Try Googling it there should be many manuals for all types of TV or Hifi available there. However most will be in PDF form so you will need acrobat reader installed on your PC go here

Go to google and type in manual sanyo Exact Make
So for arguments sake manual sanyo s234-67 obviously dont put this number in but your own model. If nothing comes up just jumble the words around? Fail that go to ebay and see if you can find your exact make of TV there and send an email to the owner if they would be prepared to photocopy the portion you need and pay them a small fee for their trouble Most will do this? You don't ask you don't get.
Hope this helps
