When pressing the power button. The timer light on the TV turns on then off. You can hear the TV powering up. The lamp is lite in back, but no picture. The lamp then turns off and the standby/temp light and lamp light blink simultaneously. We tried to reset the lamp timer, no changes. Any help would be appreciated. Thank you. Samsung HL-T5075S
@union422 “the standby/temp light and lamp light blink simultaneously.” is indicating that the lamp cover on rear of the set is not properly shut. Check the microswitch to make sure it closes properly.
