From Sat., Jan. 11 until sometime Mon., the 13th my Bolt had a banding problem on both live TV & recordings. The lower half of the screen had 4, approximately 4" bands showing 1/4" vertical intermittent lines of live picture and garbage. Netflix, coming in through 'smart' TV was fine.
I tried removing power for 5-10 minutes three or four times, and resetting TiVo a couple of times with no help. Monday night, I thought I could probably watch Jeopardy GOAT satisfactorily through the banding - - The picture was perfect for both live and recorded programs, and it's fine today.
