TV does not respond to remote control

What to do if the TV does not respond to remote control commands?

There are a few possible reasons why the TV does not respond to the remote control. To find out the cause, follow these steps.

The problem occurs while turning on the TV.

  • When you turn on the TV with the on/off button or outlet, or when you exit the standby mode, the indicator light will be on for about 10-15 seconds. This time is necessary for the TV to load the software.
  • If the TV does not respond to the remote control or the buttons on the remote control.
  • Wait until the indicator light turns off.

The remote control has stopped working.

If the remote control sensor (LED light) on the TV does not blink when you press the remote control buttons, do the following.

Make sure there is no nearby interference.

  • Turn off all bright light sources, such as fluorescent lights, overhead lights or light fixtures that can interfere with the remote control signal.
  • Some electronic devices cause interference, so it is recommended to turn off all devices operating near the TV.

If the TV still does not respond to the remote control, follow these steps to check if the remote control is working.

  • Selectively check some functions of the remote control. If the TV is still not responding, the remote control battery may be low, replace it.
  • Make sure the polarity is correct when you insert the battery (see “Battery Replacement” on page 31). markings in the battery compartment).
  • After replacing the battery, selectively check some functions of the remote control.

If the TV still does not respond, use a cell phone with a camera or a digital camera to check if the remote control.

  • Look at the transmitter through the digital camera (or through the camera on a cell phone).
  • Press any button on the remote control.
  • If you see a red blinking light, it means the remote control is working. The TV may be defective.
  • If TV works fine, problem could be remote control.

When contacting customer service be prepared to provide the model number and item number. The model number and product number can be found on a sticker on the side/back of the unit.

Pairing (linking) the remote control (new Philips TV)

How to pair your remote control with your Philips TV. In order for the remote control to communicate with the TV, they must be paired. After this, you cannot operate another TV with this remote control. When you turn on the TV for the first time, you are prompted to press the OK button on the remote control. You have paired your remote control with the TV. When you turn off the power to the TV, the pairing is maintained. The TV can store pairing information for up to 5 remotes.

For information on how to use the remote control (RC), refer to the technical documentation of the TV from the equipment manufacturer or the interactive user manual on the corporate page. You can enter the TV model number on the website, go to “Manuals and Specifications” and find the “remote control” section.

In working condition, when you press a command on the remote, the button for the selected mode at the top of the remote should blink red. If this does not happen, you need to analyze the behavior of the TV and the remote control.

Standard remote control problems with DEXP TVs when the TV does not turn on or off:

  • LED does not blink.
  • Visible red light flashes several times.
  • Channels do not change or change slowly.
  • Problems with volume control.

To determine which of these conditions is causing the problem, perform the following steps:

  • Open the battery compartment on the back of the remote control and remove both batteries.
  • Press and hold any button on remote control for 20 seconds.
  • Release button and insert batteries properly.
  • If the remote control will respond, then there was a failure in it, which disappeared, when turned on, when there was a discharge reset in the previous step.
  • If remote control doesn’t work and TV can’t disconnect, continue with the investigation.
does, respond, remote, control

Most TV remote controls depend on an infrared signal that is transmitted over a distance, and the TV picks it up. If the signal is blocked, you need to check the area between the user and the TV to see if the infrared radiation is blocked by anything, like furniture, books or DVDs stacked right in front of the TV.

The distance between the remote control and the TV is also important. If the remote control does not work, you need to get close to the TV and check its operation. To do this, hold the remote control about half a meter away from the TV and press the power button. You can read the user manual of the receiver to see how far apart the remote control and the receiver can be. If the device pointed at the center of the TV does not turn it on, point it to each corner of the screen. If there is no progress, proceed to check the batteries. Weak batteries can also affect signal strength.

Repairing remotes

First you need to disassemble the remote. The process will be the same for different devices.

You need to take out the batteries and unscrew the screws, located under the factory stickers. In new models they may not be present, so you must start disassembling immediately.

All remotes consist of two halves, and to disconnect them, you can use two ways:

  • Any suitable object. a knife or a plastic card. is slipped into the connecting seam.
  • They must be gently slipped into the gap, and begin to separate all the halves of the case until you hear a click.

Important! Using a knife can leave scratches on the remote control, so it is better to use a plastic card. It is not necessary to take a credit or bank card, in supermarkets or pharmacies after the purchase, sellers offer bonus plastic cards. When you hear a click, this is the signal that the latch is open. Now let’s look at the most popular user questions about repair.

Replacing the boards and the conductive coating

Rubber is a dielectric, but all the buttons on the remote control have a conductive coating. You can check its condition with a tester.

All contacts wear out over time. In this case the repair kit or foil can be useful. As mentioned before, the repair kit is sold with silicone adhesive and conductive rubbers.

Important! You don’t have to buy foil in a store, you can cut a small piece from a pack of chocolate bars you’ve eaten or from a pack of cigarettes. The foil is glued to the rubber pads and placed in the place of the worn-out contact. This method can not guarantee that the switch will work for a long time.

To restore the keys on the remote control, you may also need an unused membrane keyboard. It includes three films that are glued together.

You need to cut out the contact with an insulator and glue it to the R/C board above the graphite contact. When you press the keys on the switch, the contact will be closed through the contact pad from the keyboard.

Only some buttons do not work

This defect is common among owners of older switches. Modern touch sensitive devices have a different design and therefore the buttons of the device break less often.

After 3 years of remote control usage the rubber wears out and a viscous substance starts to show in the area of buttons on the device. It interferes with the normal contact of the conductive coating.

The cause of the sticky substance may be hidden in the accumulation of dust on the device, dirt, spilled liquid. All these elements remain between the buttons and the contacts of the board.

You must disassemble the remote, clean the places with a buildup of thick mass.

A damp cloth will help in removing the dirt, after which the remote control should be wiped and dried.

Note! It is not recommended to use alcohol wipes as they erase the protective layer of the board.

Faulty TV

In addition to the switch, the TV may also be defective. To check your hunch, you need to:

  • Replace the remote control. If when you change the switch, the TV still does not respond to the signal, it is broken.
  • Use the remote control on another device. In case the technique works properly when changing the remote control, the breakdown should be looked for in the TV-panel.

Important! It is not recommended to repair the TV by yourself as it can only make the problem worse. If the TV is under warranty, you can use the service center. You will not have to pay for such repairs. When the warranty card is expired, call a specialist at home. Despite the fact that his services are paid, the TV repair will be cheaper than buying a new one.

Checking the remote control without a TV panel

This method is only suitable for remote controls that work on infrared radiation. For checking you’ll need a cell phone of any brand and its camera.

Even a digital camera will do, if you don’t have your smartphone handy. Place the switch under the turned on camera of the phone. You have to do it in order to keep the infrared LED at the top visible.

Then just press any button and repeat the action on your smartphone camera. If the switch is working, the infrared signal appears on the screen and is displayed in purple.

This means that the batteries are working and the switch is in good condition. If the batteries are half discharged, the brightness of the signal will decrease.

Signal disappears

The TV stops responding to its remote control. the failure is due to loss of signal. Mainly LG and Philips TV owners encounter this problem. The bottom line is that the indicator shows a reaction to commands, but everything remains unchanged, or there is a response, but only after repeated pressing. The problem is solved in two ways:

  • On the front of the TV, press the Program and Volume keys at the same time.
  • If there is no result, you need to try to install the latest version of the software.

If after the work done LG TV still does not respond to the remote control, and nothing has changed, you need to continue diagnostics.

Batteries

Before making any serious adjustments or repairs to the remote control, you should carefully inspect the front of the remote to make sure it’s using IR and not other technology such as Bluetooth or Wi-Fi. Smart phones and some smart remotes do not use IR technology.

The remote sensor will now respond if the batteries powering the DPU were too weak. If Smart TV didn’t turn on, go to the frequency adjustment procedure.

  • For Samsung and Philips press program and volume buttons at the same time. The signal will automatically resume. If it does not work you need to reflash the device.
  • Some remote controls can be used for alternate control of several devices. The toggle buttons are at the very top. Make sure you select the correct input channel on your TV (input, TV, AV, video and source).
  • Use the mobile utility and set up the electronic remote from your smartphone. Step by step description here.

The batteries

The most common reason for a device to stop working is that the batteries are dead. This is also shown by the statistics of customers’ requests to the points of repair of household appliances. But replacing the power supplies is the easiest thing to do, and not difficult to do. On the back side of the device there is a cover, under which you can find the batteries. There is a special grooved surface on the lid, by pushing on it you can easily move the lid. The movement is in the direction that the arrows point. After opening the compartment remove the old batteries and dispose of them and put the new ones in their place, observing the polarity.

There may be another reason: the batteries themselves are fine, but the contacts in the battery compartment are oxidized or loose. To check their condition, remove the cover as described above. Rock the batteries a little. If they are loose, loose in their socket, they need to be tightened. After removing the batteries use a screwdriver to tighten the contacts, then reinsert the batteries.

Oxidized steel parts do not conduct electricity. Oxidation is caused by dirt, dust, moisture. Use a cotton swab soaked in alcohol or cologne to wipe the contacts. If that is not enough, and the corrosion is not completely removed, remove it with a sharp metal wand. A needle or screwdriver is good.

How to fix the problem

If discharged batteries are the cause of the problem, this is the easiest way. You just need to replace the batteries with new ones.

Same with extraneous interference. You need to eliminate them and everything will work. Use one of following ways to solve the problem.

Repair of the old remote control. If remote control is repairable, you can take it to a service center. There it will be repaired and you can use it again. However, repairing the remote control can be much more expensive than buying a new one.

Buying a new remote control. If you know the model of your TV, you just need to come to a specialized store and name the model. A specialist will find a suitable remote control for you. You can also get a universal remote control which just sync with any TV.

Installing special application on your smartphone. At the moment there are many smartphone apps that can replace the remote control for your TV. This option will help you to replace the remote control until you buy a new one.

Service center. If after all the checks the remote control turned out to be working, then the reason lies in the TV itself. If this happens, the specialists at the service center can help you. You can get the addresses of service centers from the store where you purchased your TV. And if the equipment is still under warranty, maybe the store itself can accept the TV for repair or replace it with a new one.

Check the functionality of the remote control

To check if the remote control is working properly, proceed as follows

Place new batteries in remote, preferably alkaline non-rechargeable batteries.

Check the remote control with a digital camera or camera on your smart device. Infrared light cannot be seen by the human eye, but can be seen when viewing the screen of a switched on camera or Smart device.

Note: The following steps are not possible with iPhone / iPad camera! They have an IR filter.

Point the infrared LED light of the remote control at the camera lens

Press the button on the remote control

A white light should be visible on the screen when a button on the remote control is pressed.

2.3 Does the LED on the TV light up when you press a button on the remote control?

No, the LED does not light up: the remote control (or its batteries) is not working properly. Follow step 4.

Yes. The remote control is working properly; If the TV still does not respond to the remote control, go to step 3.

What to do if the TV does not respond to remote control commands?

There are several possible reasons why the TV does not respond to the remote control. To find out the cause, follow these steps.

The problem occurs when the TV is turned on.

  • When you turn on the TV using the on/off button or plug the cord into a power outlet, and when you exit standby mode, the indicator light will be on for about 20-25 seconds. This time is necessary for the TV to load the software.
  • While the screen saver (blue screen with Philips logo) is displayed, the TV does not respond to the remote control or the buttons on the control panel.
  • If the picture appears on the screen for the next 10-15 seconds, the TV will only respond to the 6 function buttons on the remote control (volume /-” buttons, channel switch buttons /-, mute and power button).
  • For the TV to start responding to all buttons, you must wait until the LED stops flashing.

Remote control stops working.

If the remote control sensor (LED lamp) on the TV does not blink when a remote control button is pressed, proceed as follows.

Make sure there is no nearby interference.

  • Turn off all bright light sources, such as fluorescent lights, overhead lights or light fixtures that can interfere with the remote control signal.
  • Some electronic devices cause interference, so we recommend that you switch off all devices operating near the TV.

If the TV still does not respond to the remote control, follow these steps to check that the remote control is working properly.

  • Randomly check some functions of the remote control. If the TV is still not responding, the remote control battery may be empty, replace it.
  • Make sure the battery is inserted with the correct polarity (see the markings on the battery compartment, page 31). Make sure the polarity is correct (see label in battery compartment).
  • After replacing the battery, randomly check some of the remote control functions.

If the TV still does not work, use a camera cell phone or digital camera to check if the remote control is working.

  • Look at the transmitter through a digital camera (or through a camera on a cell phone).
  • Press any button on the remote control.
  • If you see the red blinking light, it means that the remote is working. Your television may be faulty.
  • If the TV works fine, the problem could be the remote control.
