I updated the software after a prompt saying 1 was available and the TV just went to a completely black screen and won't turn off at all. I've tried everything and i'm getting very frustrated. Nothing responds from the remote, the light blinks when i press buttons (but not when i press on/off button). This is the 2nd time in 8 months that i have had a bust TV and it was brand spanking new when purchased them 8 months ago. Sony is terrible for customer service when things go wrong which is annoying because i have always supported them and purchased Sony products when available. Live chat help is needed, i'm left in limbo now and my TV is still under warranty
