Trikos, trying hitting the following buttons on the VPL-HS51 remote . MENU, MENU, ENTER, ENTER, ARROW LEFT, ARROW LEFT, ENTER . This might enable you to get into the factory menus for tweaking . I have the HS 20 and it works on it . I have not had the chance to try it on the HS51 yet though . Check it out it can't hurt to try .
