4k box blank screen when it updates/restarts

[rhealey6]

I got a 4k box yesterday and was having issues setting it up on my LG cx. The problems started when I tried to set up my remote. First, for some reason, I couldn't find the LG tv on the pairing list. I picked a random tv and then tried to repair the controller. Long story short when the box detected my tv it was on the pairing screen for almost an hour. I unplugged the box to repair the remote. Long story short I was able to pair the remote but for some reason every time the box is restarted from either and an update or from the menu/website I get a blank screen (no sound/picture). If I go through the guide and click on another channel I get a picture/sound turns on and there is a pop-up saying that went wrong. Other than that the box seems to be working just fine. I can live with this if I have to, I don't watch that much tv but it is an annoying problem that I would like to fix. Sorry for the long post and I hope I'm making sense. Long story short I get a blank picture when the box resets from either the menu or daily update and the only workaround is to change the channel. I can do a hard reset on the box and do a new setup or could this be a handshake problem with my tv? For the record, I am using the HDMI cable they gave me. Thanks again and I'm sorry for the long post!
