Is your Hitachi TV not turning on after you’ve switched it off normally, and now it won’t turn on and it’s stuck in standby mode?
You can encounter this problem due to several factors ranging from minor software issues to hardware issues, although in most cases it can be corrected at home.
First and foremost, you need to identify the symptoms such as whether there is a red light, blue light, or no light and the TV will not turn on.
In the past, I had a Hitachi Plasma TV and experienced the same issue and fixed it at home, luckily it was not a major issue.
I found out later that it is a fairly common issue that is being reported by many Hitachi TV users with Ultravision, Plasma, and old Hitachi TV models.
Throughout this guide, I will explain why this happens, and what you can do when your Hitachi TV won’t turn on or is stuck on standby mode.
I have split the guide up in a way that will allow you to identify the issue and fix it on the first try.
How to fix a Hitachi TV that won’t turn on?
If you want to resolve the issue, you will first have to identify the root cause. However, I understand that there are some of you who are unfamiliar with the power connection functioning, so the guide below explains how to do this.
It can be anything from a weak power supply to faulty cables, to a malfunctioned TV power board which can cause your Hitachi TV not to turn on. You need to verify all the power supply connections and power cables carefully in order to solve it.
I have outlined below a 10 point checklist that you should follow in order without skipping any points.
1. Check the power source
Ensure that the power source through which your TV is connected is in good condition and does not have any problems.
Following these steps will allow you to test the power source and make sure that it is working.
- The first thing you need to do is turn off the circuit breaker.
- After that, disconnect your Hitachi TV for 20 seconds before reconnecting it.
- If you can turn it on, then the problem is more likely not with the Hitachi TV but rather with your electrical system.
- In case it does not work, then you might need to call an electrician or the TV may be faulty.
2. Check the power cord
You should check your TV’s power cord if your power supply is in good shape and you have even tested it by plugging in any other device.
Generally, you need to check whether the plug is plugged in correctly and if it has any loose or damaged connections. Do a visual check for dirt or debris on the plug itself.
3. Check the connections of Hitachi TV
Make sure all the connections are tight on your Hitachi TV, and if you have spare cables, replace them, as the power cable is detachable on some Hitachi TVs.
You should also inspect the electrical connections by the power cord from the TV to the power outlet.
4. Check the power button on Hitachi TV
Another thing to check if your Hitachi TV won’t start is its power button. Make sure it’s not stuck or dirty.
In the event that the Hitachi TV does not turn on immediately upon pressing the power button, simply clean the button or press it for about 20 seconds to perform a soft reset.
Using a toothbrush or your fingers should be enough to do this without using any tools.
5. Power Cycle or Soft Reset
In certain cases, the power socket gets dirty or jammed with debris, which prevents the power supply from reaching your TV.
Additionally, if there has been a recent power outage or a power failure, this can conflict with the TV settings, so it stops responding and won’t get switched on.
Performing a soft reset and cleaning the port may help you turn on the TV again.
Wait for 2-3 minutes before plugging the Hitachi TV back in and turning it on. After that, plug it back in and turn it on.
Also, after you have removed the power cable, press the power button on your TV for 20 seconds, and that will soft reset the TV.
If you are using a surge protector, It is important to take care of surge protectors.
If you have surge protectors on your home or office electrical system, be sure they are not causing problems. If they do, unplug them and clean them again.
6. Check the fuse
Whenever your TV does not show any red or blue light, you need to check the fuse.
So, locate the fuse. It’s a little black thing that looks like a match head. It’s found on the circuit board of the Hitachi TV cabinet.
- Remove the faceplate of the Hitachi TV first.
- After that, remove the four screws holding the faceplate in place.
- When you lift up the faceplate you will find a small black box with a few thin wires coming out of it.
- These thin black wires connect to the fuses.
- You should now check the fuses. A green fuse is always OK, while a red or black one is usually blown.
7. HDMI Glitch
If you are able to see red or blue light but still the TV is not turning on after you press the Power Button then the HDMI cable might be the reason.
HDMI glitches can also prevent your Hitachi TV from turning on.
This can be fixed by unplugging and plugging back in the Hitachi TV after it has cooled for ten seconds, and then turning it back on.
8. Surge Protector Failing
As the name suggests, a surge protector functions as a battery-backed circuit breaker.
It is possible for your Hitachi TV to be unable to receive power if it is not working properly. You can have a dead short or open circuit.
In this case, it is necessary to replace the surge protector.
Wrapping It Up
There can be a number of reasons why your new Hitachi Smart TV or older TV model will not turn on despite the lights being illuminated red, blue, or sometimes not at all.
In this guide, I have shared the 8 things you should do if your TV isn’t turning on, and I hope you’ll be able to fix it with these steps.
In rare cases, you may have to contact support as power supply or board problems cannot be excluded.
