What would cause my Samsung TV to not turn on? 

To determine why Samsung TV won’t turn on, you first need to inspect the device for external damage and only then proceed to the diagnosis of the hardware component. Here are a few reasons why this can happen:

  1. Standby mode: When the red light stays on and the display turns off, the device continues to function. To start the TV, press the power button on the front panel of the device or the remote control.
  2. You have broken remote control. First, you need to change the batteries, and also check all the keys. You can always download a special application on your smartphone – TV-remote so that you can switch channels and adjust the volume using the most ordinary phone.
  3. Broken socket. If the indicator does not light up on the control panel, connect the TV to an alternate power source. After that, you can continue to use the device.
  4. It is likely that the emergence of this failure is caused by the activation of AV, HDMI or wireless internet connection. As a result, an image from a mobile device or laptop is displayed on the screen. To resume watching terrestrial TV, simply turn off all devices and check all connected hdmi to vga converters.
  5. Low signal strength. Due to a weak signal, only a black screen is visible on the TV screen, often due to adverse weather conditions: excessive precipitation, thunderstorms, etc. Do not rush to take any action, and it is likely that the broadcast will resume in a few hours.
