Display is white and the machine reboots continously

Hello everybody.

My machine, an iMac (27-inch, Mid 2011) gave me a black screen yesterday, out of the blue, and after I rebooted it it starts the boot process with the Apple horizontal bar but at the mid point it goes blank as in the two pictures below.

Anybody has any ideas before I bring to service next week, please?

Your system is getting stuck within POST. Let’s see if we can get past it, with a USB keyboard, restart and press the T key to enter into Target Disk Mode. You should see the FireWire and Thunderbolt icons on the screen are you able to get to that?

Thank you kindly @DanJ.

I took the unit to service as I only checked the SSD and the RAM. I suppose it's the NVidia graphics card but I will let the technicians to do a diagnostic and try to repair the damage if possible.

I will start looking for a Logic Board to replace the old one. I already did it with my old MacBook Pro 17" Late 2011.

Thank you kindly.
