What Causes a Sharp Roku TV To Flash Logo Then Go Black?

There are several potential causes for a Sharp Roku TV flashing its logo then going black. These include:

• A malfunctioning power supply.

If this does not resolve the issue then you may need to check if your television software needs updating by checking in your settings menu or downloading any firmware updates available online. If you are still having issues after updating your software then it may be necessary to contact customer support for further assistance with troubleshooting your device.

Understanding the Issue

If you have a Sharp Roku TV and it flashes the logo and then goes black, you may be experiencing one of several problems. It is important to understand what is causing the issue in order to determine how to remedy it. It could be caused by a faulty power supply, a malfunctioning display panel, or even a software issue with the TVs operating system.

Power Supply

If the Sharp Roku TV is not receiving enough power to turn on, it will flash its logo and then go black. To check if this is the case, try plugging in another device that requires the same amperage into the same outlet. If your TV still wont turn on, then it could be an issue with either its power cord or outlet.

If you have another power cord thats compatible with your Sharp Roku TV, try using that one instead. If your TV still wont turn on, then it may be an issue with your outlet or its wiring. You may need to contact an electrician or contact Sharp for assistance if this is the case.

Display Panel

If your Sharp Roku TV flashes its logo and then goes black due to a malfunctioning display panel, there are several possible causes:

Backlight Inverter Failure

The backlight inverter failure occurs when one of the two lights used to illuminate the LCD display fails. If this is happening with your Sharp Roku TV, it may cause it to flash its logo and then go black after a few seconds. To check if this is the case, you can use a flashlight and look at the screen while pressing any buttons on your remote control. If you see nothing but darkness when you press any buttons, then backlight inverter failure could be causing your issue.

Bad Bulb

Another possible cause of flashing logos and then going black on a Sharp Roku TV is a bad bulb inside of the LCD display panel. This can happen when either one of more of them has been damaged or burnt out due to age or a power surge/spike. Unfortunately, replacing them requires disassembling parts of the LCD panel itself which should only be done by qualified personnel as improper handling can cause further damage to other components inside of your television set.

Faulty Capacitors

Faulty capacitors are another possible cause for flashing logos and going black on a Sharp Roku TV set as they help regulate voltage throughout different parts of its circuitry board which includes powering up certain components such as backlights for example.

Software Issues

Software issues can also be responsible for flashing logos and going dark on some models of Sharp TVs powered by their proprietary operating systems such as Android TVs for example.

In this case updating or resetting its software might help resolve this issue if all else fails.

Conclusion

In conclusion, if your Sharp Roku TV flashes its logo and then goes black there could be several possible causes including faulty power supply issues or malfunctioning display panel components such as bad bulbs or faulty capacitors as well as software related issues which might require resetting/updating its firmware in order to fix them properly.

It’s important that these types of issues are taken care off by qualified personnel only so make sure you contact support from either side (Sharp/Roku) before attempting any repairs yourselves in order avoid further damage and unnecessary costs down the line!
