Sanyo TV Won’t Turn On: Try These Fixes

By SmartHomeBit Staff •  Updated: 09/23/22 •  7 min read


1. Power Cycle Your Sanyo TV

When you turn your Sanyo TV “off,” it isn’t truly off.

Instead, it enters a low-powered “standby” mode that allows it to start up quickly.

If something goes wrong, your TV can get stuck in standby mode.

Power cycling is a fairly common troubleshooting method that can be used on most devices.

It can help fix your Sanyo TV because after continuously using your TV the internal memory (cache) may be overloaded.

Power cycling will clear this memory and allow your TV to run like it’s brand new.

To wake it up, you’ll have to perform a hard reboot of the TV.

Unplug it from the wall outlet and wait for 30 seconds.

This will give time to clear the cache and allow any residual power to drain from the TV.

Then plug it back in and try to turn it on again.


2. Replace the Batteries in Your Remote

If power cycling didn’t work, the next potential culprit is your remote.

Open the battery compartment and ensure that the batteries are fully seated.

Then try pressing the power button again.

If nothing happens, replace the batteries, and try the power button once more.

Hopefully, your TV will turn on.


3. Turn Your Sanyo TV on Using the Power Button

Sanyo remotes are pretty durable.

But even the most reliable remotes can break, after prolonged usage.

Walk up to your TV and press and hold the power button on the back or side.

It should power on in a couple of seconds.

If it doesn’t, you’ll need to dig a bit deeper.

4. Check Your Sanyo TV’s Cables

The next thing you need to do is check your cables.

Inspect both your HDMI cable and your power cable, and make sure they’re in good condition.

You’ll need a new one if there are any horrendous kinks or missing insulation.

Unplug the cables and plug them back in so you know they’re properly inserted.

Try swapping in a spare cable if that doesn’t fix your problem.

The damage to your cable could be invisible.

In that case, you’d only find out about it by using a different one.

Many Sanyo TV models come with a non-polarized power cord, which can malfunction in standard polarized outlets.

Look at your plug prongs and see if they’re the same size.

If they’re identical, you have a non-polarized cord.

You can order a polarized cord for around 10 dollars, and it should solve your problem.


5. Double Check Your Input Source

Another common mistake is using the wrong input source.

First, double-check where your device is plugged in.

Note which HDMI port it’s connected to (HDMI1, HDMI2, etc.).

Next press your remote’s Input button.

If the TV is on, it will switch input sources.

Set it to the correct source, and you’ll be good to go.


6. Test Your Outlet

So far, you’ve tested many features of your TV.

But what if there’s nothing wrong with your television? Your power outlet may have failed.

Unplug your TV from the outlet, and plug in a device that you know is working.

A cell phone charger is good for this.

Connect your phone to the charger, and see if it draws any current.

If it doesn’t, your outlet isn’t delivering any power.

In most cases, outlets stop working because you’ve tripped a circuit breaker.

Check your breaker box, and see if any breakers have tripped.

If one has, reset it.

But keep in mind that circuit breakers trip for a reason.

You’ve probably overloaded the circuit, so you may need to move some devices around.

If the breaker is intact, there’s a more serious problem with your home’s wiring.

At this point, you should call an electrician and have them diagnose the problem.

In the meantime, you can use an extension cord to plug your TV into a working power outlet.


7. Check Your Sanyo TV’s Power Indicator Light

Your Sanyo TV’s indicator light will turn different colors depending on its status.

An inactive power indicator light is a surefire sign that your power supply is damaged.

In that case, you’ll need to file a warranty claim or have your TV serviced.


Blue Status Light is on

A blue status light could indicate an overcharged capacitor on your main board.

Unplug the TV for an hour to let it discharge, then plug it back in and see if it works.

If it still won’t turn on, your mainboard needs a replacement.


Green Status Light is on

A green status light could mean many things, from minor issues to severe ones.

You’ll have to work through the other steps in this guide, including a factory reset.


Red Status Light is Flashing

To fix a flashing red status light, first, unplug your TV from the power outlet.

Get rid of any power strip or extension cord, and make sure you can plug your TV directly into the wall.

But don’t plug it in yet.

Press and hold the power button on the TV for 15 seconds, and release it.

Do this three more times, then wait for five minutes, plug in the TV, and turn it on.

If this doesn’t work, there’s a serious electrical problem.


8. Factory Reset Your Sanyo TV

Your Sanyo TV has a reset button on the back, near the input and output ports.

It’s a small pinhole, and you’ll need to activate it with a paperclip or other small object.

Hold the button until you see a Sanyo logo on the screen.

A reset will fix many issues, but remember that you’ll have to re-configure all of your settings.


9. Contact Sanyo Support and File a Warranty Claim

A storm or power surge can cause damage to your TV’s motherboard or power supply.

In that case, you’ll need to have it repaired.

You can contact Sanyo via their web form if your TV is still under warranty.

Alternatively, you can call (866) 212-0436 from 10 AM to 7 PM Eastern time, Monday through Friday.

Sanyo’s warranty is one year for parts, 90 days for labor, and two years for the picture tube.

You may be able to return your TV to the store if you purchased it recently.

If worse comes to worst, you can always have it repaired at a local shop.


In Summary

In most cases, you can fix your TV by power cycling it or attempting one of the other simpler solutions.

But even if it’s something more complex, like a failed main board, it’s not the end of the world.

With the right parts and expertise, you can fix just about any TV.
