Television is an unquestionable source of happiness for the average American household, but long-term use of electrical devices always results in minor issues. If your Hisense TV doesn't turn on, rest assured that you are far from alone.
This post aims to soothe your anxieties by providing you with four tried-and-true solutions for the issue of Hisense Roku TV not turning on. If you feel that your Hisense television's inability to power is software-related, this page also includes instructions for resetting the gadget.
Fix #1: No indicator light when the Hisense TV is switched on
If the Hisense TV is switched on, but neither the indicator lights nor the display comes on, there are two possible causes:
- The power supply of the Hisense television is improperly connected, causing the television to malfunction and be unable to switch on.
- The power board of the Hisense TV is defective, which affects many circuits.
If a power connection is a reason why your Hisense television won't come on, check:
- if the power plug is securely placed into the socket,
- whether the socket is short-circuited, and
- whether the power button is cracked or has poor contact.
However, if the power board or a short circuit is the cause of your Hisense TV not turning on, you may need to contact Hisense TV's after-sales customer support to inspect and repair the TV's circuit board or short-circuit fuse.
Fix #2: The indication light is on, but the Hisense TV won't turn on
If the indicator light of the Hisense television is on, but the television won't turn on, it may be in standby mode.
To remedy this, click the "standby" button on the remote control to reactivate the television and restore regular operation.
If the Hisense TV is not in sleep mode, the inability to switch on despite the indicator lighting up may be due to a hardware malfunction.
It is advised to determine if a power module, high-voltage board, display screen, or cable is defective. You can also determine if additional circuits are open or short-circuited.
There is also the potential that the TV's remote control is defective, resulting in the Hisense television not turning on when the indicator light is on.
In this case, replace the remote and try again. If the problem persists, call a TV repairer.
Fix #3: There is a startup sound, but the Hisense TV is not turning on
If there is a sound when the Hisense television is switched on, but it still won't turn on, you should investigate if the power supply for the screen light tube is defective and causing the issue.
First, determine if the power supply delivers 12V for the high-voltage board's power supply. If not, ensure that the TV's L503 power supply is functioning normally.
Whether the voltage of L503 is normal or not, you should replace the new booster board and evaluate the situation to see if it solves the problem. The screen is broken if the Hisense TV still won't turn on.
Fix #4: Reset Hisense TV
Since the Hisense TV won't turn on, you may return it to factory settings by pressing the 'Reset' button on the back of the TV.
To access this:
- Press the power button at the bottom of the Hisense TV to turn it on.
- Find the pinhole for the reset button on the back of your TV.
- Press and hold the reset button for 20 seconds using a paperclip, toothpick, or pen.
- Press the button repeatedly until the television restarts.
- Once the television is restarted, the factory default settings will be restored.
If the Hisense TV still doesn't turn on after attempting the above troubleshooting steps, the problem might be beyond you.
In most cases, a non-responsive Hisense TV is attributed to a hardware problem, such as the failure of the main board switch circuit, the screen cable, or the screen itself.
It is preferable to call a specialist who will evaluate the television thoroughly and provide a diagnosis.
If covered by warranty, it is advised that you seek repairs from an authorized Hisense after-sales service.
