I need some advice. I bought a 32 inch Insignia Hd TV and hooked it up to a Dish 622 receiver. I first jacked it into component. Worked great until it turned the TV off. When I turned the TV back on the sound does not work, so I have to push input and pick another source and then push input again to get the sound back. I then went and bought HDMI cord. Worked great until I turned the TV off. When I turned the TV back on the picture is badly compressed. So, I have to hit input and choose composite. Hit input again and select HDMI to fix the problem every time I turn the TV on. Does anyone know what the problem could be? Thanks
