Tv powering up with light then backlights turn off instantly

Hi all, I currently have a hitachi 55HK25T74U and I am experiencing some issues. When I turn the tv on I can hear it starting up, the screen has a quick flash then goes back to black. I can see that the backlights turn off right away and the hitachi logo is slightly visible when I shine a torch into the screen.
