Does anybody know how to get into the service menu on this tv? I googled for rca service menu and I found one that said hold down the menu button, press and relase power, press and relase volume +, and then release menu. I'm getting some weird geomettry problems when I'm starting mamewah and mame. The left side kind of bows out at the bottom and the right top corner bends in. I have a sharp 27" in my cabinet which looks great. So I don't think its a video card or cable issue.
