  • Check for proper ventilation around your TV. There should be a minimum of six inches of clearance on each side of your TV to prevent overheating.
  • Replace the bulb.
  • Clean the dirt within your TV’s air vents if they are clogged to prevent overheating.

Problem 2: Black Screen

It is possible for your Sharp TV screen to just go black. If you haven’t experienced this before, you will likely be perplexed. The first thing to do is to find out the possible causes of the problem. Some of them include:

  • Backlight issues.
  • Failure in the TV’s power supply board.
  • Loose connections.
  • TV panel problems.
  • Activated sleep timer.

Problem 3: Blinking Light

There are several reasons why your Sharp TV may have a blinking light. The most likely is a software issue. If there is a glitch in the TV’s software, the light could start blinking. How do you solve the problem?

Solution

Your best line of action when your TV develops this issue is to carry out a Power Cycle reset. Take the following steps to carry out this process:

Step 1: Unplug your TV from the socket or any other power source.

Step 2: Leave the TV to rest for a few minutes. During this period, the TV drains itself of any residual power.

Step 3: Plug your TV into the wall directly to avoid a bad power strip.

Step 4: Switch the TV on then check the light.

By now, the problem should have stopped. If it persists, then you should carry out a factory reset of the TV. Doing this deletes all stored data on your TV and returns it to its original manufacturer settings. If you carry out a factory reset and the problem lingers, you are likely having a hardware problem. In this case, you need to contact a professional or replace the TV altogether.
