HDMI issue

I have a Raspberry Pi 3 running Libreelec. When I switch the source on my TV from the port that the Pi is connected and back, I get no video(dim backlight). The TV does not have a No Signal message that displays when there is no signal. I also have a DVD, Roku and tuner connected to other HDMI ports which are not displaying this behavior. I have turned off the CEC on the PI and the equivalent on the TV.
Could someone assist me troubleshoot this issue?
