In this article, you’ll know how to fix this problem. So, if you wake up to your Hisense TV not turning on, continue reading.
Why My Hisense TV Won’t Turn On?
To successfully solve any problem, the first thing to know is its underlying cause. Below, we will list the reasons why your Hisense TV won’t turn on.
- A faulty power cable
- A faulty power outlet
- A bad remote control
- A damaged HDMI port or cable
- Display settings misconfiguration
- A damaged TV back-light
- A hardware problem
What Can I Do If My Hisense TV Won’t Turn On?
You now know the reasons behind your Hisense TV not turning on. Let’s explore practical ways to fix it.
Since there are many problems, there are also many solutions, depending on the situation. We will carefully go over each one.
1. Power Cycle Your TV
A power cycle is another name for a soft reset. This is a simple procedure, but it is very effective.
The need to power cycle your TV occurs due to excess charge building up in it.
Thus, to remove these charges, you would need to power cycle the TV. Below is the procedure to power cycle your Hisense TV;
- Firstly, unplug your TV from the power outlet and leave it for 60 seconds
- Press and hold the power button on the TV (not the remote) for 30 seconds
- Then, plug the TV back into the power outlet or a different one.
Your Hisense TV should come on at this point if the problem is power-related. However, if this doesn’t solve the problem, continue reading for other possible solutions.
2. Change Your Remote Batteries
This is another probable solution to turning on your Hisense TV. This is especially helpful if the red light flashes, but the TV is still not turning on.
Changing the batteries in your remote may sound simple. However, it may be the solution to what you thought was a big problem.
Remote control batteries get weak over time, so you should change them once in a while.
When the battery becomes weak, it temporarily stops working. So, changing it might just work. If it doesn’t, try other solutions.
3. Reset Your Remote
In the same way that a TV accumulates charges, a remote control can also build up charges.
A buildup of charges in your remote control can make it unresponsive. So, you would see the red light flashing on the TV, but it won’t turn on.
To solve this, reset your remote control by doing the next;
- Take out the batteries from the remote
- Then, press and hold the power button for 30 seconds with the batteries still out
- Replace the batteries
- Now, try turning on the TV with the remote.
You may need to repeat this procedure up to five times. This is important to note if it didn’t work on the first trial.
If it still doesn’t work, try opening the remote and cleaning its insides to remove the dust.
4. Plug the TV Into a Different Outlet
If the red light of your Hisense TV is not flashing, the power outlet might be faulty. Check the outlet where you initially plugged in the TV.
Try plugging it into another power outlet and seeing the results. However, if the issue of your Hisense TV not turning on still exists, seek other solutions further down this article.
5. Check Your Power Cable
If your Hisense TV won’t turn on at all, and the red light (standby mode) does not appear, the problem may be from the power cable.
Turn the back of your Hisense TV to see where the power cable plug is. Confirm it has a tight fit by pulling it out and plugging it back in.
Also, confirm that the power cable is well placed in the power outlet, then try turning on the TV.
It should work at this point. If it still doesn’t, we will walk you through other solutions.
6. Check For Defective Blacklight
Another reason your Hisense TV does not turn on is a defective backlight. But, you can only check this if your TV can enter standby mode in the first place.
When you turn on your Hisense TV and the red light flashes, the TV just came on. However, if you don’t see any images, the problem could be from the backlight. To check this;
Turn on the TV and be sure that all the signs that the TV came on are in place. Then, point a flashlight at the TV screen.
If you see a dim light (mostly blue), it means your TV backlight is not working well. Still, if you only see a reflection of the flashlight and yourself, it shows that your backlight works fine.
If your TV has a faulty backlight, you need the attention of an expert to change it.
7. Check the HDMI Post And Cable
If you are still having problems with your Hisense TV not turning on, there are additional steps you can take. Check the HDMI port. Also, inspect the cable for any issues. In some cases, the HDMI port may not be properly fixed.
In other cases, it may be that the HDMI port is not responsive.
However, you can suspect an HDMI problem when the red light of the TV flashes. The TV still won’t turn on.
Turn the back of the TV to see if the HDMI cable is well-fixed into the port. To be sure, pull it out, then plug it back in.
If that does not do the trick, try plugging the HDMI cable into another HDMI port on your TV.
You may also need to change the HDMI cable. If that solved the problem, congratulations! If it didn’t, try the next set of solutions.
8. Do a Factory Reset
A factory reset may be necessary when you have mistakenly tampered with your screen settings.
Since your Hisense TV won’t turn on, you should do the factory reset without a remote.
There are various ways to do a factory reset on Hisense TV without a remote, depending on the TV model;
Press and hold the reset button for 30 seconds. But, not all Hisense TVs have a reset button.
Look for a reset hole somewhere at the back of the TV. If your Hisense TV has this hole, use a pin to press the button inside. Hold it for 30 seconds.
If there is no reset button, press and hold the input and volume down buttons together for 30 seconds.
Your TV will most likely come on after a reset. If that doesn’t happen, then we are looking at a hardware problem.
9. Check the TV Main Board
If the red light flashes and your Hisense TV won’t turn on, the problem is on the main board. This is true after trying other solutions.
You would need to get a new board entirely. So get a new board and check if it fixes your Hisense TV not turning on.
10. Check the TV Power Board For Faulty Capacitors
In another case where the red light flashes, the TV won’t come on. The issue likely lies with the capacitors. They are on the power board.
Checking for a faulty capacitor may require expert attention. This is especially true if you do not know the first thing about electronic hardware. Otherwise, detecting a faulty capacitor is easy
- Open up the back of the TV.
- Take some pictures of the placement of the capacitors so you can replace them in the appropriate positions afterward.
- Look for any faulty capacitors and replace them with new ones.
Signs to know if a capacitor is faulty:
- The top of the capacitor is bulging.
- The capacitor leaks.
- The corrosive coating on one or both capacitor legs.
- The bottom bung of the capacitor gets pushed out.
- The capacitor has a wrong voltage reading when connected to a multimeter. This gives the most accurate diagnosis, as not all faulty capacitors show visual signs.
Once you have located the faulty capacitor, remove it using a soldering iron. Make sure you do not try to pull it out forcefully.
To remove the capacitor, use the soldering iron. Apply pressure from the back of the board on the pin the capacitor attaches to. Do this until the capacitor melts, then gently take it out.
Also, ensure the new capacitor you want to use has the same temperature, voltage, and microfarad reading.
However, you can go for capacitors with slightly higher ratings if you cannot get those with the same ratings.
Now that you have gotten your new capacitor, place it in the same position as the old one you removed. Try turning on your TV–it should work now.
