I have a philips 42 inch LCD TV (42FL3704D/F78). I've had it for about 2 years and came home today and could not get a picture on HDMI 1 or HDMI 2. I had a directv box plugged into HDMI 1 and a DVD player plugged into HDMI 2. I know the cables are ok since they work when I plug them into HDMI 3. Are the inputs broken? Is their a way to reset the TV?
