Hitachi Ultravision 42HDS52 42-Inch Plasma HDTV
Buyer Beware!!
The monitor out jacks on this TV do not output audio signals when the video inputs are high quality (HDMI or component video).  Therefore you must buy an additional audio receiver to use external speakers with this TV, if you want HDTV.  This is not explained in their product literature, nor is it well known by their distributors.  This info appears near the end of their trouble shooting guide, so beware this will be a shock if you're used to hooking up standard TVs.
