Hi, sam! It will depend if the TV supports either the composite or component connection. You may refer to this link for more information: https://www.sony-asia.com/microsite/bravia_connectivityguide/bdp/index.html ~Ralph
Unfortunately, using an HDMI-to-RCA cable will not work. If your Vankyo projector supports RCA input, we would suggest connecting the DVD player to the projector using an RCA-to-RCA type cable. -Sam
