A Toshiba TV flashing red and green is, unfortunately, never going to be a good sign. In most cases, it indicates that there is something seriously wrong with your television.
If you notice that your Toshiba TV is flashing red and green, it is likely there is a problem with the PCB inside the TV.
This means that you may need to take your television to be repaired.
Why Does This Happen?
There are two types of ‘flashing red and green’ here.
We know that some people may mean different things, so let’s break down the two main causes.
Your Screen Is Flashing Red and Green
If the screen is flashing red and green then, in the vast majority of cases, this is due to an issue with the HDMI cable.
The HDMI cable may be damaged, or it may not be connected properly.
In rare cases, it may be because the television screen has been damaged.
However, if you weren’t moving around your TV before this problem occurred, then we highly doubt that this is going to be the root of your problems.
TVs don’t randomly break down, and there will often be quite a few warning signs before this problem starts to occur.
The Power Indicator Light Is Flashing Red and Green
If the power indicator light on your Toshiba TV is flashing red and green, then you have some serious issues.
Toshiba’s lights are meant to flash ‘error codes’, and flashing between red and green is the absolute worst that there can be.
In most cases, it means that the PCB inside the TV has become damaged.
There may also be an issue with the power getting into the television.
Honestly, it is pretty tough to know exactly why the power indicator light on your Toshiba TV is flashing red and green.
We can tell you that it indicates some serious problems with the television but, as a layman, you probably shouldn’t start to poke around on the television too much.
If you don’t know what you are doing, then you have no idea how to diagnose the problem, and there is a pretty strong chance that you could end up injuring yourself.
How To Fix The Issue?
As we mentioned before, there are a couple of reasons why your Toshiba TV could be flashing red and green.
Well, there are a couple of types of red and green flashing that you will see on your television.
We will break down how to fix the problem in the following categories.
We hope the information will help you out.
The Screen Is Flashing Red and Green
As you know by now, if your screen is flashing red and green, then this is likely going to be down to the fact that an HDMI cable has either been knocked loose, or it is damaged.
When an HDMI cable doesn’t make a complete connection (for whatever reason), some of the colors can be removed from the image that hits the screen, and, in most cases, this is going to cause red and green flashing.
Thankfully, this problem isn’t too tough to fix.
You can do two things here.
Firstly, we suggest that you try and push the HDMI cables in securely.
This means that the one that is connected to the TV, as well as the one that is connected to your video output device.
If that doesn’t seem to help, then swap the HDMI cable out for a different one.
This is something that should fix the problem for you.
If you are still suffering from issues, try and hook another device up to your TV.
See if that gives you issues. If it does, then you may have a faulty TV.
The Power Lights Are Flashing Red and Green
If the power light is flashing red and green on your TV, there is one thing that you can do before you get in touch with Toshiba.
This is to turn the TV off at the wall and completely unplug it.
Leave it unplugged for about a minute, and then plug everything back in. This may fix the problem.
If that doesn’t seem to work then, sadly, you have a faulty TV.
If you have a warranty on your TV, then you may need to get in touch with Toshiba.
If you don’t, then talk to a repair agent.
Tip: If you are using a cable box or have any kind of streaming device connected to your TV, we recommend disconnecting them together with unplugging the TV from the wall socket.
Check the Settings
This is not a very likely scenario, but we will mention it just in case.
Go into your TV’s setting and check that you don’t have a Sleep timer or Energy saving/Low power mode set up.
These setting are notorious for making the TV shut down at random moments.
Inspect the Remote
This is one more thing to watch out for when trying to fix your TV that keeps flashing red and green.
It is possible that the remote is faulty and keeps sending the signals to the TV, causing it to malfunction.
We suggest you take the batteries out of the remote, press each and every button on it a few times to make sure none of them got stuck.
You can give your remote a good shake, it can help if something inside the remote accidentally got stuck or disconnected.
Finally, place a new set of batteries into the remote and see if the situation improves.
Tip: We suggest you combine this step with unplugging your TV from the power outlet, so you have a complete reset.
A Toshiba TV that is flashing red and green is never a good sign. In an ideal scenario, you just have a dodgy HDMI cable.
In the worst-case scenario, you are going to need to look into either getting your TV fixed or replaced.
It means the internal PCB is damaged.
