How to Fix Sharp TV Blinking Lights (STEPS)


Why do my Sharp TV’s lights keep blinking?

The main reason why a Sharp TV’s lights keep blinking is because there are software bugs, the device isn’t upgraded to the latest software or because your TV’s power plug is overheating.

 

Causes

  • Bugs in the current software.
  • Software not up to date.
  • Mechanical issue (loosely plugged-in power cable)

 

Bugs in your TV’s software (or un-updated software)

When your Sharp TV’s power light is blinking, it is usually a sign that bugs in your TV’s software are preventing your TV from starting up. Alternatively, it could mean that your Firmware (software) isn’t up to date.

 

Software updates usually come in to fix bugs. So, if you haven’t updated your TV’s software to the latest version, the bugs in your current software version might be causing this issue.

 

Mechanical issues (loosely attached power plug)

Sometimes, when your TV’s light is continuously blinking, it is a sign that you should check your power plug. When power plugs are loosely attached to sockets, they may start heating up (or cause your TV to heat up).

 

The blinking lights, therefore, tell you to immediately check (and re-plug) your power cable.

Corrupted file on your device

Files on your device can get corrupt due to several reasons. If it is because of a bug, wait a couple of days (or even a week or two) to see if it goes away automatically.

 

Corrupted files caused by viruses don’t go away on their own. If this happens, call Sharp’s customer support to review your options.

 

Why is my Sharp TV blinking and not turning on?

Your Sharp TV may not be turning on because your TV is not receiving a sufficient (or stable) supply of electricity, because your remote’s batteries have died, or because there is a corrupt file in your device.

 

Causes

  • Insufficient or unstable power supply to the TV.
  • Dead Batteries in the remote.
  • Corrupted file in your device.

 

Here is how you can fix each of these issues:

 

Insufficient or unstable power supply

Your TV can’t function if it doesn’t receive the right amount of electricity. Loose power cables compromise this. To fix the issue, simply unplug your TV’s power cable and re-plug it firmly into a socket.

 

Dead batteries in the TV remote

Your TV’s remote can’t command the TV to turn on if its batteries are drained.

 

Here is what you should do in this case.

  1. First, slide open the battery lid of your remote
  2. Now, take out the batteries of your remote and, with the batteries still out, press the power button of your TV’s remote for 15 seconds (to drain out any energy left within the remote).
  3. Now, place the batteries right back into the remote and see if it’s working.
  4. If it is, Great! If it isn’t, try replacing the batteries of your remote.

 

Corrupted file in the device

Corrupted files stop your TV from turning on because your device is unable to open or read them.In such cases, wait for a couple of days to see if the issue gets resolved on its own. If it doesn’t, call customer support.

Why does my Sharp TV Screen keep flickering on and off?

The reason why your Sharp TV’s screen keeps flickering on and off is either because some of your cables are loose (or damaged), the video you’re trying to play on the screen is corrupt, or some internal hardware component is damaged.

 

Causes

  • Loose or damaged cables (especially the power cable)
  • Corrupted Video playing
  • Internal Hardware component damaged.

 

Loose or damaged cables (especially the power cable)

When the HDMI cables attached to your device are either damaged or loosely attached, they may send interrupted and unstable signals to your TV, causing its screen to flicker. To fix this issue, simply unplug all cables from your device (including the power cable) and then plug them all back in.

 

Corrupted Video Opened

Since your TV can’t read corrupted video files, it won’t know what to display on the screen. Hence, causing it to flicker. When this happens, just restart your TV, and you should be good to go.

 

Damaged Internal Hardware Component

If some electrical component within your TV gets damaged (or begins to deteriorate), i.e., a damaged panel, it won’t be able to display any images/ videos on the screen and will instead flicker.

 

Unfortunately, you can’t and shouldn’t try to repair internal hardware damages on your own. Call a Sharp TV technician- or you will risk voiding your TV’s warranty.
