What is your setup in the Main menu > Parameter > System > A/V?
May be fix the Mode and refresh rate.
There is also an option to bypass the HDMI EDID check.
You probably need to switch your user experience into expert mode to see all the possible options.
Thanks I have sorted it out.
In the av settings I have set the mode to a different resolution, set the refresh rate also to a different one instead of auto and checked the edid.
