How do I access the service menu on my Zenith D36D53? (1 Viewer)

[Josh Q S]

I have a 36" HDTV/Monitor Zenith (D36D53) and I'd like to tweak some of the settings (I'm getting MAJOR overscan). Anyone know the codes, or maybe a place to find them?

Thanks for any help!

Anybody? I have some major overscan/offset image problems that need to be fixed asap! Any information would be greatly appreciated!
