pixelation

My setup Cable box - to an hdmi 4 port switch - to hdmi connection on tv. My tv is starting to show what appears to look like like hues/blotches and pixelation. it is very noticible on any shade of red and skin tones. If I go into the service screen and run the test screens they all look good...

i am have a problem after my tv is on like four min it will get little lines starting a top and and gets worse as it warms up... anyone experience this and or have any ideas how to correct it

Okay, I'll admit that it's a cheaper player, I bought it for the HDMI connection for under 50 bucks. It's a Philips DVP3962/37. It's strange really. I have played a few movies on it since getting an HDMI cable ( 6ft length ) without issue. I tried one of my Star Wars DVD's the other day...
