widescreen flat TV

Why is the picture in Philips TV is displayed in red and green or the color red is missing when the TV is connected to an accessory device through component cables

Why is there no sound coming from my Philips TV after I connected a Philips DVD player via HDMI?

How do I switch to the AV inputs on my Philips TV to watch an accessory device (DVD player, Game System, VCR, etc)?

The picture is stretched out and/or the image is short and fat and/or there are black bars on the side or on top and bottom of the picture in my Philips TV
