Setting up Chromecast on Samsung 43 Inch PLASMA HD Ready TV (43H4100)

When I try to set up my Chromecast 3 on my TV, there is a split second when “Chromecast” is displayed and later turns to a flickery green screen and then a black screen stating that there are no input sources. This is noticed in both the HDMI ports. I’ve tried rebooting the Chromecast and also switching on and off my TV. Is there any fix to this? The Chromecast works well on my monitor. This is what I get!
