TV Power Light Comes On – But No Picture Or Sound

Power light on TV is ON but no pic and no sound? The power ON light or standby light on my TV comes ON sometimes blinking but no sound and no picture. My 55″ Samsung TV has a small light on the bottom of the screen. When I press the remote control to turn the TV ON, the light for power ON is illuminated. However, I see no picture and hear no sound. This is the first time this has ever happened. I have tried all reset procedures possible including unplugging the TV for 10 minutes. Is there a reset method for a flat panel TV or could this mean something in the TV is burnt or faulty?

TV Power ON Light Comes On But No Picture Or SoundTV Power ON Light Comes On But No Picture Or Sound

Here is what to check when your TV is turned on, power light is ON, but no picture is seen or sound is heard:
1 – Be sure the component you are using (Xbox, Cable, SAT, ROKU) is turned ON.
2 – Check to be sure all cable and cords are securely connected to the TV inputs and component outputs.
3 – Make sure you are on the correct input as some TV’s will show a black screen if there is nothing connected to that input.
4 – Unplug the input you are trying to use from the TV (such as an HDMI Cable) and plug it back in.
5 – Check for signs of damage on all cords and cables from the TV to all components.
6 – Make sure the TV is not in ENERGY SAVE MODE, press the button on the remote control to go back to normal mode.
7 – Unplug the TV for 10 minutes to see if there was a temporary one time issue with the TV.
8 – Disconnect the TV from power for 2 minutes, then when plugging it back in PRESS AND HOLD THE POWER BUTTON ON THE TV FOR 10 to 20 SECONDS to try and force the TV to reset.
9 – If after checking all these different issues, you may have a Faulty Power Supply Board, A Bad Capacitor on the Power Supply Board, Loose Wire Harness, or Loose Ribbon Connector in the TV itself.
10Most likely when a TV has the power light ON but NO PICTURE and NO SOUND, it is the Power Supply Board that has failed.

TV Power Supply Boards, Why They Fail?

The capacitors on a Power Supply Board may get a surge from a power outage or something else and fail or “pop”. Examine the Power Supply Board and look for popped capacitors or fluid that is leaking from the base of the capacitors or the tops. The capacitors are located on the power supply board in the TV where the power cord plugs into. Also check the Power Supply Board for burnt or any damaged components. REPLACE CAPS IF NEEDED or REPLACE BOARD IF NEEDED.

As a safety note – If you choose to open the TV to find the issue, remember to turn the TV OFF, unplug it, and wait at least 60 minutes to take the TV apart as voltage may still be stored in the TV.

All of the above methods to troubleshoot why your TV has the power light ON but no sound or picture applies to all brands of TV’s including LG, Samsung, Sony, Sharp, Toshiba, Vizio, Insignia, Element, Etc…

NOTE: If this happens with a Vizio TV, usually you will see the green light and a red light in the triangle under the Vizio name on the front.
