HP Pavillion 27" core i5 went blank (gray) and I've tried a few things but still not working

[Sirius1208]

My monitor on my HP all in one 27" went blank and I can't get in running again.  The computer is barely one year old.  Is this a common problem?  Will I need to replace the whole computer or is there something I can do to try and fix it?  Thank you for any advice.
