IF power light comes on and a few seconds later goes off, do the self check this model has.

On front of set when this happens, press and hold both the menu and input (device) buttons at the same time for at least 5 seconds and then release both buttons.

Watch the power light closely, it should blink a two digit error code like; 2 blinks, 2 blinks, a pause and then repeat it several times.

Let me know what error code you find and I will tell you what it means.
