Your Westinghouse TV won’t turn on because the cache is overloaded which is preventing your device from booting up. You can fix your Westinghouse TV by power cycling it. First, unplug your TV’s power cord from your outlet and wait 45 to 60 seconds. Waiting the appropriate amount of time is important as it allows your TV to fully reset. Next, plug your power cable back into the outlet and try turning the TV on. If this doesn’t work, double-check that all your cables are securely plugged in and test your power outlet with another device
1. Power Cycle Your Westinghouse TV
When you turn your Westinghouse 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 Westinghouse 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 Westinghouse TV on Using the Power Button
Westinghouse 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 Westinghouse 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 Westinghouse 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.
Make note of 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 your problem will be solved.
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 Westinghouse TV’s Power Indicator Light
Like most TV manufacturers, Westinghouse has built an indicator light into their TVs.
Knowing whether the light is on or off can help you to solve your problems.
Red Standby Light is on
It’s good news if your red standby light is lit up.
That means your power supply board is working.
Unfortunately, your main circuit board may have failed.
Here’s how to diagnose the problem:
- Unplug your TV from the wall outlet.
- Wait for a minimum of 60 minutes.
- Press and hold the power button on the TV for 60 seconds.
- Keep holding the button down and plug the TV back in. Do not use a power strip, surge protector, or extension cord.
- Hold the button for an additional 60 seconds.
If that doesn’t work, try this method:
- Press and hold your TV’s volume and menu buttons simultaneously.
- Press and hold the power button for five seconds, then release it.
If neither of these methods worked, your main circuit board failed.
You’ll need to order a new board and replace it yourself or take it to an electronics repair shop in your city.
Red Standby Light is off
Dead standby lights are bad news; it means your power supply board has failed.
It may be the entire board, or it could be an individual transistor, diode, or cathode.
Either way, you’ll need to replace the broken part.
Diagnosing individual cathodes and other small parts is for experts only.
But it’s easy for anyone to replace the power supply board.
All you need are a few tools, a replacement power supply, and a towel to protect your TV screen.
8. Factory Reset Your Westinghouse TV
If all else fails, you can factory reset your TV.
Keep in mind that this is not something you should do lightly.
You’ll lose any data you have saved, along with all of your settings.
But sometimes, it’s the only option.
Look on the back of your TV for a small pinhole.
Use a pin, paperclip, or another tool to press and hold the button inside for 10 seconds.
Wait a few minutes for your TV to reset, and it should start back up.
9. Contact Westinghouse Support and File a Warranty Claim
In some cases, a storm or a power surge could overload your TV’s electronics.
In that case, a repair is your only option.
Westinghouse provides a 1-year warranty, so you can file a claim if your TV is new.
Even after that, you can contact Westinghouse through their support page to get help.
You can also call customer support at (800)-701-0680.
You may also consider returning the TV to whoever sold it to you.
Without a warranty or return, you’ll have two remaining choices.
Buy a new TV, or have yours repaired.
There are many possible reasons your Westinghouse TV might not turn on.
To find out why you’ll need to try several solutions.
With luck, you won’t have to take any drastic measures like a factory reset.
