Teac Manufacturing

How do I get in to the manufactures hidden menu for TV TEAC CT-M807SV? So I can adjust the horizontal and E/W.
For the record I am an electronic technician but haven’t worked in my field for about 10 years. The TV became this way after my one year old baby was playing with the remote, I checked TV its ok, but because I don’t have the schematics it’s harder diagnose. A friend of mine thinks I could fix it if I can get in to the manufactures menu.
Thanks for all the help…
Hell, Even I DON’T know who makes TEAC TVs…..
They were BIG in tape recording equipment…
Whose chassis do you think it is? Hitachi? Samsung? Toshiba? Sanyo?
