1. When the rear cover is opened A sensor detects when the rear cover is opened and turns the set off and then into Standby mode. If you close the cover or fix the switch, you can turn the set on by pressing the Power button on the unit or the remote control. The set will then operate normally. 2. When the temperature sensor operates When the set is overheated, the internal temperature sensor turns the set off and the set goes to Standby mode. When the internal temperature of the set returns to a normal range(95�), turn the power on by pressing the Power button on the unit or the remote control. The set will then operate normally. 3. Attempting to turn the lamp on fails repeatedly If turning the lamp on fails, the set automatically tries turning the lamp on 3 times. If all attempts fail, all LED's on the front panel will blink. Check the lamp and the ballast and replace them, if necessary. Samsung Electronics 6-7
