I mean no offense here -- You need to read the front plate of your combo very carefully. You wrote that it's a "vcr and dvd combo". What you need to transfer home VHS movies to DVDs is a video player or player-recorder, and a DVD recorder. For $200 that should be what you have, but what does it actually say?
If you have a DVD recorder, then the problem may be with getting the cables on the back set up so the video tape output goes in to the DVD recorder. Then the DVD output goes to the television. These connections may be co-axial cable or a set of 3 cables with color-coded plugs.
If you do not have a DVD recorder, well, this combo is never going to do what you want.
Because the manuals that come with this equipment are usually translated through several languages (Chinese to Korean to Senegalese to Hindi, etc) before it approximates American English we have trouble figuring out how to use the gear. Sometimes studying the drawings of ways to hook up the cables (without getting too hung up in the associated written instructions) will help.
Be well, be safe,
