Laptop wont come on screen on the television using a hdmi port from a macbook retina

[seikogold]

Recently I bought my macbook with retina display and when I plugged it into the television with using the HDMi cord it worked perfectly fine with the image on the television. But now I when I plug it in to the television it comes up with a black screen and a white mouse. Before this incident I was mucking up with the setting of the mac book and I dont know what I did wrong. Can someone tell me how to fix this ?

Have you tried rebooting, resetting SMC and several re-plugs of the hdmi cable? Also restarting TV might help.

Got this problem also once but it was gone very quick by unplugging several times, restarting and so on.

Have you checked the display settings? I don't have the option at the moment to give you details (you can definitely find it in other threads -- I've done so myself) but it sounds like your TV is being used as a second display instead of mirroring.
