Repair of TV remotes

The life of a modern person is inextricably linked with technical achievements and scientific developments, one of which is the television. No modern living space can be imagined without this device, which serves as a source of entertainment and useful information. Depending on the source of receiving the signal, the number of received channels is often in the tens.

Given this situation, manufacturers have developed a special remote control for gear shifting, which greatly facilitates the operation of modern TVs. High intensity of use and non-observance of the rules of operation of this device often lead to breakdowns and technical malfunctions, which can be corrected both independently and with the help of qualified specialists.

Regular use of the TV remote control, as well as non-observance of the rules of operation, leads to the fact that the device breaks down. If the control panel breaks down, stops responding to commands, does not turn on, the buttons are poorly pressed or do not work, and also do not switch, you must immediately start troubleshooting, which are often not global, but local. Among the most common reasons for the breakdown of the control panel, experts identify the following:

• low battery level;
• frequent falls;
• mechanical wear of the contact pads on the board;
• internal and external contamination of the console;
• lack of response to a TV signal.

Before the advent of mobile phones, ordinary radio receivers, which were tuned to the required range, served as assistants in this work. Modern experts recommend using mobile devices or multimeters for diagnostics. To carry out diagnostic work, you must have a phone with a built-in camera module, and also perform the following sequence of actions:

• enabling camera mode;
• pressing any buttons on the remote while simultaneously directing it to the phone.

A symptom of a remote control board malfunction is the absence of a colored dot on the phone display. If the dot is present, then the cause of the breakdown is in the keyboard, which greatly facilitates the repair process. Using a household tester and multimeter, you can check the presence of a charge in the batteries, as well as the level of voltage supply to the board. Despite the multifunctionality of the device, it is necessary to have a basic set of knowledge and experience to work with it. The main stages of the work:

• setting the required voltage mode;
• making contact between the probes and the battery, which will determine the operating voltage.

In order to independently eliminate all technical malfunctions of the remote control, experts recommend preparing the following necessary tools in advance:

• screwdriwer set;
• plastic plate;
• stationery knife.

The screwdriver set should include both cross and flat tools. Experts recommend purchasing Phillips screwdrivers not separately, but with special kits designed for repairing mobile phones. You will need these tools to remove the screws, the mounting plate, and to rebuild the pads. Flat screwdrivers can be used to remove screws as well as to open the latches.

A thin piece of plastic will help to gradually increase the gap between the halves of the remote control without damaging the fixing elements. The plastic card can be replaced with a guitar pick or a small piece of plastic from children's toys. Even with all the necessary tools, experts recommend using them as carefully as possible., since the design of the remote control is very fragile, and all fixing elements can be damaged even with minimal excessive pressure.

Despite the model variety of TVs, the design of the remote control for all manufacturers remains practically unchanged, therefore, do-it-yourself repairs at home will not cause difficulties even for beginners. In order to disassemble, repair, reanimate or restore the operation of the device if the device responds poorly to commands yourself, it is necessary to prepare the necessary set of tools in advance and open the device as carefully as possible for repair.

One of the most common causes of remote control failure is careless handling of it, as well as its frequent falls even on a soft surface... If, after contact with the floor, the remote control stops working, you must immediately check the integrity of the connections of the contacts with the board. A modern mobile phone can be used to diagnose the presence of a signal. If, after a series of manipulations, the mobile phone does not pick up the signal from the remote control, then it is necessary to solder the board or replace the emitting diodes.

The repair process consists of the following stages:

• extraction by battery;
• opening the latch and detaching the top and bottom of the case;
• studying the state of the board using magnifying tools;
• soldering damaged elements or complete replacement of faulty parts.

Often, watching TV is accompanied by eating delicious food and drinks, which, as a result of careless handling, can get on the TV remote control. Prolonged contact of vapor and liquid with the device provokes the appearance of an oil film on the surface of all parts, which leads to sticking of the control buttons. This defect prevents the device from turning on and brings a lot of discomfort. In order to fix the problem, you need to perform some simple manipulations:

• disassembling the remote control;
• removing dirt from all elements with a cotton swab dipped in an alcohol solution;
• cleaning the springs from corrosive deposits using sandpaper;
• carrying out a complete drying of the device;
• collection of the entire structure.

Cheap models of the device are better protected from contact with alcohol, and dirt can be removed with ordinary soapy water. It is strictly forbidden to wet the electrical board too much, a large volume of water on which can cause the contacts to close. Before reassembling, be sure to wipe off any remaining water with a clean paper towel. To reduce the frequency of contamination, some experienced housewives recommend wrapping the device with a thin transparent plastic wrap, which will not only prevent dirt from getting inside,but it will also help to preserve the aesthetic appearance of the device as long as possible.

Prolonged and intensive use of the remote control often provokes the disappearance of the graphic spray on the buttons, which serves to improve the conduction of electric current.

When a problem appears, experts recommend not rushing to the service center, but trying to solve the problem yourself. Before starting repair work, the following devices must be prepared:

• thin foil on a paper base;
• silicone glue;
• sharp scissors.

The main stages of repair work:

• disassembly of the device;
• dismantling of old rubber elements;
• preparation of pieces of foil of the required size;
• fixing sheets to buttons;
• installation of parts in their original place.

Despite the seeming simplicity of repairing this device, experts recommend that you be as careful as possible when disassembling it. Before starting work, you must carefully study all the design features of the console and carry out the work in the following sequence:

• removing the battery compartment cover;
• dismantling of batteries and fixing screws;
• detaching the upper and lower parts by staggering the fastening elements;
• formation of the required gap for opening with a sharp knife;
• separating the upper and lower parts only after the full disclosure of all fixators;
• removing the board from the slots of the case without damaging the power contacts, radio components and LEDs.

In case of careless disassembly and violation of the integrity of the elements, it is imperative to solder the parts. The following recommendations of specialists can help to reduce the number of breakdowns:

• contact of the remote control only with clean hands;
• the most careful handling;
• timely replacement of batteries;
• carrying out regular cleaning of the surface of the device with an alcohol solution.

The remote control is an integral part of any modern TV, the device greatly facilitates the process of watching your favorite TV programs. The device is prone to frequent breakdowns and malfunctions that can be rectified by yourself. When carrying out repairs, experts recommend observing the maximum level of accuracy, which will help prevent deformation of fragile elements. To reduce the number of breakdowns, experienced housewives advise to minimize contact of the device with food, drinks and dirty hands. - then the device will serve for more than one year without breakdowns.
