I'd say don't waste your time fixing it.  Most likely, you don't want to 
use an S-Video cable on the 57" TV because S-Video limits you to NTSC 
(and NTSC is almost 52-year-old technology--it turns 52 on Dec 17).  
Instead, get a more appropriate cable (VGA/DVI, depending on your TV) 
and a good modeline and never look back.  Assuming it's a 57" 720p TV, 
set it up with 1280x720 pixels.  If it's a 57" 1080p TV, set it up with 
1920x1080 pixels.
