Black/Blue screen on startup
I have an 2011 Mac running 10.12.6. The Mac turns on but is displaying a black/blueish tint. There is no icons or cursor. Upon turning it on, I do hear the startup chime and DVD player so I know there is power to internal parts. I do feel the fan blowing through the vents. Nothing appears on the screen. None of the USB ports are working and thunderbolt port is not working either. If I remove the RAM, the computer does recognize there is not memory.
The Mac was working before and it was plugged into a power strip. So, I don't know if something got zapped. Other users thought it was the video or inverter card that is bad.
