  7. Defective power outlet.
  8. Loose or faulty wiring connections.
  9. Short circuit or ground faults.
  10. Incorrect fuse selection.
  11. Power board charging high power.


To address issues with blown capacitors, follow these steps:
  1. Remove the back cover of your Hisense TV and inspect the capacitors on the power supply board.
  2. Replace any capacitors that appear doomed or swollen immediately.
Additionally, consider the following actions:
  • Ensure that your TV capacitors are not receiving high electrostatic charges.
  • Replace any faulty power outlets and wiring connections.
  • Avoid operating your TV during power surges or outages.
  • Prevent TV overheating by limiting prolonged usage.
  • Avoid plugging multiple appliances into a single circuit board to prevent overloading.
  • Install a voltage stabilizer to minimize high-frequency variations, short circuits, and power surges.
  • During the installation of new capacitors, select the appropriate fuse.
  • Verify that your TV’s power board is charging the required power.

By following these troubleshooting steps, you can resolve the issue of your Hisense Tv won’t Turn On Red Light Flashes 7 Times. Remember to exercise caution and consider seeking professional assistance if needed.
