If you’re like me, you’ve noticed the lights on your Sharp TV serve as a communication tool.

They tell us when operations are normal, and importantly, when something goes wrong.

In particular, a persistent flash of the OPC (Optical Picture Control) light on your Sharp TV is a sign you need to troubleshoot a Sharp TV with the OPC light flashing.

This continuous flashing is your TV crying out for attention.

Your mission?

Pinpoint the problem and find a resolution.

The culprit behind these flashing lights could be a hardware malfunction or an issue with the installed firmware on your television.

But don’t worry, once we identify the issue, we can work on a solution together.

Isolating the Issue

Troubleshoot a Sharp TV With the OPC Light

Picture this.

Your Sharp TV won’t power up, the power lights flash incessantly, or some other anomalies occur, all in tandem with a blinking OPC light.

In such scenarios, your first step should be to determine whether the problem is hardware or firmware related.


Try feeling the TV.

Excessive heat could suggest a hardware problem such as a broken fan or another malfunctioning part. If the television isn’t overheating or making strange sounds, the issue might just be related to the firmware or updates.

System Reset and Updates

Before you run off to shell out big bucks on physical repairs, let’s try a full reset and any available updates.

Here’s how you can initiate a power cycle reset: unplug the TV, wait a few moments, then plug it directly into the wall outlet.

This step helps rule out any issues with a faulty power strip. Power the TV back on and check the light.

Still, flashing?

It’s time for a factory reset. It means you’ll lose all saved data and return the TV to its original factory settings.

Yes, it’s a big step. You’ll lose saved apps and passwords. But it might just be the clean slate your TV needs.

  • To conduct a factory reset, unplug the power again. Hold down the “input” and “channel down” buttons on your remote control together, plug the TV back in, and keep these buttons pressed as the TV boots up. Select “Service Mode” from the menu, followed by “Factory Reset”. Wait until the TV restarts before checking the OPC light.

Hardware Troubles

So, you’ve done the full reset but still face the problem?

Your TV might have a hardware malfunction. Hardware repairs require specialty parts and the skills to disassemble the TV to replace them. It’s not something for the faint-hearted or the unskilled.

You might want to have your TV assessed by a professional.

They’ll give you a repair quote, and then you can decide if the repair cost justifies the hardware’s value. In some cases, it’s more beneficial to check if your TV is under warranty or even consider a replacement.

Troubleshooting a Sharp TV with the OPC light flashing might seem like a daunting task, but with a systematic approach, you can do it.

And remember, it’s okay to ask for professional help when needed. Good luck!
