My HDTV (Panasonic PT-53WXD63) has a built in tuner and I have a question. Obviously, with these sets one does not need an external set-top box and expensive component, dvi, firewire, etc... cables to transfer the decoded digital channels to the display. I am curious how this connection is actually made internally with built in ATSC tuners. It would seem the quality could be better with one less cable/connection. Would the tuner portion typically be on the same circuit board as the display portion with these sets? If not, do you think the manufacturer cheaply does the internal connection or is it comparable to a reasonable component connection?
