If the Samsung TV stopped turning on

Samsung TV receiver malfunctions can be many, and it is not always necessary to have a qualified wizard help to eliminate them. For example, if the Samsung TV does not turn on, then repairing it yourself in some cases is still possible.

Troubleshooting algorithm

To search for breakdowns in any household appliances, there is a certain sequence of problems search. No exception is the repair of Samsung TVs, for which the search for possible damage starts from the outlet and continues in the power supply.Next, the switching board and the processor module, the sweep and synchronization module, etc. are examined. The study may end up in the control unit, the search for a malfunction in the stabilizer or the discovery of a failed transistor in the horizontal scanning module. Find it all without opening the television set - It is impossible, and the usual owner of the device will not be able to eliminate such a problem.

If the TV is just out of the store, then the probability that it is defective is extremely small. The reason may be your carelessness, and you did something wrong. It is recommended to read carefully instructions for the device. But if he was already at work and suddenly stopped responding when trying to turn on, then searching for the cause of the failure on certain grounds will help to decide whether to contact the service or you can handle it yourself.

When the help of the master is not required

Very often, the owners of television receivers panic and begin to call the master at the slightest problems with his unit. But if you calm down and take a sober look at the situation, then there may be no damage to the equipment. Required to check the behavior of the TV receiver for some symptoms.

Check mode

It is required to check which mode the TV is in.For example, standby mode - this is the standby mode of the TV set, and you can find out about its on state by looking at whether the red light on the unit panel is on. It should be remembered that it is not recommended to leave the television receiver for a long period of time in such a mode, since with the seemingly disconnected unit all the power supply circuits remain energized. If the power supply happens power surgethen all the primary circuits will burn out, after which the receiver will refuse to turn on. Therefore, the unit should be turned off with the button on its panel to reduce the risk of electronic burnout.

Non-working remote control

In the case where you are seeing the indication, but telly does not respond to commands from the remote control, then you can try to turn on the device, using control panellocated on it. If you succeed, the remote is faulty. Although, in principle, it cannot break, except that a resonator made of quartz, which will have to be replaced, may break from a fall. Most often, in the remote control batteries run down. In any case, it is worth disassemble the console and try troubleshoot the remote control with their own hands.

No standby indication

In a situation where there is no indication, and when you press the button, nothing happens, you do not hear clicks and do not notice the blinking of the LED, you can assume that defective outlet. Of course, you can try to connect the device to a different power source, but if this does not help, then without having special knowledge and qualifications, you will not be able to repair the TV set with your own hands. Even the replacement of a conventional fuse will cause you difficulties, since they are not so easy to find in modern TV sets. Therefore - the call of the master will be the right decision.

A single flashing light is noticed.

If a single blinking of the indicator was noticed, after which it continues to light up, or its color has changed, it may mean that the device is in operation mode: either AV or PC connection mode. Therefore, it will be necessary to transfer the unit TV reception mode. In addition, the TV may be blocked from unauthorized use (for example, by children) - in this case, unlock using the instructions to the technique.

Please note: if an antenna is not connected to the television receiver, the television signal is very weak or it is absent at all,then the telly after noise reduction can enter monitor mode. That is, you will see a black screen without sound.

When telemaster assistance is required

Everything that a non-TV technician can do is limited to checking elements outside the device. In other cases, it is not recommended to open the device with your own hands, and you cannot do without a master.

The device did not turn on from the panel

If you turn on the TV from the control panel did not work, then you need to observe the behavior of the standby indicator (normally lit evenly, more often - red). If it turns off when you try to press a button, then the problem should be searched deeper in the device, as this indicates internal lockout (not to be confused with the child lock mode, which is enabled by the user). This happens when one of the modules fails. In some models of telly when the lock is triggered, you can hear the sound of a click. You will not be able to fix such damage yourself. The only sensible solution is to call a specialist.

The indicator turns green and then turns red

This color switch indicates that the CPU has generated a signal to turn on the device, and it has been sent to all modules for its execution. If any module failed, he cannot execute the command. For example, a failure in the power supply does not allow it to go into the desired mode. In this case, the processor, without receiving confirmation from the power supply unit about normal operation, sends a signal to cancel switching on the TV receiver and returns it to sleep.

Such blinking can last for a long time until the main cause of the failure is removed: the inverter has been repaired, the transistor has been replaced (for example, on the s62 chassis), the power supply has been moved, or another of a large number of causes.

The indicator turns green and nothing happens.

When the indicator is green, and TV receiver and does not think to turn onthen this situation can be called ambiguous. Is required check main board with the measurement of the voltage applied to it. There is also a study of launch, backlight, etc. commands.

If the light turns on, indicating a working condition, but there are no signals from the main board, and the device does not respond to the remote control and pressing the buttons on the case, this may indicate software failure. Only flashing and software update will be able to return the normal operation of the motherboard.

LED flashes randomly

This behavior of the indicator indicates that the TV set has failed, and it does not carry any more useful information. Would need complete electronics diagnosticsstarting with the “ringing” of the power supply and ending with the converters located on the motherboard.

The telly turns on for a long time

When turning on the TV receiver takes a lot of time - this indicates that any unit of the unit has failed. For television sets with a kinescope and LCD panels, the factors for occurrence of breakdowns can be very different. To identify a fault, without having the necessary experience and knowledge, is quite difficult. Since the problem block is still starting to work, and only a qualified master can get at the root of the failure, using special equipment to perform the necessary measurements. In some cases, the verification of the apparatus in the service center at the standusing special software.

As can be seen from the above listed possible reasons why the TV stopped turning on, there are not too many options to repair it on our own.This rule applies to the case when the TV turns on and off immediately. And since the unit is a complex electronic device, it requires to itself accuracy in operation and timely service.
