I found what looks like a card reader and an headphone input on the back of my t.v. (Toshiba REGZA 26HL47)by the power-cord and it was covered up by the manufacture... i was wondering if i up-grade the firmware would i be able to use them, and if not then why were they even put there?

Miner modification design adjustment for a mass products productions fixes.99% of the LCD or plasma tvs out in sale for the consumers in the markets are never have to be upgraded or reinstall main frame firmware software at all,if u don't mess around in the main tv Tuner signal bard all.The main frame firmware software are alway and never suppose to be mess around for the tv entire life time anyway.
