      There could be several reasons for picture issues with your Sony DVD Player. First, the connecting cords might be damaged, so try reconnecting them securely. Check the connection to your TV and switch the input selector so that the signal from the player appears on the TV screen. If the picture output from your player goes through your VCR to get to your TV, try connecting your player to your TV’s S VIDEO input. Also, if your TV cannot accept the progressive signal, select “NORMAL (INTERLACE)” so that the PROGRESSIVE indicator turns off.
