The TV does not respond to the remote control

Problems with TVs can be very varied, but one of the main problems that arise when operating a TV is that the TV does not respond to the control panel. If you study the problem of modern TVs, you don’t have to look for a technician’s number, but can easily fix the problem yourself. If the TV does not turn on, then you need to study the main faults that contribute to this problem. We will talk about them further.

Basic faults

Many people ask the question: “Why doesn’t the TV respond to the remote control?” In this case, the problem is either with the remote control or with the TV. First, look at the TV and remote control, do they show signs of damage? If you are sure that the fault is in the TV, then there may be several reasons:

If there was a thunderstorm in your city that led to voltage surges, then look at the power supply. He is the first to suffer from electrical loads. It may have burned out, then it needs to be replaced. To prevent this from happening, install surge protection. It turns off the device during electrical surges and leaves it in working condition.
If there have been no such incidents in the house, then you need to check the power supply for microcracks in the motherboard. It is quite difficult to solder them, and it is not a fact that an amateur will do it properly; it is better to buy a new one. You can buy a motherboard at a radio equipment store, where the seller will explain to you the intricacies of connecting the board.

The batteries are low

If everything is fine with the TV, then this means that the remote control is not performing its functions. The TV does not respond to the remote control if its batteries are dead or the diode is burned out. The remote control must be carefully inspected. If it has scratches or other damage, this may be why it is not receiving a signal. The TV must receive a signal thanks to infrared radiation from the remote control.

We cannot see the radiation, but they are visible in the photograph. Therefore, take a photo of the remote control when you press the button; if you see in the photo that there is no bright light on the diode, the remote control is not working.

Batteries run out most often, so have several batteries in your kit. After all, they can either shrink or leak. Even if the batteries are new, this can also happen to them.

Very often, stores sell defective batteries that stop working a few days after purchasing them. Be sure to leave a receipt for your purchase, and in this case, ask to exchange the defective ones for new ones.

Causes

First, let's run some diagnostics. It is easy to determine the failure mode. Use the normal elimination method. Check the TV's operation. Can't change the channel even on TV? Most likely, the breakdown is related to it. You won’t be able to fix hardware failures on your own without tools. With this option, it is better to visit a service center. If the LG Smart TV does not respond to the remote control, then the problem is as follows:

the device's batteries are low;
liquid or dust has entered the device;
mechanical wear of the remote control has occurred;
a crack has appeared in the plastic;
The remote control has lost connection with the TV;
there are problems with the infrared port;
there is a problem with the TV itself.

To repair it at home, you need to have the appropriate experience and equipment. Without this, it will be difficult to repair the device. The main symptoms of device failure:

when you press any key, nothing is displayed on the screen;
Some commands are not played at all.

The batteries are low

The failure of the TV remote control is determined using a special tester or voltmeter. Do a little check. Determine the power source. Monitor the readings on a multimeter. The normal level is 1.4 V. Are the readings below normal? Buy batteries at the store. If you don't have tools, just press the keys on the remote control. When the channels do not switch, it means the remote control is broken. When changing batteries, also pay attention to the “plus” and “minus”. Insert the electrodes correctly. Otherwise the remote control will be inactive.

Ingress of water and dirt

When the buttons are pressed tightly, every other time, it means the keys are stuck. Most likely, the remote control is contaminated with various dirt and dust. In addition, problems arise due to liquid getting inside. When water penetrates the device, the contacts close. Due to the sticky layer, some keys sag and become unpressable. To solve the problem yourself, we recommend disassembling the device. Follow the instructions:

Use a small piece of cloth and regular alcohol. Wet it and wipe the contacts.
Also use a cotton swab to clean around the keys.
Also remove dirt from the body.
Do not assemble the remote control right away. Wait for the alcohol to dry completely.

When performing the procedure, proceed as carefully as possible. There is a risk of damaging or breaking some parts.

Mechanical wear

On some keys the top layer is erased. Because of this, the sensitivity of the buttons is lost. To solve the problem you will need:

If you have any questions or complaints, please let us know

Ask a Question

Buy a separate remote control kit. First of all, these are special contacts for self-repair. Place them in the wrong place.
If you don't have such a device at hand, use kitchen foil. Glue it onto the button.
Securely fasten the remote control parts together and check the operation.

Crack

If the remote control is dropped, it may suffer mechanical damage. Most often, the connecting contact breaks or the motherboard becomes deformed. To determine the breakdown, disassemble the device:

remove the cover and batteries;
use a knife or any other tool to pry up the plastic;
after clicking, remove the remaining fasteners;
check the board for cracks and breakages;
Did you see any mechanical damage? Contact the service center.

Lost connection with TV

Check the Bluetooth connection status. Check if the option is enabled on the TV and set-top box. The user may not notice the signal disappearing.

Infrared port malfunction

A certain part of the breakdowns is related to the infrared port of the device. With this option, you will need to contact a specialist. It will replace the broken part. If you have experience in such work and professional equipment, try to fix the problem yourself. Be careful. The contacts on the remote control are quite weak, there is a risk of damaging the element.

Error Exe 001 on Samsung Smart TV: reasons, how to fix?

The problem is with the TV

Any control panel transmits a signal to the TV. If the TV is broken, the infrared beam will not be received. Check through any remote control. On the Smart model it is possible to program an alternative device. Download a separate application to your mobile phone. Using it, you can change the volume, switch channels, and launch functions.

Mechanical breakdowns

Such breakdowns include a problem with the matrix. The matrix is the main part of the screen on which the image is viewed. The matrix can be broken and then you cannot do without the help of a master. In order not to damage it, you need to keep harmful pets, fidgety children and other possible threats away from it.

It happens that the TV does not respond to the remote control. For example, "Samsung" may not respond to the remote control. The buttons on the remote control may not change channels or perform their functions. The buttons on the TV itself may not switch - in this case, you need to check whether the TV has child protection. These operations are explained in the manual of your TV model.

If one button does not work, it may be worn out or the contact has come loose. Modern technologies allow you to use an alternative to the remote control - telephone applications. Thanks to apps, you can transmit the signal better and save money on the remote control. Malfunction of buttons on the TV and remote control is a problem that is familiar to all TV lovers.

If the buttons are damaged, the TV will not respond to signals. The reason may also be incompletely soldered connections. To obtain contact, you need to remove the body or cover of the button and work with a soldering iron. Such soldering does not require any special skills, and if you practice on a couple of boards, you can restore the signal on the TV.

The TV does not turn off/on using the remote control, what is the reason? TV repair.

Long gone are the days when, in order to change channels, make the sound louder or quieter, you had to get up from your chair or sofa. Today, all this can be done using a remote control. When the TV stops responding to remote control commands, this causes concern; many people think that the TV will need repair. Why did the remote control stop working? There may be several reasons for this. 1. Problem with batteries. If the remote control starts transmitting signals to the TV intermittently and switches off spontaneously at regular intervals, the TV will not need to be repaired. You need to check the batteries, most likely they could run out, or in the worst case, leak. 2. There is no signal frequency match. It often happens that the indicator lights up, but the TV does not want to turn on using the remote control. This problem, as practice shows, happens more often with Sony and LG models. Here you should check the remote control for the signal frequency on another similar model, perhaps with neighbors, friends or relatives. Otherwise, immediately contact a TV repair shop, where experienced TV technicians will quickly find the cause. 3. The signal disappears. Owners of Samsung and Philips TVs may encounter a problem where it is not possible to turn the TV off or on using the remote control, while the indicator reacts, but nothing happens. Or the TV reacts if you press any button repeatedly. In this situation, you can try to solve the problem by simultaneously pressing Program and Volume, which are located on the front panel. When the problem cannot be solved, it is better to contact specialists who will repair any TV model in Kyiv, namely, they will reflash the product system to the latest software version. Then the TV is guaranteed to turn on the first time. 4. Extraneous interference. This problem is extremely rare, but it shouldn’t be ruled out either. You need to make sure that nothing is interfering with the remote control, such as a microwave oven. This situation may arise if the TV was installed incorrectly in the kitchen. 5. The problem lies directly in the TV itself. If you have determined for sure that the remote control is working, but the TV still does not turn off using it, it may be time to have the TV repaired at a service center. In this case, there are only two options, either the photodetector is not functioning correctly, or there is a malfunction in the TV control processor. It is not recommended to fix the problem yourself, since irreparable damage can be caused, and then TV repair may become unprofitable.

Signal loss

This problem is common on older Philips TVs. Some Philips models have weak remote control receivers. Such receivers respond to the infrared beam of the remote control only if it is at a distance of no more than five meters. Beyond five meters, the sensor responds poorly to the signal or does not respond at all.

If you have a similar TV and you are satisfied with the image quality and other parameters, but you have a problem with the receiver, then it is better to contact a specialist. The technician will replace your receiver with a new one, and the TV will be able to respond to the remote control signal even at a distance of twenty and twenty-five meters.

Extraneous interference

If you have a “DNS” TV and it makes noise, or stripes appear on the screen, or the image is simply unclear, the cause may be interference. If stripes appear on the TV, this means that there is a device in the mains power supply whose frequency is more than 50 Hz. Also, vertical and horizontal stripes may appear if an ungrounded signal source and receiver are powered from different phases of the network. TVs like DNS may not see the remote control signal.

If you have an older model, phones, tablets, laptops, and other electronic devices may cause noise to be generated into your TV. Due to electronic devices, sometimes the TV does not receive the infrared signal from the remote control. Electronics have their own radiation, magnetic waves that interfere with the remote control signal. Devices that have a magnet in their mechanism can demagnetize the TV picture tube.

A demagnetized kinescope results in multi-colored spots on the screen. To fix this problem, you need to turn the TV on and off several times, or delve into the settings. If the TV has weak diode sensors, the remote control signal can disrupt any electrical device and cause network outages. In this case, the remote control may work, but the TV will not respond to it. Then you need to replace the sensors and monitor the switched on devices on the network.

TV is faulty

If the screen (matrix) is broken, all the boards and power supply are burned out, then it is better not to repair the TV, but to buy a new one. If you have power surges in your home, to prevent anything from burning out, install protection and sometimes look at the parts of the TV.

Now, in times of technological progress, smart TVs are gaining more and more popularity. Thanks to smart TVs, you can watch your favorite shows and movies via the Internet. The most famous Smart TVs are LG and Samsung. These TVs have built-in modern signal receiving receivers, and stores give them a warranty of at least three years. Smart TVs can be controlled using a phone application.

Of course, even TVs with titanium coating and heavy-duty circuit boards can break. Be careful when choosing a TV and then you will be protected from many problems and malfunctions in the future. Now you know what breakdowns most often occur with a TV.

We repair buttons

There are two options, or buy the same buttons and solder them onto the board, and it is advisable to replace everything, since it is not always possible to find out exactly which of them behave hooliganly due to the high instability of this breakdown.

Or disassemble the buttons and put them in order. This is true not always possible and depends on the type of buttons installed. But in my case this was a possible and not difficult action. If you have buttons like the ones in the photo below, then you can do it easily.

This button is not difficult to disassemble, you just need to pick up the metal part with something sharp and “unfasten” it from the plastic part, while making sure that the insides of the button do not fall out and get lost. The disassembled button looks like this.

But in order to restore them, it is not even necessary to remove them from the scarf. Let's look below.

We take everything apart and clean it. To do this, we use cotton swabs and alcohol. Maybe an eraser. Motorists can use carburetor cleaner or WD40, but do not spray directly from the bottle onto the circuit board; pour the product into a cap and use a cotton swab to clean the contacts. Below you can see that some of the contacts have been cleaned, but some have not yet been cleared. Copper heels can also be rubbed with honey with your fingers. Since we got so deep
