It has a headphone jack input for audio.
Yes......it has the standard 3 pin RCA jacks (red, white, yellow) for older DVD players and VCRs. Most of the newer DVD players and Blue Ray units have HDMI.
There are several different inputs on this television including and AV connection. Make sure that when connecting those devices that they are connected into the correct ports and that you are using the correct cables.
Yes... I have the Bose Solo connected - excellent!
Yes it has one set of three red, white , yellow rca type. And 1 set of the newer 4 color rca for HD players.
My old VHS/DVD Magnavox player attached to the Red,White,Yellow (hdmi) in the back of the TV and when I want to play it, I select "AV" from the on-screen "choice boxes" and it shows the DVD or Video. If your old dvd player doesn't have red, white, or yellow lines, then I guess the answer is no.
Yes, one set of A/V inputs (YRW). One set of audio RCA jack outputs.
Yes it does, one video component which it's yellow red and white and it has one composite for a better resolution one audio input, I hope this helps your question
