the last things to try, if you didn't alread tried:
Uninstall Intel drivers and check if HDMI playback is still here and check if it works
Uninstall nvidia drivers and check if HDMI playback is still here and check if it works
it must some drivers issue but without the notebook in hands, it's very difficult to narrow the issue.

please report the correct model number, E?-571G and installed OS.
if HDMI out is used by nVdia card, you can do a quick check on windows services:
windows key logo + r
type
services.msc
check if NVIDIA Display Driver Service is started (double click on it), if not start it manually and set it to automati start
then check again if HDMI is still greyed

have you re-installed both Intel and nvidia VGA drivers?
when you connect to the TV, if you go to the nVidia control panel, are you able to see the TV connected?

Appear TV in settings,i can adjust resolution and everything for video,but the sound is on notebook speakers.....
