If you are experiencing the issue where your LED/LCD TV goes blank for few seconds every now and then, then the culprit is probably your HDMI to HDMI TV cable. The one you have may not have proper shielding which does not protect it when any voltage fluctuation occurs or when a tube light is switched on. The fluctuation is passed to your TV and so it blinks or goes blank/black for few seconds. The solution is simply to install a high-quality HDMI to HDMI cable.
