Welcome to the forums, Newcomer. First, click on the link in my signature. Work through the checklist of common areas to address for "no boot" / "no display" concerns. Note that at the end of the list, there is a link to jsc's breadboarding guide. Should the standard checklist be unhelpful, consider using the breadboarding guide to rule out case shorts.
If after consulting both guides, you still have the problem, post back with any new observations. Good luck.
