Follow these four simple steps to retune your TV:
- Press menu or home on your remote control
- Select set-up, installation, settings or similar (if password needed, try 1234 or 0000)
- Select first time installation (sometimes called factory reset, full retune or auto-tuning)
- If asked to delete existing channels, press OK and your retune should start automatically.
* The exact process differs between makes and models of equipment.
