Hi there - I have a strange issue with my Panasonic TH-55CS610A that I just cannot resolve. I have used a chromecast in this TV for a couple of years without issue. The chromecast was removed for a few days and put back in but has not worked since......it seems to connect and any device shows it as casting yet no vision. The chromecast works in other TVs and I have tried the HDMI ports and video can be streamed from a laptop no problem. I then bought a new chromecast and exactly same problem......factory reset the tv and still same problem. Any idea how to fix??
