mac mini 2.0 flickering screen 2015

Hi all,

New Mac user here. I also have the flickering screen issue with a brand new Mac Mini 2.0. I love it were it not for it flickering and loudly interrupt my tv viewing. HDMI connected to an LG HDTV.

All updates done. Is there a fix for this? I only found old fixes. I've tried everything a getting very frustrated. Help. Yosemite 10.10.3 Intel core I5.

Thank you, and sorry to mods if I posted in the wrong place.
