What to do if there is no picture on the TV
First, it should be noted that such a malfunction occurs quite often in a variety of TV brands. Televisions of all brands are equally affected by this: Samsung, LG, Philips, Sony, Panasonic and many others. Therefore, it makes no sense to blame the manufacturer.
There are many reasons for the lack of an image on the screen, and it is unlikely that you will be able to determine it yourself by eye. Most likely, you still have to contact a service center or another repair service. It all depends on the nature of the problem. on this below.
It happens that when you turn on the TV, the first screen saver appears with the manufacturer’s logo (LG, Samsung, Philips, and so on), after which the screen simply goes blank. In doing so, you can switch channels and hear sound. Some users noticed that after a while the image appears, but when you turn it on again, everything repeats and the picture is missing. In this case, try the following tips:
- Check the connection of the receiver cord, as it could disconnect. Make sure the cord is connected securely.
- Also, the problem may be in the cable itself. The wire may be damaged or simply turn out to be of poor quality. It concerns HDMI cables. In some cases, replacing the wire allows you to correct the situation.
- Check the power cable. It must also be securely connected.
- Some users have found a rather original way to solve the problem. to increase the volume to maximum (or close to it). After a few seconds, the image will appear and then you can set an acceptable volume level.
Please note that all the tips above will only help if the screen is working. This is indicated by the screen saver when you turn on the TV. If the screen saver is missing and the screen is constantly dark, this already indicates that some component of the TV responsible for the image has failed.
There are several components whose failure can cause the absence of a picture on the screen. Quite often there is a breakdown of the inverter, which supplies voltage to the backlight. The lamps themselves can also fail, and this, in turn, provokes a breakdown in the power supply. In addition to the above malfunctions, a matrix or system board breakdown is often found. Also, the problem may lie in the loops, converter and decoder. In this case, non-working parts and elements will have to be replaced with new ones.
It is not recommended to carry out repairs yourself, since modern TVs are quite complex devices, and you risk aggravating the situation even more. The best decision would be to turn to professionals. This can be a service center of a manufacturing company or a private office, where repairs will be carried out efficiently and promptly.
One way or another, it is impossible to determine the cause of the failure of your TV without a thorough inspection. In any case, the device must be disassembled and diagnosed for non-working parts and components. This is best done in a workshop with appropriate conditions, however, if you do not like this option, many telemasters provide all these services at home.
Of course, replacing some parts can cost a pretty penny, but it should be noted that the matrices or motherboards themselves fail extremely rarely. Typically, a breakdown occurs as a result of physical damage to the part, for example, when the TV falls or moisture gets in. In general, you can’t do without a telemaster.
