• Constant, daily moving of the TV leads to internal damage. Microcracks appear, the cables can disconnect. So it’s important to keep your device in one place, and not constantly moving it around.
• Dust must not be allowed to accumulate on the display, back of the TV. Micro-particles gradually penetrate and adhere to the contacts. As a result, components overheat, contacts are deformed and there are stripes on the screen. Optimal variant of salvation from dust. blowing with a vacuum cleaner, but with all precautions.

Important! Any cleaning, moving, fixing the TV can be carried out only when turned off. Not just turned off on the button, but unplugged. After cleaning and dusting you must not turn the equipment on at once. You have to wait 2-5 minutes.

• If you can get to the matrix, its disassembly can easily damage the loop, increasing the cost of repair.
• The matrix has to be soldered under a microscope using a special set of tools. There is no such thing in the usual “home workshop”.

Important! Never try to disassemble the TV set under warranty. Even if you unscrew two screws before going to the service center, your case could be considered void because of self-repair attempts.

Find the problematic track with unstable contact, carefully and patiently pierce it in several places with a sharp needle and fill the holes with conductive varnish (it can be found at radiomarkets and hardware stores). After the contact is restored and the lacquer is sufficiently dried up, we tape the repair places with a piece of transparent adhesive tape.

Use it if the first method was ineffective. Disconnect the problematic cable with the hot air from the hair dryer. Use acetone to remove the old anisotropic film from the loop. Clean the oxidized contacts with a sharp object like a scalpel.

Apply liquid rosin to the soldering points, precisely install the tail in place and secure it. Using the soldering iron we heat the tail a little to prepare it for soldering and then solder the pins. Make sure that the solder is properly and evenly distributed on the tracks without forming bridges between them.
