The job of a repairman for electrical appliances, for the most part, consists in repairing not some complicated equipment, but techniques of "light combat" - remote controls from TVs or radio tape recorders. These devices become unusable much more often than the devices themselves, which are controlled by these consoles. Most of the faults that occur in these remotes can be made by any man if he disassembled this remote. This article will show you what you need to do to fix your TV remote at home.
It is necessary
Remote control, soldering iron, a set of replaceable rubber products
Instructions
Step 1
The remote control is made of hard plastic and the keyboard is made of soft yet durable rubber. Rubber is a good elastic material. But over time, the rubber can wear off. During one viewing of the program, the remote control keyboard can be used from several times to dozens of times. Multiply this value by the number of programs, advertisements, or TV shows, and then multiply by 365 days a year. For a year, you will get a rather big figure. This is why the keyboard wears out so quickly.
Step 2
Inside the body of the remote control, under the channel keys, there are small rubber products that have the shape of a circle with a hole. If you replace these rubber bands, the remote will take on a new life. Also, the problem may lie in the contamination of the contacts to which the keyboard buttons are adjacent or in the rupture of some wires. To solve the problem of "dirty contacts", it is enough to use cotton wool dipped in alcohol or cologne. To solve the problem of "broken wires", it is worth using a heated soldering iron. Just solder any jumper wires that are out of place.
Step 3
To replace the rubber mugs, you need to disassemble the remote control. Dampen all contacts with damp wipes or a cotton swab dipped in alcohol. Glue a new set of rubber mugs in place of old mugs that have become unusable over several years of use. After assembling the remote control in the reverse order, check the functionality of the remote control.
Step 4
In addition to the standard way to check the operation of the remote control, you can use a digital camera. Focus on the remote control signal output window, press any button on the remote control. With the camera, an ultraviolet beam should appear, which is not visible to the human eye.
