I was watching TV last night and the picture and sound on the TV went black. Rebooted and it was fine for about 10 minutes then went out again. Further reboots, HDMI cable replacement, and switching HDMI ports on the TV were unsuccessful. The mini stopped working, but after a reboot worked fine. Both Tivo online and the Android app also find the Bolt and I can watch live TV and recordings. Am I correct in assuming that the HDMI port on the Bolt is dead?
