Make sure that there is no mechanical damage on the screen: cracks, dents, signs of impacts.
If there is no mechanical damage, proceed to the next recommendation.
If there is mechanical damage, contact Samsung service center.
Step 2: Run an image test
A picture test will help you check whether the problem is with the TV or the signal.
If there is a defect in the image test, please contact Samsung service center.
If there is no defect, then the problem is in the signal that goes to the TV. If the image is from an antenna, it most likely has a low resolution - it is better to connect satellite or cable HD TV. If the image is from a PC or set-top box, it may be faulty hdmi cable or video card.
Step 3: Reset your TV
A reset will return the TV to factory condition and clear errors.
Check the image after reset.
Step 4: Update your TV's firmware
If there is new firmware for the TV, install it. If new firmware no, move on to the next recommendation.
Check the image after updating the firmware.
If the defect disappears, then everything is fine with the TV, continue to use it.
If the defect remains, proceed to the next recommendation.
Step 5: Contact a service center
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 rare cases, 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 you have any doubts, it would be useful to conduct an independent 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 you should turn on the broadcast channels. Majority LCD TVs have a built-in player, and launching a media file from an external drive will help determine the severity of the problem. If you see double 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 a breakdown of equipment 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. In other cases, the owners worsen the condition of the equipment, challenging the technicians to eliminate manually caused breakdowns. Do not do any harm by repairing it yourself; it is better to contact a qualified workshop for help.
When does the TV image double?
Although this phenomenon rarely occurs in practice, it, unfortunately, does occur. Most likely, the problem is poor signal reception. 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 problem similar to plasma TVs, 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.
Remember this not a standard situation. A thorough examination of the insides of the TV is required to determine the cause of the split picture. Even at small scales, the eyes quickly get tired, unable to focus on the film, which can ruin the entire movie experience.
You shouldn’t tolerate shortcomings, you need to get rid of them forever!
