Roku Express 4k+ gets "No Signal" from old Vizio TV when opening Apps
Just purchased 3 Roku Express 4K+. 2 of the 3 work great. The other is getting a "no signal" message on an older VIZIO TV when I open any app. It will open the app and get to the " this seems to be taking longer than normal" message and then go to the TV "No Signal" and bounce back to the bouncing ROKU graphic. I have reset, unplugged the TV and Roku player. Moved the power cable from the USB port on the TV to a receptacle. Changed the HDMI cable. If I unplug the power strip everything is plugged in to, it will work until I turn it off. The ROKU player blue light stays on constantly on this one unit, even when it is powered down. The 2 that work fine go dark when powered off. Is that telling me something I don't know? I have moved this player to where the other players are working and it does the same there. Also have an excellent WIFI connection. Seems like it may just be a faulty player. ???
