Wow, that is a most unique hardware failure. The color bands are getting filtered on each copy. It is like its an analog signal. Call Sony to get it repaired.

Thanks for your reply, Sony will charge a lot of money, so i prefer to fix myself if possible. Someone told me, this issue can come from the lcd controller chips who is on the motherboard, i dont have the skill to change that chips... so in last solution i plan to buy an extrernal lcd board controller to by-pass the motherboard one, i will plug it on the hdmi port.
