Double image on Samsung TV. Ways to solve the problem

Any double image on the TV indicates the need for diagnostics. This technique will provide an opportunity to identify the exact cause of the failure. The user, in turn, can check the signal level of the TV receiver and the status of the settings. There are problems typical for equipment based on a certain technology. Thanks to these parameters, it is easy to find out the type of malfunction.

LCD LED- often this problem lies in failure of the controller or matrix cable. In more in rare cases, a memory failure may occur, failure motherboard or processor.
Projection- has its own characteristics, in this technique they are responsible for the correct output of the image chip information. Failure of such parts will require their replacement.
Plasma- the occurrence of such breakdowns is extremely rare, but their occurrence will lead to the need to repair the image output unit.
CRT- in this type of equipment such breakdowns can occur due to failure of the power supply or vertical and horizontal scanning systems.

In addition to doubling, the TV screen can be shifted horizontally and vertically. The cause of such problems does not depend on the settings and only calling a wizard will help solve this problem. When connecting some LCD models as a computer monitor, you should pay attention to the screen refresh rate. An indicator of 75 Hz or more will be more comfortable for the eyes and will eliminate image shift.

Troubleshooting and self-repair

A common failure for all systems may be the signal processing board., problems in which lead to an abundance of interference and noise when viewing channels. If there is any doubt, it would be useful to carry out self-diagnosis. This will make sure that a hardware failure has occurred and that the call to the repairman is justified. Usually the image appears double due to poor signal quality and you should definitely check the reception stability to eliminate this oversight.

It may be necessary to change the direction of the antenna to normalize reception. Such failures can occur satellite receiver and should be enabled broadcast channels. Majority LCD TVs have a built-in player, and launch a media file from external storage will help determine the severity of the breakdown. If the double is only on some channels, then the problem is using the reflected signal, you will need to adjust the antenna or buy a more suitable model.

Contacting the workshop and carrying out repairs

When faced with an equipment breakdown one on one, you often feel the desire to fix the problem yourself. We just take it and hit the TV in the hope of “eliminating” the problems. As a result, only the damaged body comes out, broken screen, or cracks along the impact site. Why test the strength of your expensive mechanism like this? It is clearly not designed for such physical exertion. The design does not provide for intervention from inquisitive beginners. In 90% of cases, they interfere with the structure of diagrams and matrices to no avail, after which they come to the conclusion that such manipulations should be carried out by knowledgeable specialists.

Do not do any harm by repairing it yourself; it is better to contact a qualified workshop for help.

When does the TV picture double?

Although this phenomenon rarely occurs in practice, it, unfortunately, does occur. Most likely the problem is bad reception signals. The first thing you should do is pay attention to the receiving equipment, because when antennas are installed, they often get knocked down due to gusts of wind, fail due to lightning strikes, and so on. If the model is old - CRT TV, the signal processing board may malfunction. Find a working analogue and replace it. In more modern LCD models, there is a similar plasma TVs The problem is when the problem area is the matrix controller. It is this detail that is responsible for split image effect. In most cases, such breakdowns are serious and imply irreversible failure of the entire TV. When problems relate to 3D video playback, and the TV image doubles during any viewing, it is impossible to localize the problem to a specific area. We recommend calling a technician to your home to quickly diagnose the problem.
