Repair of TV remotes

. We do not notice how important this item is until it breaks. Yes, it's about him - about the remote control. But do not panic: repairing the remotes for the TV - not the most difficult, you can do on their own. In this article, we will analyze all possible causes of its malfunction and step by step, decide how to fix it for a particular problem.

What could be the malfunction?

There are several common causes of problems, in which panic is not needed, and for a new D / U, you should not run either.

Cause 1

The most common is a defect in which the terminals do not contact the power source badly. Since for their production an alloy is used which is not quite suitable for such a device, the terminals easily bend, become less elastic during operation.

To eliminate their springiness, it is possible to make a strip of non-rigid rubber between the terminals and the end of the board, thanks to which the contacts with the battery are securely connected.

Important! To make such a gasket, you can use the usual clerical eraser.

Reason 2

Also common is the deterioration of the contact between the graphite printed circuit board elements and the conductive rubber, which is pressed by the control buttons.

The reason may be falling between fat or a decrease in the quality of rubber, because a couple of years of work from it is the release of an oily substance.

Cause 3

A common problem is the termination of the most current buttons. They can work, but only with great effort. The reason for this is the wear of the conductive coating of the rubber base contacts. There is a physical wear of rubber contacts under the buttons, as a result - the conductivity is lost.

How to repair?

A viscous liquid may appear on the printed circuit board, for which a dry soft cloth is used. To restore the graphite contacts a soft office pencil is used.

Important! Do not use alcohol, cologne or solvent to clean the graphite contacts. Substances with alcohol in the composition lead to the destruction of graphite.

After repairing the board it is necessary to check its operability:

1. We collect the panel into the case.
2. Install the power source, but do not stack the rubber mat with the buttons.
3. From the foil we make a small pointer.
4. Through the holes for the buttons, touch the graphite contacts.

The remote does not respond to pressing the buttons

The situation when nothing happens when you press the buttons on the remote is quite common. That is, there is no switching channels and changing the sound.

Reasons for only two:

• Batteries are discharged;
• The remote control did not fall once.

In the first case, everything is very simple - we change the batteries. Even a child can do it.

After the control panel has fallen onto the floor, there is a breakdown of the connections at the solder points. To check if the device works, it's quite simple:

1. Turn on the camera on your mobile phone.
2. Direct the remote control to the camera and press any button;
3. In case of signal transmission, a luminous thick dot appears on the phone screen.

If it is not required, disassemble the console, inspect the card and perform a full repair.

Important! When disassembling the device, care must be taken so that there are no scratches and chips on the case.

A magnifying glass is used to inspect the card for problems. During repair, you will need to work with a soldering iron.

Important! The most common problems are the detachment of the LED, the contact areas of the batteries or the damage to the crystal.

Determine that the quartz resonator is damaged, it is quite simple: the console is slightly shaken. If there is a rustle, a crack appears in the resonator and its replacement is required.

Some

buttons work when pressed This problem occurs when the oil condensate forms. The repair of the Samsung TV remote control or another model in this case is very simple:

1. The remote control is disassembled.
2. The board is wiped to remove plaque.
3. The contact pad of the keys is being wiped.

Important! When wiping, do not be too zealous, as it may damage the contacts.

Than wipe?

• Sometimes for such purposes use alcohol, but if you do not want to risk, you can replace it with a soap solution.
• If the spring contact is heavily soiled, sandpaper or a stiff sponge is used.

After the drying of all the parts, they are going back. So simply solved the problem, when the remote does not work from the TV.

No response to the most popular buttons of the

From frequent use, some buttons are erased, more precisely - conducting sputtering. With this you can easily handle yourself:

1. The remote opens, the rubber part gets to.
2. On the reverse side of the buttons is glued a thin foil. For this, silicone glue or "Moment" is used.

Important! You can use special kits, which include glue and buttons with spraying.

Clean and my console

We figured out how to repair the remote from the TV with our own hands, but in order for it to last longer, it needs to be looked after:

• Rarely there are remotes packed in a polyethylene bag. That is why the rubber base eventually becomes covered with dust and fatty deposits. Because of this, there is a worsening of the work, and later the destruction of button contacts. All this dirt must be disposed of.

Important! Contacts can be graphite-coated or tin-plated. Accordingly - the color can be black or metallic - copper. Black contacts do not need to be heavily scratched, since if they have copper tracks on them, they will be spoiled.

• With a small amount of dirt, you can confine yourself to local cleaning. To remove dirt, a cotton swab dipped in alcohol is used. Do not use acetone or other aggressive solvents. When washing off the plaque from the rubber base, the actions should be neat to avoid damage to the conductive coating.
• In case of extensive contamination, an old toothbrush and soap solution are used to clean the board and rubber base. After the procedure, the foam is thoroughly washed off, and the board with the substrate is dried.

Little to know how to fix the remote from the TV at home, you need to be able to do the prevention:

• Periodically you need to check the battery compartment. Contacts in it should not be bent or oxidized. In the presence of oxides, they are cleaned to shine using a knife or a screwdriver.
• Also periodically checked places in which the radio components are soldered, especially - battery contacts and infrared diode. Here it is possible to form annular cracks.

As you can see, in the care and repair of the remote control D / U there is nothing complicated. Almost any breakage can be eliminated in a short time with your own hands. If the remote is very old and you do not see the point of repairing it, you can always buy a new universal device.
