    well there could be a few issues.

    1. does the LCD display any messages or monitor menu's... if so, then the input option on the LCD is set wrong or, your pc has video card problems

    2. ifi the LCD display does NOT display any menu or anything... then there would be an issue from your LCD... either take it to a tech, or replace it.

    thats all i can think of for now... Hope this helps
