Sony forum: Sony Bravia KDL40VE5 Sound and video Issues

I have had my Sony Bravia LCD for almost 2 years. After about 6 months it started having some sound issues. At random times when I turn the TV on or switch from HDMI 1 to HDMI 2 it will go mute. It never goes out while I am watching TV. I thought it could be one of two things. Either the HDMI cable was faulty, or one of the HDMI ports was not working properly. I have tried putting cables in different ports and bought a new cable but it still happens. The only way I know how to fix it is to either switch the input back and forth (from HDMI 1 to HDMI 2) or just turn the TV off then on.

I would like to know if anyone has had this problem and if so what did they do to fix it. I have called Sony about this and all they will do is send someone to look at it and at best they will give me a refurbished one. The problem with that is that I can't make it happen when I want. Everyone knows that if the repair guy was here for a month it would never do it. But, as soon as he leave it messes up.

Thanks for your help.
