Did you look for a optical to component decoder?
My 8 year old Sony Vega died (for the second time - repaired it once 3 years ago - not doing it again). Looking at HDTV's and even bought a Vizio 42" Smart TV. Felt good until trying to connect it to my Sony home theater system (probably 10 years old). There is no component audio output jacks! Only a single headphone style output and an optical output. My home theater system only accepts component inputs... Guess I'm taking this back. Looking online, I am noticing most new HDTV's don't have these jacks anymore. Am I out of luck? Help! Thanks!
