Make sure the battery or batteries are either fully charged or are new. If it still will not work, then the camera needs repair, and it may be better to sell it then for parts or repair, as is on a site such as Ebay.

Normal batteries it's not working for me!
After i replace standard alkalines with rechargeable NiMH batteries Sony and Varta 2700 Ni-MH it's was working!
My camera it's turn on every time!
