Several reasons can explain why your JVC TV won’t turn on, including power problems, software glitches, and remote control issues.
However, you can easily troubleshoot and resolve several issues before considering other, more expensive solutions.
Some top solutions you can attempt include changing the remote batteries, replacing power cords, power cycling your TV, and more.
Below is a detailed look at these troubleshooting steps and solutions and how they can help you get your JVC TV back into a working state.
Basic Troubleshooting Guide
If your JVC TV is not turning on, try the following simple troubleshooting solutions:
- Ensure the TV’s power cord is plugged into an electrical outlet and the TV power input port.
- Use the power button on the TV itself to turn it on instead of using the remote control.
- Ensure that the batteries on your TV’s remote are working; if not, replace them.
- Make sure you have selected the right input for your JVC TV.
- Check that the HDMI or video cables on your TV are connected properly.
If the troubleshooting steps mentioned above are working, you should try the following more advanced solutions:
1. Ensure That Your TV Is Getting Power
Inadequate or lack of power supply is a common reason for your JVC not turning on. Several issues can cause this, from faulty electrical outlets to faulty extension cords and power cables.
One of the first things you should do is check that your electrical outlet is working correctly. You can do this using an outlet tester, a multimeter, or by plugging in another device, such as your phone’s charger.
If the outlet has power, the problem could be with the extension cord or other surge protectors you use. While these are helpful, they can sometimes interrupt the power flow, causing your TV not to turn on.
Therefore, you can remove the extension cord and surge protectors, connect your TV directly to the wall outlet, and try turning it on. If this does not work, you should check that your TV’s power cord is not faulty.
Examine your TV’s power cord for signs of damage, such as broken or exposed wires. If you notice any issues with the cord, replace it with a new one, then try turning on your TV.
2. Power Cycle Your TV
If your TV receives power but won’t turn on, you can try to power cycle (or reset) it. To do this:
- Turn off your TV.
- Unplug the TV’s power cord from the extension cord or electrical outlet.
- Press and hold the power button (on the TV, not the remote) for 15-30 seconds.
- Wait about 1-2 minutes, then plug back in the power cord and turn on the TV.
Power cycling discharges any residual electrical charge in your TV’s power supply unit. This can help to fix and turn on your TV by:
- Getting rid of electrical spikes: Built-up electrical charge in your TV can cause your device to malfunction. Discharging the TV can thus fix this issue, allowing it to turn on.
- Resetting the power supply: The power cycle also resets the power supply, which can resolve any glitches, like a stuck relay or faulty voltage sensing, that could be causing your TV not to turn on.
- Fixing software glitches: Power cycling also resets your TV’s microcontroller, which can clear any software or firmware issues that could be causing your device not to turn on.
- Re-initializing the power-on sequence: Your JVC TV might fail to turn on due to a faulty power-on sequence. However, after power cycling, the device will re-initialize the sequence again, thus allowing it to turn on normally.
Power cycling can also help fix other issues, such as a faulty or stuck power button or removing your TV from standby mode.
3. Allow Your TV to Cool Down
Overheating is another common reason your JVC TV won’t turn on. The built-up heat in the TV can trigger safety protocols such as automatic shutdown to prevent heat damage.
If your TV won’t power on because of overheating, the most effective solution is to disconnect it from the power source and allow it to cool. This cooling period can range from 30 minutes to several hours or overnight.
Besides allowing your TV to cool down, you can also prevent further overheating through simple solutions like:
- Place your TV in a well-ventilated area. It should also not be too close to walls, curtains, furniture, or other objects that can block the air vents.
- Place your TV away from direct sunlight or other electrical devices emitting heat.
- Turn off your TV when not in use. The longer you use your TV, the more heat it will accumulate.
- Use cooling fans or AC to keep the area around your TV cool.
If your TV constantly overheats, it could be a sign of a more serious internal hardware issue. Therefore, it is advisable to call an authorized technician to check on your device.
4. Check That the Backlight Is Working Correctly
If your JVC TV does not turn on but has a red or blue light, you could have a backlight failure.
However, you can perform a backlight test before you call a technician. First, connect your TV to an input device, such as a streaming device, gaming console, or Blu-ray device, and start playing media.
If you can hear sound playing, you have a faulty backlight, but the screen is black.
You can also perform a flashlight test to confirm if your TV’s backlight is faulty. To do this:
- Turn on your TV and connect it to a device with playing media.
- Turn off (or dim) the lights in the room.
- Shine a flashlight onto the TV screen and check if you can see signs of faint images.
If you can see faint images, your TV’s backlight is faulty. Unfortunately, fixing this requires technical know-how, so it’s best to call a technician or take your device to an authorized service center for repairs.
5. Call a Technician for Repairs
Besides a faulty backlight, several other hardware issues can cause your JVC TV not to turn on. These include:
- Faulty power supply unit
- Faulty motherboard
- Damaged capacitors
- Physical damage due to your TV falling down
These issues require technical expertise to fix; trying to repair them yourself can void your warranty or cause further damage to your TV.
Therefore, you are better off calling a technician or taking your TV to an authorized repair service center.
