Any equipment fails over time or malfunctions begin in its operation. This problem also applies to TVs. It may be that when the power button is pressed, the relay clicks, the indicator lights up red, the TV does not turn on. Causes of failure and symptoms can be different. More on all this below.
General problems
The main malfunctions associated with the inability to turn on the TV can be divided into four categories:
- The power indicator is on or blinking, but the device does not respond to the power button.
- The diode on the device is red, but it does not respond to pressing any buttons.
- Indicator off, TV does not turn on.
- When you try to turn on the TV starts to make uncharacteristic sounds and does not turn on.
Despite the fact that most types of such equipment have a different design (namely, LCD, plasma or cathode-beam), due to design differences, they can also differ in size. But the above problems and methods for solving them are suitable for any type of device.
What should I do if the diode blinks and the TV does not turn on?
Most modern models, having found some kind of error, transmit its code with this blinking. Usually you can understand what's the matter by the number of blinks. Information about the error code can be found in the user manual or on the official website of the manufacturer.
If the TV is connected to a PC or laptop, it is possible that the PC has gone into sleep mode. Accordingly, the TV will flash, indicating that there is no signal. To do this, move the mouse or press any key on the keyboard.
What if the LED is on but the TV does not turn on?
There are times when the Toshiba TV does not turn on, but the indicator is on. It is logical to assume that the glow of the lamp on the device means that electricity is supplied to the control unit. If problems with turning on the TV occur when using the remote control, it is worth checking if everything is in order with it. Try to turn on the device using the button on the case.
If the TV turned on, you should make sure that the remote control is working. First you need to find out if the batteries are dead in it, if their contacts are oxidized. Inspect the IR transmitter fordirt or damage. Disassemble the remote control to clean it.
If the remote control is filled with liquid, then it is necessary to return it for repair or replace it. If the device could not be turned on from the button on the case, there may be two reasons for this.
Protection worked
The cause of such malfunctions can be a normal voltage drop or a power outage while the TV was in sleep mode. Also, a similar problem can manifest itself in the form of a short-term inclusion of the TV.
So, the TV does not turn on, the indicator is off. What to do? To exit this emergency mode, it is enough to disconnect the device from the power supply for a while. It is likely that after some time the performance of the device will be restored. If power surges or power outages occur often enough, it is better to purchase a stabilizer or an uninterruptible power supply. As a last resort, you can at least use a surge protector.
Damage to the processor or control unit
The TV may stop turning on due to a short circuit on the board. In the event of such a malfunction, it is categorically not recommended to undertake independent repairs. It is better to contact the service. Unqualified repair attempts may cause irreparable damage to the device.
What should I do if the indicator is off, the TV does not turn on?
This kind of malfunction is caused bylack of power in the electrical network of the device. It may be that even an expensive Samsung TV does not turn on, the indicator does not light up, but the problem may be not only in the device itself. To begin with, it is worth analyzing the possible causes of device malfunctions that you can solve on your own:
- Electricity is not coming to the outlet. The wire, the socket itself may be damaged, or the machine in the shield may simply be turned off. It is worth making sure, if possible, of the integrity of the cable, test the outlet, for example, using another device, or turn the machine on and off several times.
- Extension cord damaged. If you use an extension cord to connect to the power supply, and the Philips TV does not turn on, the indicator does not light when connected through it, you should try connecting the TV directly to establish that the problem is caused by it.
- The power button on the TV is not turned on. This problem can only occur when using the remote control.
- Another mode is on. It is possible that during the previous use of the TV, the AV or HDMI mode was left active on it. The device is going to sleep due to no signal.

In some cases, when you try to turn on the TV, clicks, hum and other noises are heard. The most common causes of these sounds are:
- Protection system. It is triggered by various malfunctions of the internal components of the device. It is she who clicks, disconnecting the electrical circuit of the TV.
