I’m still a “newbie” so, sorry if this was covered elsewhere. I actually did a search but found nothing.
My Tablo is the Quad 4 OTA DVR and I’m currently on free trial for the premium guide.
My guide seems to work but I have an ION channel that shows up on the list (left column) but no content is shown - just a bunch of “zebra stripes”. In my case it’s channel 43 out of Kalamazoo/Battle Creek MI.
I’ve rescanned and refreshed my system many times during the installation procedure.
I live in a two zip code city about 8 miles long north to south. For years I used my zip code without issue. Then one day like you my guide/live TV was all messed up. I tried everything I could think of and nothing would fix it. I then found on the forum to try another zip code. So I changed it to the south side code and it fixed everything, back to normal. Not sure why this happens and I never changed it back to my “north side” code.
