Is this any help to you???

Certain older Zenith TV's have a problem working with video game systems. The 
following information is for the SF5749W model.  To access the service menus, 
press and hold the menu button, then the volume and channel, so all three are 
held at the same time.  The regular controls search through the menus, and 
select and adjust change them, with enter to confirm a change.  On menu 1 is 
a "vforced" option which might be necessary to get VCR menus--or games--to 
work....
