Had a weird issue with my replacement P75 a couple days ago:
Had been watching Dish Network for a bit, and decided to cast Star Trek: Beyond via Vudu.
Opened up the Vudu app on the Tablet, but there was no Cast icon available. Tried all the other cast-enabled apps, and none of them would cast.
Rebooted the Tablet, but the issue continued. Powered the display off and back on which still did not resolve the issue.
I could change settings on the display with the Tablet, just couldn't cast.
Restarted the display a second time, and when I did, there was a BLACK VERTICAL LINE, about two inches wide, with soft edges, running the full length of the display, a few inches from the right side. (This is when I started to panic).
Powered the display off a third time, and with the restart, everything seemed normal. (Whew)...
Casting was back, so we watched Star Trek: Beyondv (DV version). It seemed very dark though. I had to crank the backlight.
Anyone else had issues with a black band running down their P series?
