it as new

Assemble the remote control, install the battery, and use it again. You will find that the keys on the remote control have been repaired and there is no abnormality~

The simplest way is to use the alcohol cleaning function to increase the friction of plastic, fuse the conductivity of graphite, and restore the vitality of the remote control!

2. Remote control signal transmission is poor

Many people have a problem. The signal from the remote control is not received. If you sit a little remote, you can't change channels. You must walk to the middle of the TV and stand up. Don't worry! I don't even want to change channels when encountering advertisements

Let me teach you a little trick. Using these gadgets at home can easily help you expand the reception range of remote control signals. No matter where you are, it is easy to change the platform! I believe that every family should have a presbyopic glasses or magnifying glass.

First, remove the presbyopic glasses

Take out the lens of presbyopic glasses, find the place where the small red light of signal transmission in the set-top box flashes, highlight the lens of presbyopic glasses, and take out one of the set-top boxes. (This is also true if your home is TV reception)

Second: fix the lens of presbyopic glasses

Aim the core of presbyopic glasses at the small red light for signal transmission, and then fix the presbyopic glasses on the set-top box with adhesive tape. This is the refraction principle of presbyopia glasses to light. Let all kinds of light focus on the small red light on the set-top box for better signal transmission!

Next: check and adjust the position of presbyopic glasses regularly

At this time, the set-top box can receive signals from all parts of the room. If not, adjust the position of the set-top box so that the small red light of the set-top box faces the center.

3. The remote control battery is dead

The remote control is out of power. I'm worried. Where can I always prepare batteries at home? I have to go out and buy them. In particular, the remote control of the air conditioner has to suffer from the cold wind even if it fails, which is particularly disconsolate! Let me teach you a little skill. Don't worry if the remote control has no battery!

First of all: roll the tinfoil into battery shape

Second: put it into the remote control

The function loss of the battery is unequal. Usually one battery has no power and the other battery has power, so you only need to put the remaining battery and tin foil into the remote control, and you can use the remaining points in the battery!

Next: Restore the remote control

The remote control is very easy to use again. Don't worry about being too hot to sleep
