How do I remove a green KTC AT or keypad test box from a TV corner?
Answer
A green KTC AT or KEYPADTEST overlay usually means the TV is in a factory, hotel, or service test mode. Power-cycling the TV and switching from Retail/Demo or factory menus back to Home mode typically clears it.
Before you start: stop right away if…
- If the overlay persists after Home mode and a power cycle, stop repeated button experiments and contact the manufacturer or a technician.
Follow these steps
Exit the keypad or factory test screen
Press Exit, Back, or Menu on the remote. If that fails, use the TV’s physical buttons to leave any KEYPADTEST or factory overlay.
You should see: The green box disappears, or it remains after leaving visible menus.
Switch from Retail or Demo mode to Home mode
Open Settings and look under General, System Manager, or Retail/Demo Mode. Set the TV to Home Mode if it is currently in retail or store demo mode.
You should see: The TV stays in Home mode after a restart.
Power-cycle the TV
Turn the TV off, unplug it for at least 60 seconds, plug it back in, and turn it on.
You should see: The overlay is gone after startup.
Check the input source
Press Source or Input and select the correct HDMI or live TV input. Confirm the corner text does not return on that input.
You should see: The selected input shows a normal picture without the green service box.

Extra tips
What to look for: A green on-screen box reading KTC AT, KEYPADTEST, BUTTON PASS, or similar factory text in a corner
Before you change anything: Note the exact overlay text. Try the TV’s own buttons if the remote cannot dismiss it. Avoid random service-menu codes from unofficial sites. Unplug the TV before holding buttons for long resets if the manual recommends it.
