Common Reasons for Hisense TV Not Turning On

There are a few likely culprits behind a Hisense TV refusing to start up when you press the power button:

Power Supply Issues

Like any electronic device, a Hisense TV needs power to operate. If the TV is not getting power, it will remain off when you try to turn it on. Some common power supply-related reasons a Hisense TV won’t start include:

• Faulty power cord – If the power cord connecting your TV to the wall outlet is damaged or loosely plugged in, power may not be able to flow properly to the TV.
• Tripped breaker – The circuit your TV is connected to may have tripped its breaker, cutting power to that outlet. Check your electrical panel for any tripped switches.
• Power surge – Nearby electrical spikes or surges could have damaged components that regulate power delivery in your TV.
• Bad outlet – Problems with the specific wall outlet you’re using like loose wiring or no power getting to the outlet at all will prevent your TV from turning on.
• Blown fuse – Internal fuses that serve to protect your TV from power surges may need to be replaced if they’ve blown.

Remote Control Problems

Your Hisense TV remote controls power flow to the TV when you hit the power button. Issues with the remote can cut off that signal and lead to a TV that won’t start up:

• Dead batteries – Replace old, drained batteries in your TV remote. Low battery power may not be strong enough to send the power-on signal.
• Wrong input selected – If your remote has an input button, make sure it’s set to the HDMI or other input your TV source is connected to.
• Pairing issues – Your remote may have lost its pairing connection to the TV, preventing it from controlling power. Re-pair it.
• Faulty remote – If none of the above fixes the problem, the remote itself may have failed due to physical damage or defective components.

Hardware Malfunctions

If power is getting to your TV but it still doesn’t respond to the remote or power button, internal hardware problems are likely to blame:

• Main board failure – The main circuit board that controls your TV could have experienced damaged capacitors, memory issues, fried circuits or other malfunctions.
• Faulty power supply – The internal power supply that transforms AC power into lower DC voltage for your TV may have failed.
• Backlight issues – LEDs or CCFL tubes that illuminate the TV’s backlight may have burnt out.
• Panel failure – The LCD or other display panel itself could suffer physical cracks or broken circuitry preventing video.

Troubleshooting Steps

Before you panic and assume the worst, there are several basic troubleshooting steps you can follow yourself to get to the bottom of why your Hisense TV won’t power up:

1. Power Cycle the TV

Often a simple power reset is all that’s needed to get a TV working again. Power cycle your Hisense TV by:

1. Unplugging it from the wall outlet and disconnecting other power cables.
2. Waiting 30 seconds to 1 minute.
3. Plugging the power cables back in and reconnecting to power.
4. Pressing the power button on your remote or the TV itself to turn it on.

This gives components a chance to discharge accumulated static or reconnect if there are any software issues preventing startup.

2. Check Remote and Replace Batteries

An unresponsive remote is one of the most common reasons a TV won’t turn on. Double check these issues with your Hisense TV remote:

• Try pressing buttons directly on the TV to rule out remote problems. If the TV responds, focus troubleshooting on the remote.
• Install fresh batteries in the remote. Low battery power can prevent signals from reaching the TV.
• Make sure you’re aiming the remote directly at the TV from close range. Weak signals may not be received.
• Re-pair or sync the remote with the TV if that is an option. Syncing establishes remote control.
• Test buttons like volume/channel controls. If some work but power doesn’t, just the power function may have failed.
• If replacing batteries and troubleshooting the remote doesn’t revive it, you may need a new one.

3. Verify Power Source and Cables

Loose connections or improper power sources frequently prevent a TV from turning on:

• Make sure the power cable running from the TV to the wall is firmly inserted at both ends.
• Confirm the power outlet is working by plugging in a different device like a phone charger.
• Try connecting the TV to a different outlet you know works properly.
• Use the original power cable that came with your Hisense TV if possible. Incorrect cables can prevent startup.
• Check for tripped breakers in your electrical panel cutting power to the outlet in use.
• If connected through a power strip, bypass it and plug the TV power cable directly into a wall outlet.
• For sets connected through an A/V receiver, make sure the receiver is powered on before the TV.

4. Reset Your Hisense TV

Resetting your TV restores factory default settings which can resolve software glitches or configuration issues stopping it from starting up. Refer to your TV’s manual for exact reset steps. Common options include:

• Unplug TV power, hold down power button on the TV itself for 10 seconds, then plug back in and power on.
• On the remote, press the Menu button, then select Settings followed by Factory Reset. Confirm reset when prompted.
• Press and hold both volume Up and Down buttons on the TV for 10-20 seconds until the image disappears.

This will wipe all custom settings so you’ll have to redo your setup like input selection and channel tuning. Apps and streaming service credentials will need re-entering as well.

5. Contact Hisense Support

If you still can’t get your Hisense TV to power up after trying all of the troubleshooting steps above, it’s time to contact Hisense Support:

• Call Hisense customer service at 1-888-935-8880 for additional troubleshooting help over the phone.
• Initiate a service request on the Hisense website for a technician visit or repair options.
• Check your TV’s warranty length and coverage. Some power issues may be fixed free under warranty.

Detailed Troubleshooting Methods

For each of the common issues that can prevent a Hisense TV from turning on, more in-depth troubleshooting steps can help narrow down the problem:

Power Supply Issues

Pinpointing power-related problems relies on methodically checking connections and components:

Faulty power cord:

• Visually inspect the power cord for damage like frayed/exposed wires, cuts, punctures, or bent plug prongs.
• Check both ends of the cord to make sure they are fully inserted into the TV and wall outlet. Try unplugging and firmly re-inserting each end.
• Try wiggling the cord near both ends to see if there are any loose connections impacting power flow.
• Test the cord with another device like a phone charger or lamp. If they don’t turn on, the issue is with the cord.
• If damage is found, replace the cord. Use only a cord rated for your TV’s power level.

Tripped breaker:

• Locate the electrical panel and open the cover to reveal the circuit breakers inside.
• Find the breaker controlling the outlet your TV is plugged into.
• Check if the switch is fully in the ON position. If tripped halfway towards OFF, flip it fully OFF then ON again to reset.
• If the breaker was not tripped, switch it OFF then ON anyway as this may fix overload issues.

Power surge:

• Unplug the TV and other nearby devices/appliances on the same circuit.
• Plug in a surge protector power strip. Connect devices through the power strip one at a time to isolate any that trip the strip’s protection again.
• Damaged devices will need professional evaluation for replacement of surge-fried circuitry.

Bad outlet:

• Unplug TV and plug another working device into the outlet like a phone, laptop charger, or lamp.
• If other devices don’t turn on either, the issue is with the outlet or wiring.
• Use a non-contact voltage tester near outlet screws to check for power. No light indicates no power to the outlet.
• Call an electrician to replace the outlet if needed. Faulty outlets can damage TVs and other electronics.

Blown fuse:

• Carefully open your TV’s case cover and locate the fuse housing on the power supply board.
• Remove and visually inspect the fuse for any broken filament inside indicating it’s blown.
• Check fuse amperage rating against service manual specs to replace with the correct fuse.
• Only use a fuse with the specified type, size, voltage, and amp rating to avoid further issues.

Remote Control Issues

For remote problems, be sure to test both the remote and TV functions:

Dead batteries:

• Remove existing batteries and inspect to see if any have ruptured or leaked. Clean residue.
• Insert new batteries that match the rating and type listed in the remote manual. Always replace as a set.
• Test other buttons like channel/volume control to isolate if only the power function fails.

Wrong input selected:

• Check the currently selected input on the TV itself through the on-screen menus or front panel input button.
• Use the remote’s input button to toggle through various inputs like HDMI 1, HDMI 2, etc until finding the one your devices use.

Pairing issues:

• Consult the remote’s manual for how to re-pair or sync it to the TV. This often involves holding down a combination of buttons for 5-10 seconds.
• Try power cycling both the TV and remote by removing/replacing batteries and unplugging the TV for 30+ seconds.

Faulty remote:

• If new batteries and troubleshooting don’t restore function, the remote itself has likely failed internally.
• Button contacts and trace wires can corrode or break over time with use. Electronic components may malfunction.
• Purchase a replacement remote from Hisense certified for your specific model. Only OEM remotes are guaranteed compatible.

Hardware Failure

For suspected hardware issues where the TV won’t power on from either the remote or manual power button, internal electronic testing and repair expertise is needed:

Main board failure:

• Capacitors can bulge/leak, circuits and memory chips can overheat and short out, or solder joints can crack.
• Check for visual signs of burns or damage around components on the main board once the case is removed.
• Proper diagnosis requires testing volts and continuity through board circuits with a multimeter. Replace failed modules.

Faulty power supply:

• Test output voltages from the power supply board to confirm if they deviate from service manual specifications.
• If the power board fails testing, it will need replaced with an identical Hisense model number power supply board.

Backlight issues:

• Shine a flashlight at an angle on the screen. Some image should be faintly visible if it’s only a backlight problem.
• Replace failed CCFL tubes or LED strips. LEDs may need re-soldering if connections have cracked.

Panel failure:

• Check for physical cracks on an LCD panel or burn marks/discoloration on other panel technologies.
• To confirm, panel voltage tests would need to be performed using service manual pinout locations.
• The entire front panel module often requires replacement if video fails to display.

Advanced Troubleshooting

When basic troubleshooting steps haven’t helped resolve your Hisense TV powering on, more advanced techniques can help zero in on potential hardware failures:

Exploring Internal Hardware Problems

Getting inside your TV and testing components requires disassembly skills and electronic troubleshooting know-how:

• Remove the TV’s case back cover to access the internal circuit boards, cabling, and power supply. Use plastic pry tools to avoid damage.
• With the power unplugged, visually inspect boards for damage like leaking capacitors or burnt spots. Burn marks can signify short circuits.
• Use a multimeter to test output voltages of internal components like fuses, rectifiers, and voltage regulators when the TV is plugged in.
• Check continuity of traces between components and boards. Broken solder joints or corroded pins can break these essential connections.
• Compare voltages and resistance measurements to service manual specifications to identify components outside normal parameters.
• Replace boards or parts that fail testing. Only use identical Hisense replacement parts to ensure compatibility.

When Professional Repair Is Needed

While many issues can be identified visually or with simple tools, more in-depth repairs call for an experienced technician:

• Diagnosing intermittent, temperature-related, or very short failures often requires oscilloscopes, signal generators, and specialized tools.
• Some circuit tests are most easily performed with the TV fully assembled and may be very difficult with the case open.
• Technicians have access to proprietary service information directly from Hisense for troubleshooting rare failures.
• Proper microsoldering skills are needed for repairing modern circuit board components and connection points.
• TV repair poses electric shock risks and requires training in safely handling high voltage areas.

Seeking professional TV repair services is recommended once you’ve exhausted DIY troubleshooting without success. Hisense can help locate certified technicians in your area.

How to Reset a Hisense TV
