Why Won’t My Sharp TV Turn On (16 Fixes Down Below)


Is your Sharp television not turning on? Numerous consumers have complained in recent years that their Sharp television won’t come on after a power failure, or that their Sharp television won’t switch on but the power light is blinking.

Some users have also reported that the Sharp television will not power on from standby mode. These are some of the circumstances that users encounter when using their Sharp television. We’ll clarify why this is happening and how to remedy it in this article.

There could have been a multitude of causes why your Sharp TV is acting this way, but we’ve compiled a list of likely causes. TV not obtaining sufficient power: Your television may not be acquiring enough electricity to operate, which is why it is not switching on.

It could be a voltage or connection issue, or it could be a broken power connection. The issue can be fixed by replacing the power source in this scenario. Here are reasons why your Sharp TV won’t turn on:

1. Remote is Broken

If you can’t turn on the TV with the remote, it’s possible that the batteries are dead or the buttons are jammed. You can try this by pressing the TV’s button rather. If the TV still switches on when you press this button, the problem is with the remote.

If you have extra batteries and believe that the keys are locked, remove the batteries and click each key at minimum once to reset the controller.

This will enable the remote to reset by draining any remaining power. Before re-inserting the batteries, ensure you push the power switch a few times to dislodge any dirt that has accumulated beneath.

2. Bug in TV

Your Sharp TV might not turn on if there is a fault or a defect in the program of the television. If this is the reason your sharp TV is not working, you will need to get rid of the bug for your TV to come on.

3. Bug with Remote

You might also be having difficulties with turning on Sharp TV if there is already a bug with your remote. This will cause your remote not to function properly. So you will find out that whenever you press your remote, your TV does not come on.

Alternatively, in this case, you can always go to switch on your TV directly from the power button without making use o the remote.

4. Signal Interference

Electromagnetic waves cause interference, which causes problems with TV reception such as pixelation, breakups, and total picture disappearance. While not extremely prevalent, it is one possible cause of poor TV transmission.

The most common cause of poor TV reception is a defective or broken antenna, cabling, and/or connectors.

When watching shows on your TV, you may probably experience audio or visual interruption. This could be anything from seeing a ghost image of another show over your present program to receiving a radio broadcast over the speakers.

5. Overheating

If the airways are unobstructed and the airflow surrounding your TV is decent yet it’s still hot, an exterior source of heat could be the root of the issue. Cover any heating vents around your television. Keep portable heaters away from your TV to lessen their total temperature influence.

When your sharp TV keeps overheating and shuts off, it signifies a severe issue that has to be urgently addressed. Overheating can harm and ruin the tv’s sensitive circuits, thus the Sharp tv turns down as a security precaution. You can easily handle these problems on your own.

Applying a Phillips screwdriver, detach the holding screws that keep the television’s back panel in position. Remove the back panel from the tv and keep aside. Push the projector lamp out from the television by removing the screws that clamp.

Using a soft cloth, a tiny suction tool, and pressurized air, clear as much dust as necessary from the lamp and fan region. Add pressurized air to the back panel’s vents. With the soft cloth, suck up any leftover dust and debris.

Just on right hand side of the television, beside the color wheel, find the 2 cooling fans. Simply replace both fans with new units if you got a blinking notice indicating “CHECK FAN” before the tv switched off.

Take the two screws that hold the black fan casing in place and pull it out. Disconnect the power supply cable for each fan and remove the fans from the enclosures. Link the wire and install the new fans in the black enclosure. Reinstall the enclosure and screw it down.

To clear dust from the projector lamp, use pressurized air. Within the television, place the projector lamp. Replace the screws holding it in position and fasten them with the Phillips screwdriver. Reassemble the tv’s back panel.

Lift the lamp cover door off from the tv by removing the restraining screw. Beneath light cover door, look for the safety circuit. Invert the button until it catches beneath the lamp cover door. After that, replace the lamp cover door.

Remove the tv from close proximity to the walls or other items. The television can overheated owing to insufficient airflow caused by positioning against walls as well as other objects.

If the Samsung DLP television continues to overheated and switch off, contact a qualified service specialist. Internal components that must be maintained by an expert may be the cause of the issue.

6. Power Supply Board Failure

Electrolytic capacitors on the power supply board are the most typical source of failure. 90% of Power Board is made up of loose connections or dry joints. Use it on only AC power directly to the power supply. The power board must be changed if a voltage is absent or changing.

It’s rather simple to diagnose and fix your TV mainboard. A multimeter, a screwdriver, and repair parts are all you’ll require. It’s important to know that your TV may sometimes exhibit issues with regards to a damaged mainboard as a result of a software condition that concerns upgrading.

7. Backlight Broken

Place a flashlight next to it, and verify if you can see the image clearly. The display would be incredibly dark, as if the screen’s intensity had been turned way down.

Backlight problems can be caused by a variety of factors, such as water and drop harm. It could also be the result of a faulty part. You may also notice it while repairing a plasma television burn.

Your television works by allowing images to form on a screen using a filtered light system at the backside of the screen. Regrettably, filtered light will not be reflected on the screen if the backlight is broken or destroyed, and the user will be unable to see visuals.

It is critical to identify the core source of the issue before repairing the damaged backlight. Backlight breakdown is common. To confirm, turn on the screen and place a flashlight as nearer to the screen to see if you can see the image.

Whenever your display’s brightness is set to the lowest setting, the image must be dark. When you’re satisfied with the image, you can change the TV backlight.

8. TV Panel Issue

A loose cable connection, a loose or broken board, or a broken screen are the most common causes of this issue. This is a constant thing with TVs and indicates that the panel is deteriorating.

Intense temperatures, cold, humidity, or precipitation can irreversibly harm the picture of a flat screen television. Hot temperatures or cold can damage the capacity of the pixels to change color effectively, while moisture can burn out circuitry within the TV.

9. Bad Connections

This is an additional cause. Simply reattach all connections at the rear of the TV or box, assuring they are all correctly attached (you would like to eliminate loose wires that could induce signal loss), and if you have a signal booster attached, remove it and put the antenna cable directly into your receiver, recorder, or Television.

10. Sleep timer

This can also be why your Sharp TV is not turning on. Sleep Timer keeps track of sleep cycles and the average time it takes for an user to take a nap (it is 14 minutes). You can use this software to determine when to go to bed, whether you need to awaken at a specific time, or when to awaken if you are currently sleeping.

11. Capacitor Issue

Because AC signals pass through but DC signals are hindered, a capacitor is an electric device that holds an electric charge and is employed in filter circuits. Tv sets have a massive amount of capacitors, which can break down with time.

A damaged capacitor can be visible (leaking brownish fluid, being corroded, or having the connections cut), but it can also be inconspicuous. Instead of being flat or minimally recessed inside like a functioning capacitor, the tip of a damaged capacitor will be gently rounded outwardly in a convex form.

12. Standby Mode

Standby mode is similar to switching your television off but not completely. It enables it to switch on considerably faster than if it were totally deactivated, ensuring that the effects of that key hit are extremely rapid and that you won’t sit out the rest of The X Factor.

Whenever the operator enables the system to engage sleep mode, such as by hitting the power switch, shutting the top, fading out, or choosing Sleep from the power switch in the Windows Start menu, Modern Standby begins. Applications and system software should always be prepared for the switch to low-power functioning when using Modern Standby.

13. Circuit Board

Inspect the circuit board for evidence of degradation such as squashed parts, protrusions, broken wires, fractures, missing or excess solder, burn marks, and blemishes that suggest the board is either defective or in need of substitute and qualified staff

Fortunately, boards can be repaired or remanufactured to bring them back to life. This has one of two effects. Either that the board in issue can be restored to its original mechanism and restored to working order. It can even be reused in a wholly distinct device, thus regenerating it.

Attach the multi-meter probing to the test points on the circuit board to correctly examine it. Ensure you’re holding the plastic part of the probes while performing this procedure. After that, you can examine the voltage or resistivity.

Why is Sharp TV Power Light Blinking

Sharp TV lights are intended to provide information about the unit’s state. The power light or the OPC (Optical Picture Control) light blinking indicates an error message or defect code. It’s difficult to figure out what’s creating the problem.

It could be a tv configuration, a firmware problem, or a mechanical fault that demands service. The approach to bringing your Sharp TV back to its normal state is to try a few popular fixes

The blinking signal may be meaningless to you, but it is significant to a Sharp service expert. Keep an eye on the blinking lights and notice the pattern.

The power light, for instance, may blink significantly faster as the OPC light. The OPC light may flash three times before blinking once. This is a code that tells the expert much about how your system works.

Submit the pattern code to Sharp Product Support at 1-800-237-4277 (1-800-BE-SHARP). They can show you what to do to resolve the issue.

A further probable cause of your Sharp television’s lights blinking is mechanical breakdown. It’s possible that there are power difficulties or that the machine is overheating. You should not attempt to repair a television unless you have prior familiarity with electronics.

Sharp can supply you with a number of qualified experts in your region who can assess the issue and make any necessary repair.

If the set is still under warranty, attempting to repair or replace a damaged item may be considered a violation of the service contract, voiding your protection plan

Here’s how to fix the sharp TV power light blinking problem:

Sharp televisions have many lights that show performance and possible problems. Any operation on the Sharp TV OPC (Optical Picture Control) light that blinks signals a problem. You must investigate to find out the situation and find remedies when the light is consistently blinking.

Hardware faults or the firmware placed on the television can cause issues. You must select the correct potential remedy for the television after examining the condition.

1. Identifying the Issue

Whenever the Sharp TV won’t come on, the power indicators blink, or other problems develop while the Sharp TV OPC light blinks, try to figure out if the matter is hardware or firmware associated. Examine the television for signs of high heat.

Overheating may be caused by a faulty fan or other piece of hardware, leading the television to operate without showing the screen. If the tv is not overheating or producing strange sounds, it could be a firmware or software problem

2. Updates and Reset

Run the entire reset and any upgrades before trying any costly physical maintenance. To commence, perform a power cycle reset. Disconnect the tv and let the power deplete for several minutes. To eliminate out a defective power strip, plug the tv straight into the socket. Restart the TV and examine the indicator.

If the light persists to flash, perform a hard reset to erase any database and reset the tv to its factory default settings. All stored applications and password will be lost, but a new beginning may be the solution. Reconnect the power to do a factory reset. Tap and hold the “input” and “channel down” keys on the remote at the same time.

Press and hold the keys while plugging the TV back in and waiting for it to turn on. To reinstate the factory settings, go to the list and click “Service Mode,” then “Factory Reset.” Examine the OPC light once the tv has closed down and restarted.

3. Hardware Issues

A hardware failure may occur if a full resetting does not resolve the issue. Hardware repairs necessitate specialized parts and the capacity to disassemble the tv to examine and replacement of components. The procedure is developed and should not be attempted by anyone without specialized knowledge and equipment.

Get your tv examined by an expert and receive a repair estimate to see if the hardware is cost – effective of repair. In some circumstances, the best option is to examine the tv for a warranty or to change it.

If your Sharp television is not switching on but the light on it is blinking, you might try forcing it to switch on. You can do so by completing the instructions beneath.

1. On your Sharp TV, simultaneously push the sound down, channel up, and power buttons.

2. A tapping noise will be heard, and your Sharp television will switch on properly.

3. And if this doesn’t work, attempt the procedures described below.

4. Remove the sharp television from the wall socket.

5. Then hit and press the volume up and power buttons simultaneously, then plug in your Sharp television.

6. In 10-20 seconds, your television screen will flash and begin working, after which you should remove the buttons.

7. Switch your configurations to quickstart now.

How to Fix Sharp TV Won’t Turn On

1. Check and Re-plug Cables Correctly

Reposition the power cord in the back of the Sharp television. Unplugging the power connection from the back of the TV is another simple solution to your power issue. Unplug it for around 60 seconds before plugging it back in.

Ensure the connection is tight when you plug it back in, you don’t want this to be slack at all; a firm connection ensures that the TV receives consistent power.

2. Turn on From TV and Not Remote

If it’s a power cord issue, replace the power cord (view on Amazon) and turn on the TV using the power button on the TV, not the remote!. Eventually, the television will awaken

3. Remove Batteries From Sharp Remote

If disconnecting and reconnecting your TV did not resolve the issue, remove the batteries from your remote. Ensure both batteries in the remote are entirely removed. After removing the batteries, press and hold the power button on the control for 30 seconds.

Repeat for a total of half a minute. Replace the batteries in the remote and try to switch on the TV once the entire 30 seconds have passed. It should turn on again. Note that you’ll need to try to replace the batteries during this stage simply to be safe.

4. Force Turn on Sharp TV

If your Sharp TV won’t come on and the front logo blinks rapidly and then slowly, you’ll need to coax it to switch on. To do so, concurrently hit volume down, channel up, and switch on your TV. Ensure you’re using your TV rather than your remote.

The Sharp TV should turn on normally when you detect a “tapping” sound. If this doesn’t succeed, go to “Factory reset Sharp TV without remote” and comply with the regulations below “Buttons on side of your TV.”

5. Use Phone as Remote via Roku App

If you have a Sharp Roku TV, you can also install the Roku app to your mobile. You can use your cellphone as a remote after linking your Television to the application.

6. Use Universal Remote

Another option is to use a universal remote (View on Amazon) that you already have and input the Sharp codes for the control to make it function. You should have addressed your power problems by now, but just in event you have not yet, I’ve included several further measures worth attempting before giving up.

7. Try a Different Power Outlet

Although this is doubtful to be the reason, if you’re still experiencing difficulties, try inserting your Sharp TV into a distinct power source in your apartment. We don’t always notice when an outlet has a short or a burnt fuse.

If you wouldn’t want to haul your TV around, take another little item and connect it into the same socket as your TV. When you see that gadget turn on, you realize the plug is functioning and it is most likely not the problem.

Once more, this is unlikely to be the source of the problem, but it is a necessary diagnostic approach that should be eliminated as soon as possible. Electricity shortages and problems can cause harm to sources of power and outlets in certain instances.

That being stated, if the Sharp TV would not switch on, the power outlet is likely to be faulty. To eliminate out this possibility, try plugging your Sharp TV into a different power outlet. If the TV is working, you should have your power source examined. The best approach is to change the source of power if at all feasible.

8. Firmware Update

Firmware is the program that controls your Sharp TV’S software. Makers will issue updated firmware upgrades as required to increase your unit’s capabilities.

When it’s necessary to refresh the firmware on your TV, consider installing the software according to the directions. You may, for instance, save the firmware to a USB stick on your desktop.

Make absolutely sure the USB device is suitable with the tv by following the manual. If the directions call for FAT formatting of the USB drive, double-check that it is compatible. If you try installing firmware incorrectly, the TV will quit functioning and the lights will flash.

9. Power Cycle

Many people believe that power cycling fixed the problem for them. Comply with the requirements underneath to properly complete a power cycle.

  1. Switch off your Sharp television.
  2. Remove the sharp television from the electrical outlet.
  3. Allow 1 minute to pass.
  4. Then connect the Sharp TV.
  5. Finally, employing your remote, switch it on and see if you can switch on your Sharp television

10. Factory Reset

There are 2 methods to return a Sharp TV to factory settings. Remember that a factory reset will delete all offline files as well as any stored choices. This method, meanwhile, is by far the most efficient at eliminating faults from your television. Follow the instructions below to reset the TV without a remote.

  1. Turn off the television.
  2. On the TV, press and hold the ‘Channel Down’ and ‘Input’ buttons.
  3. While plugging the TV back into the power outlet, continue to hold these two buttons.
  4. When the TV has finished booting up, disengage the keys.
  5. On the ‘Service Mode’ option, choose ‘Factory Reset.’
  6. Pause for the television to turn back on.

When using the control, go to the main menu and select factory reset.

  1. On the remote, click the ‘Menu’ button
  2. Select Settings , System or Support or Setup , then Factory Reset from the drop-down menu.
  3. To begin the reset, click the ‘Ok’ or ‘Play’ key three times, or choose ‘Reset’ and input your TV passcode. ‘1234’ is the default pin.

11. Change the HDML Cable

If your Sharp TV isn’t turning on, be sure to check the following. The sound has been amplified. The television is not set to ‘Mute.’ Your device’s input channel is set to the proper one. If it’s inserted into the ‘HDMI 2’ port, for example, pick ‘HDMI 2’. If none of the above alternatives work, you can perform a hard reset or restore the TV to factory settings.

12. TV Power Board Replacement

Capacitors on the power distribution board are the most typical cause of difficulty. 90majority of Power Board is made up of loose connections or dry connections.

Do this with only AC electricity connected to the main supply. The power board must be changed if a voltage is lacking or rapidly changing.

It’s rather simple to analyze and fix your TV motherboard. A multi-meter, parts and accessories are all you’ll use. It’s important to know that your TV may sometimes show experiences similar to a broken mainboard as a result of a software issue that requires upgrading.

13. Check the TV Installation

You should double-check that your Sharp TV is properly installed. The majority of TV mounting solutions may be fitted in an hour or two, while attaching hardware to some external walls, including brick, stone, tile, or concrete, might very well take more time.

The operation could take up to 4 hours or over if your specialist needs to add blocks to the installation location for additional stability.

When you’re ready to hang the TV, use a stud locator to identify the studs in your wall and figure out where to place it. Do not try to attach it using drywall anchors. The fasteners will end up pulling through the drywall, and your TV will fall to the floor

14. Check the TV Installation

As said earlier, you need to examine if the problem is not as a result of a bad installation. It’s a easy procedure, but getting it correctly might help bridge the gap between a nice-looking TV and one that doesn’t sit right or even gets damaged.

When you’ve found the appropriate position on the wall, you’ll have to locate the studs in order to effectively install the bracket.

15. Replace Sharp TV

There are situations whereby your sharp TV cannot just come on anymore because it does not require a repair but a replacement. All you have to do is replace the old sharp TV that is not turning on with a new Samsung 2021 model (view on Amazon).

16. Contact Sharp

If your Sharp TV still won’t switch on, you may reach the Sharp customer services. Their customer service number is 1-888-935-8880.
