Converting Sony CRT to flat screen TV

Been shopping today for flat screen to replace the old girl (1996 vintage Sony CRT TV). In my MH the theater sound system was original equipment and the Sony TV, I'm told, used a variable audio out jack which allowed the TV volume to raise/lower the theater sound system with the TV remote. When the theater sound was turned off (via a dash switch) the TV's own speakers were used. So, if you look at the back of the Sony CRT TV there are three connections, Coax for cable in, 110 VAC power, and a audio out jack which resembles a RCA connector but has a two conductor cable.

My question is this; you folks that have made this change from Sony CRT to flat screen, have you sacrificed the surround sound (theater sound) system capability and are using only the TV speakers or is there an adapter available to get the variable audio out feature neccessary to use the theater sound system? Also does the flat screen need HDMI, Optical output or something else to feed an adapter?

Hope this is clear and if seeing the audio out jack would help in some way, I suppose I could figure out how to post a picture.

Thanks for any help.

    My CRT never offered the Surround less I ran it via the VCR.. And today with Flat Screen I only use the Home Theater system for special programming like a PBS concdert special. and I run those through the DVR.

    Many of the better flat screens have both analog audio out (L/R) and optical.. Surround depends on the broadcaster with optical (TO/S Link) out.

    What does TOSlink stand for? Tosahiba/Sony link.. yup that's who came up with it. And a common data format on TO/s Link is SPdif (Sony Phillips Digital Interchange Format) Been doing this stuff a long, long time (1990s at least)
  • Flat panels should have a variable audio out, perhaps with RCA connections. There's also likely an optical audio out. That's the best one. I'd be sure to look for that. Cheaper sets maybe not.

    I'm using the headphone jack and a set of computer speakers. The speakers in newer TVs are pretty bad.
  • If you plan on watching digital and HD programming then HDMI is the way to go. It carries audio and video. Sadly other than using 2ch stereo analog outputs your legacy HT system will not be supported.
