I have a WD TV Live Hub for almost a year. It’s been working fine. Recently it gives black screen when it was turned on. After a hard reboot (press power button for 5 sec), it will be ok. I am not sure when it started or after which update because I do not watch it very often. It’s like this for more than two weeks now. I have updated to lastest version firmware.
I have Onkyo 608 receiver connects Hub and Panasonic PJ all through HDMI. I also have Panasonic BD player and Dish HD receiver connected to same Onkyo via HDMI. It’s been like this for a long time. Everything works fine till now.
