Use a hair dryer to turn on your LG TV

When your LG TV does not turn on and the red LED flashes, a relatively effective trick is to use a hair dryer to try to turn it back on.

Indeed, very often, the flashing red light means that an internal component is defective and in most cases it is the capacitors (see next part of this article). To help them maintain their role despite the loss of their value, it will then be necessary to warm them up. The hair dryer takes on this role thanks to the hot air it diffuses.

To perform this technique, follow these steps:

• Connect a hair dryer near your LG TV
• Turn it on and direct its blower through the vents on the back of the TV
• Continue for a few minutes while your TV turns back on.
• If this does not happen, try to press the "Power" button on your remote control while keeping the hair dryer on and pointing at the television.

Note: Stop handling if your LG TV does not turn on after 5 minutes to avoid damaging your device.        

Please note that this solution is temporary and has nothing conventional about it. This is a troubleshooting tip. Subsequently, it will be necessary determine the source of the problem which often results from a failure of capacitors. Refer to the next part of our guide to learn more.

Check components and power

The most likely cause of the problem when your LG TV does not turn on and the red light is flashing is that she suffered a internal component failure or that she has a problem in its feeding process.

First, here are the basic checks to perform regarding a power supply malfunction :

• Check that the cables are firmly seated in the ports and that they are not damaged.
• Remove the power strip to avoid voltage problems and the interference it can cause.
• If you have a multimeter, check that the voltage at the wall outlet is high enough.

If all these parameters are correct, it will now be necessary check that the power board and motherboard are working. To do this, you will need to disassemble your LG TV by removing the screws on the back of the latter.

Note before disassembling your LG TV: check that your LG TV is no longer under warranty. If this is the case, do not disassemble your TV as you may not be able to take advantage of the warranty.

After removing the LG TV back cover, check the following:

1/ Visually check that no component on the motherboard and on the power supply board is damaged. They must not be deformed, damaged, melted or burnt. You can also test that the voltage passes on the plates thanks to a multimeter. If no measurement is displayed, the power supply is defective. It will then be necessary to determine the source of the problem and replace the card or the component that has failed. Call in a professional for in-depth expertise.

2/ Check that the capacitors are working. Indeed, in the vast majority of cases, when an LG TV no longer turns on and the red LED flashes, it means that a capacitor has failed. Capacitors are used to fluctuate voltage variations in a circuit. Thus, they store voltage and distribute it with constant intensity when the TV is on standby or slightly higher when the TV is on. In other words, they store the voltage to then distribute it and thus facilitate the start-up of the television. When they are out of order, they no longer deliver enough voltage to start it. A failed capacitor will be swollen on top. You can also measure it through a multimeter. If one or more of them are defective, replace them.

          Be aware of the risk of electric shock and damage to the device.          Switch off the power by unplugging your TV from the wall outlet before handling. If you are not proficient in the manipulations, call in someone close to you or a professional.        

Who to contact when the LG TV does not turn on and the indicator light flashes?

When your LG TV no longer turns on and the red LED continues to flash, this is unfortunately not a good sign. This may be a larger problem with the motherboard or the power supply board.
