Push on power button. Power light turns on green, flashes a few times. Then the power light turns red and flashes in a sequence of 3 blinks, which repeats over and again. We replaced the projection lamp, still same. We did power reset, still same. We ensured lamp door cover securely in place, still same. We spray dusted the area, still same. Sometimes the TV WILL turn on if my husband fiddles with the lamp door, and we go through the Setup Menu – Lamp Replacement process. Then the TV will stay on for about 1 to 2″, and blink out again. Any suggestions or help would be much appreciated. Thanks.
