You can use various methods to stop the Sharp Aquos power light from flashing. Kindly try each until you see no power light flashing on your device.

Let us have a look at how you can do this below:

  1. Turn off the TV.

  3. Allow the TV to cool for around five minutes.

If the power outlet you are using has less voltage, your TV power light will blink without turning it on.

The less voltage may happen after a power outage, so that when the electricity comes back it has less power. The solution is to wait until the electricity regains the required power.

If not, try using a different power outlet since the one you are using could be having voltage issues.

Also, if your power outlet has a power strip or power surge, you can remove it then connect the power cord directly to the socket. The strip may be having electric issues causing the TV to blink the power light.

If after trying the above trick your Sharp Aquos still blinks, let us move on to the next method.
