Steps to fix Hisense Roku Tv Not Turning On

Here are troubleshooting Steps to fix Hisense Roku TV not Turning On:

1. Power Cycle the TV

The most simple and quick method to fix Roku tv not turning on is to power cycle the TV. Power cycle TV by unplugging it from the power outlet for 60 seconds. This allows capacitors to discharge completely.

Then, hold down the power button on the TV itself for 30 seconds to drain any residual charge. Finally, plug it back into the outlet and try turning it on as normal.

Check remote control by replacing old batteries with new ones. Low battery power can prevent proper remote function.

Also, reset remote by holding down the power button for 30 seconds. This clears any synchronization issues between the remote and TV. Try using the manual power button on the TV itself if the remote still fails to turn on the set.

2: Check Input source

Press Input or Source button on your TV remote and cycle through each option like HDMI 1, HDMI 2, AV, VGA, etc.

Ensure the correct input that matches your video source device like a cable box or game console is selected. The TV may have switched to a different input that has no video signal.

If cycling through inputs fails, try connecting devices to alternative ports or using different cables to test the equipment.

3: Check Cable Cables

Check power cord and each HDMI cable connecting devices to your TV. Check for any damage like fraying, bent pins, or loose connectors that could interrupt vital power and video signals.

If cables check out, try swapping them with spare functioning HDMI cords to determine if the issue is a faulty cable. Also check HDMI ports for dust buildup or damage causing poor connectivity.

4: check power supply

Test if problem originates from the AC outlet or internal home electrical issue by plugging the TV into a different nearby power source.

Also check the fuse box to confirm the circuits are functional and dispense proper current. Use a multimeter or test light probe if available to double check for live voltage inside the outlet itself.

5: Test for Faulty Backlight

To diagnose a failed LED backlight system, turn off ambient room lights and shine a flashlight at the screen while powering on the TV. If a faint picture is visible, this indicates the display panel is likely working but the backlight array responsible for overall illumination has malfunctioned.

6: Try Reconnecting HDMI

Reseat firmly inserted HDMI cables on both ends, swap for an alternate working HDMI cable.

Change connected port used, or try a different device input type like component or RCA.

This will determine if the issue stems from a loose HDMI connection, faulty cable, problem input or general device compatibility.

7: Factory Reset

Return TV settings to factory default by locating small pinhole reset button on the back panel, outlined in the instruction manual.

Hold for 5-10 seconds until confirmation the reset is complete. This erases all personal data, apps and customizations, reinstalling the TV’s original programming.

8: Test Hardware Issue

If powering, backlight and video signal connections test functional, internal component failure like the LED driver, T-Con board or internal ribbon cables may be preventing the TV from fully powering on. Go for professional TV technician assistance.

9: Support and Warranty Lifeline

Locate TV model and serial number generally printed on a label on rear housing to reference when contacting Hisense Customer Support online or via phone. Purchase date and retailer details may also be required for warranty claims or guarantee eligibility.

10: Keep It Offline

Consider switching internet connectivity off if the TV routinely receives firmware updates that seem to create new technical problems or bugs that weren’t previously present. Unplug ethernet and disable Wi-Fi in the settings menu to prevent such issues.
