Issue with Official HDMI cable

I had this poblem on my Bravia television after going to the sony centre where they are meant to be experts on their own televisions the man and engineer claimed they had never heard of this problem (what a joke its one of the most FAQ's on the net)
so we bought a new official HDMI cable with gold plated connectors (What a waste of £30) we still had this problem even using the red white yellow leads didnt fix the problem either.

so we called a company that deals in repairing projection televisions and yes this is a common fault with he playstation 3 it knocks off the factory settings we hd the engineer for a small call out fee no tools or taking the television away was required but a code entered to reset the telvision to its origianl factory settings its like new again.
