Component Video In Upgrade Possible?

GOOD QUESTION, Mi3491.I HAVE A 70" ULTRAVISION SBX MODEL AND I HAVE THE SAME PROBLEM. WHY DID THEY MAKE SUCH A GREAT TV AND STOP SHORT OF ONE ITEM THAT IS SO IMPORTANT?

This is only a repeat of what my ISF guy told me.You would almost have to tear the set apart.Component input by passes the NTSC decoder,and has to be done from the ground up.I am in the same boat; Pioneer Elite pro 119 We just bought our sets to early. HDTV is the way to go.The sets are cheaper than the 6 grand I spent. Read the review on the 61 in Sony kp61hs10 37 hundred.The Perfect Vision #31 Jul/Aug.
