-Samsung TV turning off and on problem

You are watching TV but suddenly the TV turns off and turns on again. This defect is one of the common defects in Samsung LED TV series 5 such as D5000, D5500, D5950. In most cases, this problem is due to the failure of the power board. Board power plays an essential role in turning on the TV, this widely used part supplies voltage to all the different parts of the device, and if it fails, the TV is turned off and will not turn on again.

The serviceman can solve this problem by replacing the TV software, replacing the IC, replacing the parts related to the memory part of the TV and finally replacing the power board completely.

-Samsung TV turns on late

This problem is specific to Samsung LCD TVs and is related to the failure of the device’s power board. This defect is often seen in TVs that are several years old.

Usually, at the beginning of the appearance of the problem, after staying on for a few minutes and the standby light flashing, the TV turns on, and over time it increases and finally, when the power board part of the TV is damaged, it turns off completely.

– Turn off the TV or darken the picture

This failure occurs in Samsung H series LED TVs, model UA48H5590, and to solve this problem, the backlight must be completely replaced. Backlight is a thin screen on the TV panel that consists of a large number of LED lamps. When this part is damaged and the lights start to turn off, the image on the TV will no longer be displayed or a black halo will appear on the image, but the sound will continue to play.

– The image from the upper part becomes dark and light and the image becomes double

This problem occurs in the panel part (screen) and is one of the common problems of the 5 series and 5500, 5550 and 5000 models. To solve this problem, you must first check your cable connections or antenna connections.

Another problem with Samsung TV Series 5 is that the TV turns off during power fluctuations. This issue causes the memory of the TV to be erased and the order of the channels to be messed up. To avoid this problem, it is better to avoid directly connecting the two plugs of the TV to the power outlet and use a protector to control the power fluctuation.

-Samsung TV picture disconnection

With the failure of the Tikan board, which is the last image processing reference before being applied to the TV panel, the TV image is interrupted. Of course, in this mode, there is background light or backlight, which was seen abundantly in Samsung LCD TVs due to the special structure.

– The TV is turned on and the image is cut off after a few seconds

The backlight board and the LEDs inside the panel that make up the backlight are most likely to fail in this problem. Repairing the backlight on your own without the help of an expert not only does not repair your device, but can seriously damage them.

– The TV stays in standby mode and does not turn off

First, check the power board, if this part does not supply enough voltage to other parts of the TV, the TV will turn off and be in standby mode. If the power board is fine, go to the main board and check it.

– The TV has sound but no picture

When the LED TV has sound but no picture, it means that there is a problem with the backlight part of the TV. Backlight failure is very common in LED TVs, as we mentioned, the backlight is a set of LED lamps inside the TV panel. With the failure of one of these lamps, the rest of them are also burnt and damaged, preventing the creation of an image on the screen.

– The TV has a picture but no sound

In the first step, you should go to the TV speakers, today’s TVs are very thin and light. Any defect in these small and compact speakers will make the sound quality very low and reduce the pleasure of watching our favorite movie or series.

If there is a constant problem with the sound on the TV, we should go to the main board. The main board works like a brain and gives all the necessary commands to play the sound and image on the TV.

– The reason why the Samsung TV does not turn on

Fans of the Samsung brand complain about some causes of TV problems; One of the most important complaints is “Samsung TV not turning on”. And the main reason for the TV not turning on is the power board. If it has a very high temperature, it can damage the internal system of the TV.

– The color of the TV is not recognized well

Increase the backlight settings on the TV and go to the Color Temperature option and choose cool colors so you can have a better view of the TV. Also, increase the color settings and finally change the dynamic image to Vivid.
