Tachchen,
du kansnt das One Button Reset (OBR) probieren:
1. Power off the TV set by disconnecting it from mains
2. Press the joystick to the DOWN position and hold it
3. Power on the TV set while still holding the joystick in DOWN position
4. Wait for the LED blink procedure to kick in (LED will blink in fast succession for a few seconds) or for the TV set to boot up
5. Let go of the joystick
6. The TV will now reboot and will trigger the virgin mode again
