Welcome and thank you for considering the SONY Community!
Thank you for your post. You can check the line-up of the Blu-ray players that we have at https://www.sony.com/electronics/blu-ray-dvd-players/t. However, we do not recommend to mount the unit behind the TV vertically since our players are all tray typed and not a slot-load machine. There is a possibility that it may damage and affect the playback operation.
