Sony handycam does not play back well on TV

I have a CCD-TRV37 sony Handycam camcorder that uses 8 tapes.the camra records fine and plays back fine on the attached LCD screen, but when I hook it to the TV to playback the picture comes scrumbled and not clear, audio however is fine. I used different  V/A cables with no change. it does not have S video out put, put there is an output marked RFU DC out. could this be a programing problem in the camra, or is it a bad output. I have many tapes that I want to play back and record on DVDs. Any advice on how to salvage them. Thanks
