Suddenly my Sony NSX-32GT1 will no longer show live tv. It is just a black screen, but I still have audio. The same things happens with all the inputs. For example my blu ray player connected via HDMI has a black screen with just audio also. Everything else works as always. I can stream netflix full screen no problem, browse the web with chrome, etc. Any suggestions on what to do? I have done a reset about 3 times. I also unplugged it for a long time, just to see if that would help. I find it odd that all the apps work just fine, anythings that is built into the tv is working. Everything that plugs into the tv has a black screen, with audio only. Thanks.
