Why Does Your Hisense Roku TV Keep Turning On and Off?

Hey there! If you’re having trouble with your Hisense Roku TV acting all wonky by turning on and off by itself or just restarting like a broken record, don’t worry, we’ve got your back. In this easy-to-follow guide, we’re going to help you fix this issue, and you’ll be back to watching your favorite shows and sports in no time – all in less than five minutes!

What’s Causing Your Hisense Roku TV to Play This On-and-Off Game?

Let’s break it down in simple terms. Why is your TV doing this crazy on-and-off dance? Well, it could be a few things:

  1. Unsteady Power Supply: Imagine if the electricity in your house was like a rollercoaster going up and down. That’s what can happen to your TV if there are sudden power surges or changes in voltage.
  2. Wonky Power Cord: Your TV’s power cord needs to be snug as a bug in a rug. If it’s not plugged in properly or if the cord itself is damaged, it can cause the TV to go haywire.
  3. Troublesome Power Port: Even if the cord looks fine, there might be an issue with the place where it plugs into your TV. If that’s messed up, your TV might act up.
  4. Software Gremlins: Sometimes, it’s not a hardware problem; it’s a software hiccup. Just like your computer or phone can freeze or act weird, your TV’s software can do the same, making it turn on and off.
  5. Capacitor Confusion: Inside your TV, there’s a little part called a capacitor. If it’s not working right, your TV might have a hard time starting up and might keep restarting.

But Wait, Sometimes It Turns Off Every 5 Seconds?!

Yeah, it can get even more annoying if your TV decides to play the “off and on” game every 5 seconds. That’s like trying to watch a movie with a remote control that’s gone crazy! But don’t worry, we’ll help you sort it out.

How Can You Stop Your Hisense Roku TV from Acting Up?

Hey, there! If your Hisense Roku TV is giving you a hard time by constantly turning on and off, don’t worry! We’ve got some straightforward solutions that’ll help you fix it.

1. Power Cycle Your TV: What’s That?

Sometimes, your TV needs a little reset, just like when you restart your computer. Here’s how to do it:

  • Unplug your Hisense Roku TV from the wall. Yep, just pull that plug out.
  • Now, press and hold the power button on the TV itself for about 30 to 45 seconds. Make sure it’s the TV’s power button, not the one on the remote.
  • After waiting a bit, plug your TV back in and turn it on. Let’s see if it’s still misbehaving.

2. Make Sure the Power Cable Is Snug as a Bug:

The power cable (that cord that brings electricity to your TV) should be snugly connected and not damaged. Here’s what to do:

  • First, unplug the power cable.
  • Check the ends of the cable for any dust or dirt. Clean it if needed.
  • Plug the cable back into your TV and make sure it’s in there really well.
  • Examine the cable itself. Is it damaged or frayed? If it is, you might need a new one.
  • If you’re using an extension cord, try plugging your TV directly into the wall to see if that helps.

3. Unplug Other Devices and Turn Off HDMI-CEC:

Sometimes, other devices connected to your TV can cause this on-and-off madness. If you’ve got things like a PlayStation, Xbox, or Blu-ray player hooked up, give this a try:

  • Disconnect all those other devices from your TV.
  • Unplug your TV and plug it back in.
  • Turn it on and see if it behaves better.
  • If your TV has HDMI-CEC (a feature that lets devices control your TV), you might want to turn it off if you’re not using it.

4. Test a Different Power Outlet:

Your TV might not be getting consistent power from the wall. Try this:

  • Unplug your TV.
  • Plug it into a different power outlet to see if that solves the problem.
  • If you were using an extension cord, try a different one or plug directly into the wall.

5. Hard Reset Your Hisense Roku TV:

If all else fails, you can try a hard reset. Be careful, though, because this will erase all your settings and log you out. Here’s how:

  • Find the “Reset” button on the back of your TV, usually next to the HDMI and audio ports.
  • Get a pin or something small and pointy.
  • With your TV plugged in and turned on, press and hold that reset button for about 10 to 20 seconds.
  • Let go when you see the Hisense Roku TV logo on the screen.

7. Replacing Faulty Capacitors: A Techie Task

Okay, so here’s the scoop: sometimes, if the capacitor in your Hisense Roku TV’s display panel goes bad or blows up, it can cause that annoying on-and-off dance. Replacing these capacitors might sound tricky, but we’ll break it down for you.

Important Note: If your TV is still under warranty, don’t mess around with it. Contact customer support instead.

Before You Dive In: Drain That Power!

Before you open up your TV, you need to make sure there’s no sneaky power left inside. Here’s what to do:

  • Unplug your TV, of course.
  • Press and hold the power button on the TV for about 30 to 45 seconds.
  • Once you’ve done that, you’ve drained any leftover power.

Now, Let’s Get Technical:

  • Lay your TV down on a soft surface with the screen facing down.
  • Start unscrewing all those screws on the back panel of your TV.
  • Carefully remove all the cables that connect different parts inside, like the boards, speakers, Wi-Fi modules, and so on.
  • Check out the capacitors on the power supply board of your TV. Look for any that are bulging at the top or leaking. If they look swollen or gooey, they’re probably faulty.
  • To be super sure, you can use a tool called a multimeter to check the voltage. If it doesn’t match the labeled voltage on the capacitor, it’s faulty. If it’s totally dead, the multimeter won’t show any reading at all.

Time to Swap ‘Em Out:

  • Now, you can’t just put any old capacitor in there. It has to match the specs of the one in your TV – like voltage, temperature, and microfarads. So, make sure you buy the right one.
  • Get a soldering iron (be careful, it’s hot) and gently remove the faulty capacitor by heating up its legs.
  • Be super careful to mark the exact spot where the capacitor goes on the motherboard.
  • Once the legs are heated up, gently pull out the old capacitor.
  • Take your new capacitor, align it correctly with the pins, and use the soldering iron to attach it to the motherboard.

Don’t Want to DIY? No Worries:

If all this sounds too complicated, no problem! You can take your TV to a nearby electronics service center and have them fix it for you. It might cost you around $50 or more, depending on how complex the job is.

8. Still Stuck? Contact Support:

Even after all these steps, if your Hisense TV just won’t behave, it’s time to call in the pros. Get in touch with customer support at this number:

What’s Next?

Fixing a Hisense TV that’s acting up and turning on and off doesn’t have to be a big headache. Usually, a quick power cycle will do the trick.
