Reasons and what to do if Samsung TV does not turn on
Television is an everyday element of any apartment, allowing its owners to relax after hard days of work. Unfortunately, not all household appliances last forever, and sooner or later the TV fails. In most cases, its repair is possible only in a service center, but there are a number of breakdowns that you can fix yourself. Let's see why a Samsung TV may not turn on and how to fix it at home.
The main causes of failure
A TV is a complex household appliance that fails for many reasons. If we talk about the most common breakdown options, there are:
- the wire that powers the TV is damaged;
- power is off;
- the control panel does not work properly;
- LED backlight issues;
- one of the control panels is damaged.
How to properly diagnose a fault
If the TV shows no signs of life or is not functioning properly, try to diagnose the damage yourself before transporting it for repair. Sometimes the problem is not as bad as it seems, and you will have to pay a lot of money to fix it.
The main thing is to follow the correct sequence of actions and do not forget about safety precautions.
Checking cables and plugs
Before looking for a problem with the TV, check that the outlets or extension cords it is connected to are working. This is often overlooked, assuming the worst case. To check if the outlet is working, just plug in any electronic device and turn it on. If nothing happens, the problem is not with the TV.
Visual inspection for mechanical damage
Manufacturers try to protect fragile parts from damage as much as possible, but no one has yet managed to do this 100%. There is always a risk of breaking the case of the device, damaging the fragile microcircuit with a strong impact. To diagnose such a malfunction, it is enough to carefully examine the TV for cracks or chips.
To note! Before the inspection, it is advisable to disconnect the equipment from the network, in order to avoid accidents.
Checking the LCD monitor
The monitor is one of the most vulnerable points of any television. If cracks or white pixels appear on it, the equipment will need to be taken to a service center for repair. You can try to fix the problem yourself, but for this you need special skills and equipment.
Smell check
In the event of power surges in the network, the "stuffing" of the TV may not withstand and burn out.It's hard to identify the source of the problem visually, especially if you don't know where to look. Smell will come to the rescue.In most cases, problems of this type are accompanied by an unpleasant burning smell, which will not be difficult to smell.
Board inspection
For those who are not afraid to disassemble the TV box on their own, the possibility of visual inspection of the filling of the equipment for damage is open. It is difficult to identify a breakdown in this way, especially if you do not have the appropriate knowledge in this area.
If you decide to take a similar step, pay attention to:
- mechanical damage to contacts, wires and microcircuits;
- traces of temperature effects resulting from overcharging.
Checking the operating system
A malfunction of the operating system is expressed as follows:
- It takes a long time between switching from one channel to another.
- The TV does not respond to commands from the remote control the first time.
It is almost impossible to eliminate such a breakdown on your own, you need to contact a specialist.
Indicator
Samsung, like most other global brands, has developed a special system of signals that express certain types of system malfunctions. The signals are of the following type:
- uniform flashing of the indicator;
- the indicator is constantly on without going out;
- the light is off;
- the color of the indicator changes from green to red.
don't burn
If the TV is connected to the network and the LED is off, the following options are possible:
- the indicator itself is broken;
- problems with the "stuffing" of the TV.
It will not work to repair the fault by yourself, you will need to contact the service center for assistance.
Turn signal
Many owners of Samsung TVs complain that the equipment does not work and the indicator constantly flashes. This is a signal that the power supply has entered a protection mode due to capacitor failure. They must be found and replaced with new ones. It is also recommended to check that the power cord and socket are working properly.
To note! It is recommended to change the capacitors yourself only if you are confident in handling the soldering iron and are not afraid of damaging household appliances. Otherwise, contact a repair shop.
permanently shines
If the indicator is constantly green, but does not respond to commands from the remote, the problem is with the control board. Repairing it yourself, without experience in repairing TVs, will not work, you will only aggravate the situation.
Turns green and turns red
Sometimes the LED will flash continuously, changing color from green to red. Such a signal means a malfunction of the internal elements of the system, which cannot be eliminated on your own.
How to fix yourself
For self-repair, only certain types of breakdowns are available, the elimination of which does not require the intervention of competent specialists. The main thing is to take your time and strictly follow the standard instructions. If you are not confident in your abilities, you should not take risks, it is easier to get the TV repaired.
Standby
The first breakdown, which is easy to fix yourself, is to find the device in sleep mode. In this state, the TV does not respond to external commands.Disabling the mode has a different sequence of actions, which depends on the TV model and its manufacturer. Refer to the instructions supplied with your TV. There, the sleep mode deactivation sequence is described in detail.
Faulty remote control
Often the problem isn't the TV, but the remote control, which companies are less careful about making. Check the console as follows:
- Install new batteries and try changing channels.
- Press different keys and watch the TV indicator. If the remote is working correctly, it should flash in time with the presses.
A broken element can be resoldered, but this is tedious and time-consuming. It is easier to buy a new one for a penny or install the appropriate application on your smartphone. Many modern TV models work well with cell phones.
Broken socket
We de-energize the apartment and replace the damaged outlet with a new one. The main thing is to follow safety rules and correctly plug in the new connector.
Incorrect parameters
Most modern models have a large number of settings, including a child lock function. If you enable it, you will not be able to turn on the TV without a remote control.
Weak signal
Due to bad weather or a problem with the external antenna, the signal may be weak at the TV input. In this case, nothing will be displayed on the screen or only gray ripples will be visible. You should check the antenna performance or wait until the bad weather subsides.
Voltage drops
With strong surges in the network, even a turned off TV can burn out.To avoid such a nuisance, connect expensive equipment not directly, but through special voltage stabilizers.
Breakage of the power button
Symptoms of power button failure:
- After the TV starts, the screen lights up for a split second, then immediately turns off.
- Disconnection is accompanied by a loud click.
- The light goes off.
In this case, the button can be resoldered by yourself, but the wizards do not recommend doing this without the presence of special equipment and knowledge about the device of this TV model.
Unstable Indicator Break
Constant flashing of the LED indicates power problems. You need to check the TV cable and the socket it is connected to.
Grilled backlight
The most expensive and common breakdown of all TV models. To eliminate it, you will need to replace the LCD matrix. It is technically possible to do this at home, but in practice almost no one succeeds. Don't risk an expensive part, contact service.
Cyclic Reload
Occurs when the operating system fails. Update or reinstall the firmware and the problem will go away on its own.
When is it worth contacting a specialist
A diagnosis at the service center is necessary if:
- found problems with the power supply;
- the equipment does not respond to commands from the remote control and the panel, although no fault has been found;
- the replacement of expensive parts is necessary, which requires the captain to have certain knowledge and skills.
