I have had an Xbox 360 connected to my Sony VGC-RT150Y by way of HDMI input on the back. In order to switch to this input, you have to press the HDMI select button on the right hand side to do so. I have been able to do this fine for the last 4+ months since i bought it. A couple days ago, I went to play, and when I pressed the same HDMI select button, nothing happened. Usually the button will glow green and change displays to the HDMI input. Nothing is wrong in the Device Manager, I ran every virus/malware program (nothing), even did a system restore. Nothing out of the ordinary has happened from when it last worked until now. Sony Customer Service is a joke and I’m not really sure what could be wrong. Any help would be greatly appreciated.
