Step-by-Step Troubleshooting for Hisense TV Not Turning On
1. Perform a Soft Reset
Sometimes, the TVās internal memory or firmware might freeze, preventing startup.
- How to Soft Reset:
- Unplug the TV from power.
- Wait for at least 60 seconds.
- Press and hold the TVās physical power button for 15 seconds to drain residual power.
- Plug the TV back in and press the power button again.
Soft reset can resolve minor firmware glitches and is often the quickest fix.
2. Hard Factory Reset (If TV Powers On But Wonāt Respond)
If your TV turns on but doesnāt respond or shows a black screen, try a factory reset.
- Navigate to Settings > System > Reset & Admin > Factory Reset (model-dependent).
- Follow on-screen instructions.
- Note: This deletes apps and settings.
3. Inspect the Power Supply Components
Your Hisense TV uses internal hardware like the power board and mainboard to regulate power.
- Check Power Brick/Adapter: Some models have external power adapters. If yours does, try swapping it with a compatible one.
- Test the Power Board: If youāre comfortable opening the TV, visually inspect for bulging capacitors or burnt components.
- Voltage Check: Use a multimeter to check if the power board outputs the correct voltage (if you know how).
ā ļø Only attempt hardware inspection if youāre confident with electronics and unplug the TV before opening it.
4. Troubleshoot the Remote Control
Sometimes the remote is the culprit.
- Point the remote at a smartphone camera and press buttons.
- If you donāt see the infrared light on the camera screen, the remote may be faulty.
- Use the TVās physical buttons to power it on.
- Alternatively, try a universal remote compatible with Hisense TVs.
5. HDMI-CEC and External Devices Interference
HDMI-CEC allows connected devices (like gaming consoles) to control TV power. This can cause power issues.
- Unplug all HDMI devices.
- Turn on the TV using the power button.
- If it works, plug devices back one by one to identify the problematic device.
- You can disable HDMI-CEC in Settings > System > Control Other Devices (CEC).
6. Firmware Update and Software Fixes
Outdated or corrupt firmware may cause power issues.
- If the TV turns on, navigate to Settings > Support > System Update to check for updates.
- Use a USB drive and Hisenseās official update tool if the TV is unresponsive but supports USB updates.
7. Power Surge and Electrical Damage
If your TV stopped working after a power outage or surge, it might be damaged.
- Use a surge protector to prevent future damage.
- Consider professional repair or replacement if internal components are fried.
What If My Hisense TV Turns On But Screen Is Black?
