Yes, if your TV has the A/V input, then it should work fine! The connections you would be looking for will be 1x red, 1x white, and 1x yellow. If the DVD combo unit has component output, and the TV has component input (Red, green, blue) that will connect fine too, but you will not get any sound through the tv.
Let us know what colours the connections on the back of your TV are.
Better still, take a picture of the back of the TV and the DVD combo unit, and post the link here.
