Am I alone in this? My Bolt is 6 months old and has worked just fine. Bad news is that it ceased to be able to receive any of the main channels (2 thro' 11 - thats CBS, NBC PBS etc) since 9/2/16. I only use antenna input. I have no cable. There is no signal showing in 'live TV' mode. For example for channel 7-1 my Bolt is 'looking' at KUEDDT. However if I use the 'antenna signal strength' feature there is no digital signal on that channel - the digital signal for channel 7-1 is on KUED-HD. While in antenna signal strength mode - I can see a 'perfect' image on KUED-HD . Many hours spent with phone support and on-line chat. Last night they agreed to exchange my Bolt. Best-Buy gave me the exchange unit this morning (thank-you!). IT HAS THE SAME PROBLEM. I do not know if the transmission specification has changed or whether Bolt has changed. My 3 tv's can all receive these local antenna channels perfectly. Bolt cannot. My system is dead.
