HDMI display not working

Hey Guys,
So after 5-6 years I finally wanted to play games on my PS3 but the HDMI display out is not working. I did try with the Component cable as well and it does give a display on that but it flickers a lot, the display is washed out. Does anyone know whats wrong with my PS and how can it be fixed. I want to connect it with my pc display which only supports HDMI.

Thanks!!
