MASTER RESET (will return all settings to factory presets)
If the Power off - reset does not solve the problem, you may have to
perform a master reset by disconnecting the power supply, and then
while reconnecting the power cable you will have to press the [PWR]
and [CLR] keys at the same time, and hold both keys depressed until
a picture appears on the screen. All user-made data will be erased,
and all settings are returned to factory presets.
