Will not power on regardless of attempt recommended. There is only a white pin light on back.

HP Pavilion all in one desktop 

24-b223w 

Won't power on despite attempts made of the recommendations. The on/off button is lit up and there is a small pin light on next to where the power cord plugs into the back of the  monitor so it is getting power but screen remains black/off. Product is out of warranty now.
