How to Fix a Sharp TV Showing a Black Screen


Why Does my Sharp TV have a black Screen?

The reason why your Sharp Tv is showing a black screen is either because there is a corrupt file in your TV, one of your HDMI cables is loose, there was a temporary glitch in the start-up, the screen is damaged, or one of the backlight panels is damaged.

 

Causes

  • Corrupt file
  • Loose HDMI cables
  • Glitch in the start-up
  • Damaged screen.
  • Damaged backlight panel.

 

Corrupt file

Corrupt files can’t be read by your TV’s main board. So, whenever they are opened, your TV stops displaying images/ videos and goes black. If the file is corrupt due to a bug, then it is possible that the issue will resolve itself in a day or two. If it is caused by a virus, however, the issue most likely won’t go away. Call an expert in this case.

 

Loose HDMI cables

Loose HDMI cables send weak/ unstable signals to your device to show different images/ videos on screen. Unstable signals sometimes cause your TV’s screen to black because it confuses it on what to display.

 

Glitch

At times, all there is to a black screen is an annoying little glitch. Just restart your TV when this happens. The black screen should go away.

 

Damaged Screen

If your Screen gets damaged, it won’t be able to show anything on display- causing it to appear black. Call an expert to see if you need to get a repair or a replacement.

 

Damaged Backlight Panel

If the backlight panel is damaged, it won’t be able to display the content that the mainboard has signaled it to display. Instead, a black screen will constantly be on display.

Why does my Sharp TV’s screen go black, but the sound still works?

The reason why your Sharp TV is showing a blank/ black screen while the audio still works is either because your TV’sscreen is damaged, the backlight panel is damaged, it’s just a temporary glitch, or one of your HDMI cables is loose.

 

Potential Causes

  • Loosely attached HDMI Cable
  • Temporary glitch
  • Damaged backlight panel
  • Damaged screen

 

Loose HDMI Cables

A common reason why many people face this issue is because the HDMI cables they’ve connected to their TV is loose. This causes your screen panel to get mixed signals on what to put up on display, causing the screen to just go black. In many instances, this doesn’t affect the audio, hence the black screen, no sound issue.

 

Here is a quick workaround:

  1. Unplug all of your HDMI cables.
  2. Clean their ports of all dust and debris.
  3. Re-plug them firmly and securely back into your TV.

 

Temporary Glitch

Sometimes, all that causes such issues is a simple random glitch. To get rid of it, all you need to do is soft reset your TV.

 

Here are the steps:

  1. Turn off your TV using the remote
  2. Now, unplug your TV’s power cable from the main socket
  3. Next, press down on the TV’s power button for 30 seconds to drain out any remaining electricity from its system. (Ensure that you are pressing down on the TV’s power button, and not the remote’s power button)
  4. Let your TV rest for about 10 to 15 minutes.

 

Damaged backlight panel

When the backlight panel of your screen is damaged, it can’t produce the images that the main board of your TV signals it to produce. This can cause your screen to go black while your audio still plays. Unfortunately, you can’t fix this problem on your own (and you shouldn’t try to if you want to keep the warranty). In such situations, you should always call Sharp’s customer support.

 

Damaged Screen

TVs are fragile devices. Especially their screens – apply too much pressure/ force and it can easily get damaged beyond repair. If your screen is damaged, it won’t be able to display the images it is being signaled to display. The audio will still work. In such cases, you should always call customer support to learn your options.

 

Why is my Sharp TV’s screen flashing black on and off?

The reason why your Sharp TV’s screen is flashing black on and off is either because of a power supply issue or because your TV is stuck in a glitch-caused boot up loop.

 

Causes

  • Power supply issue
  • Boot up loop

 

Power supply issue

Sometimes, when your device is receiving unstable power (most commonly due to loosely connected power cables) it may begin to flicker on and off.

 

Bootup loop

Sometimes, due to glitches, your TV may turn on and off (in a loop) on its own.

 

Soft resetting your TV will fix both of these issues.

 

Just follow these steps:

  1. Turn off your TV using the remote
  2. Now, unplug your TV’s power cable from the main socket
  3. Next, press down on the TV’s power button for 30 seconds to drain out any remaining electricity from its system. (Ensure that you are pressing down on the TV’s power button, and not the remote’s power button)
  4. Let your TV rest for about 10 to 15 minutes.
