- Physical TV chassis buttons function while remote control produces no action.
Root Causes
- Depleted battery voltage or poor battery spring terminal contact.

Step-by-Step Diagnostic & Repair Steps
Ask Technician via WhatsApp- Smartphone Camera IR Test: Open the camera app on your phone, point the front tip of the remote at the camera lens, and press buttons. If a purple flashing light is visible on the phone screen, the IR transmitter is functioning.
- Re-pair Bluetooth Remote: Press and hold the Home + Back (or Guide + Menu) buttons simultaneously for 5–10 seconds while holding the remote 10 inches from the TV until pairing confirmation appears.
- Reset Remote Control: Remove batteries, press every button on the remote once to drain internal capacitive charge, insert new alkaline batteries, and test.
- Clear Bluetooth System Cache: Open Settings > Apps > System Apps > Bluetooth > Clear Data & Cache, then reboot TV.
- Mobile Virtual Remote Fallback: Download the Google TV app on your smartphone to navigate the interface while troubleshooting physical hardware.
When is Firmware Flashing Required?
If remote functionality fails following an update due to corrupted Bluetooth pairing databases or altered IR protocol tables, flashing matching vendor firmware restores the native remote profile.
