Show content articles

Everyone loves to watch TV, but there are times when you just tune in to watch your favorite show, but no. Your favorite TV does not turn on, although the indicator, a red light, is either constantly on or blinking. What to do in such cases, what are the causes of such malfunctions, and how to fix them, can be found in this article.

The TV does not turn on - the indicator is on: causes and solutions

Sometimes a television device malfunctions, just like any other device. Moreover, regardless of its brand, its service life or its type. By type, TVs can be, for example:

kinescope;
liquid crystal;
plasma;
LED TVs.

But, despite the variety of types, the reasons why television devices may not turn on are often the same. Here are a few of them:

problem with the power buttons (if the TV does not turn on, although the red light is blinking, then everything is in order with the voltage supply, if the indicator does not blink, then the reason is either in the button itself, or in the socket, or the contacts have come loose);
if the indicator is constantly on, this may be the case of an incorrectly selected mode;
the plugs are incorrectly connected or they are reversed;
The control panel is faulty, although the indicator is on, but the TV does not respond to manipulations with the remote control (the reason may be a breakdown of the control panel or the batteries are dead).

The indicator flashes randomly

If the indicator light on the TV is on, it means there is electricity in the network. But the device itself does not want to turn on. If you want to turn it on using the remote control, then that may be the problem. To find out you need:

check the condition of the batteries, whether they are inserted correctly, whether the contacts are oxidized);
whether the emitter on the control unit is damaged;
integrity of buttons and PU housing.

If everything is in order with the control panel, but the TV still does not turn on, the indication light, although chaotically, glows, then this serves as a signal that an error has been detected, which can be read about in the instructions for this model of television device.

The indicator light may also blink if the TV functions as a computer monitor. The device also cannot turn on from the control panel if the operating mode is selected incorrectly. When selecting PC and AV modes, the device “falls asleep”. To turn on the TV, you must select TV mode.

It happens that the indicator light does not blink randomly, but in a certain sequence. This is provided by several manufacturers. In this case, their TVs, with indicator signals flashing in a specific sequence, perform a self-diagnosis function. In service departments, experienced specialists using these signals can quickly understand the problem of a TV malfunction.

The indicator is constantly on

If the LED indicator is on, then power is supplied to the control unit. That is, the TV does not turn on, but the indicator light is constantly red. The device may not turn on from the remote control if the remote control is broken or if its batteries are low. To find out, you need to try turning on the TV directly from the control panel on the TV. Sometimes the buttons on the remote get stuck and that's why the TV doesn't respond to it.

Important. If the light is constantly on and the TV does not turn on, this may also indicate a malfunction in the motherboard or a software failure. To find out, you need to carry out diagnostics at a service center.

Problems with TVs of different brands

If the TV does not turn on, then before you panic and call a service center technician, you need to check all the above reasons for simple problems that occur in any type of television device. And currently, as we have already read above, there are three of them:

kinescope;
liquid crystal;
plasma.

Samsung TVs

First, check the power connection. There are several options:

the button itself on the TV panel may not work;
The remote control is faulty or the batteries are dead;
the integrity of the network cable is broken;
the socket is faulty;
problem with the extension cord, if one is used;
there is no light at all inside the network.

For example, such models of these TVs as:

le40r81b;
le32r81b;
le23r51b;
le40s62b;
le20s52bp,

may often not turn on, although the indicator light is on and there is no visible damage. If the indicator does not light, then most often the problem is a simple failure of the socket or lack of light. It’s worth changing the socket or checking with your neighbors for electricity.

If there is light, the mains voltage is present, the LCD TV, for example, does not turn on, although the indicator is on, the remote control is working, then perhaps the fault is in the device itself and it is best to call a specialist service center, especially if the warranty period has not yet expired.

Philips TVs, where to look for the problem

If the TV does not turn on and the indicator light is on, the active mode may not be selected correctly. Modern television devices are equipped with functions that allow you to put the device into “sleep” mode. If this mode was selected, then when you turn on the “TV” mode from the remote control, the TV should respond and turn on.

It is not recommended to solve problems on your own

But if this does not happen, then some parts of the microcircuit, capacitor or power supply may be damaged. It is not recommended to solve problems with this TV on your own. As a last resort, it's best to:

try turning off and turning on the device again, the problem may lie either in the power button, or in a faulty remote control, or in its dead batteries.
A dark TV screen can also occur when the signal from the transmitting device is weak, i.e. The antenna may be incorrectly or poorly connected.

Important. It happens that the TV screen lights up and immediately turns off again. Often this means a malfunction of the device’s microcircuit; only a service center technician can handle this type of malfunction.

If the TV still turns on, but for a very long time, then the reason may lie in one of the television units. Only specialists can understand this problem.

LG TV

When the indicator light flashes on TVs of this series brand:

42pa4510;
ld33b;
42ld650;
42la621v,

its signals indicate device malfunctions. The instructions for the device usually indicate all the blinking codes of the indicator that are responsible for a certain type of breakdown.

Sometimes it happens that the indicator blinks and the TV does not turn on when connecting a television device as a monitor to a computer or player. If the monitor goes into sleep mode, the TV may not turn on, indicating signals from the indicator. This principle of operation is also provided for in modern television devices from other companies, such as, for example:

Samsung le37c530f1w;
Philips;
Rolsen;
Akira;
Toshiba;
Helix;
Supra;
Sharp.

In addition, overheating of the internal parts or body of the TV is also a common problem with modern television devices. Even models of well-known brands, being in good condition, may not turn on if they overheat. If you give the device time to rest, the problem may resolve itself.
