White Screen of Death on all Partitions (Including Recovery)
Hi,
I have a mid 2011 27" (3.4 GHz Core i7) iMac that as of last night is throwing up the White Screen of Death about a quarter of the way into the Apple logo boot up.
I have tried booting into recovery, a Windows partition, and an SD card with bootable Yosemite ISO mounted to it... and the result is exactly the same, a WSOD about 25% into the progress bar.
I have also tried single user mode to check for modified drives, I have reset PRAM, and I have attempted Safe Mode. Again, all with the same white screen and eventual reboot.
I'm presuming/hoping that as a result of it being able to at least show me start up options such as Recovery and OSX/Win partitions, that the fault is more software than hardware. But without being able to gain access to Disc Utilities I'm up the creek!
Does anyone have any further ideas?
Thanks.
Is this a good question?
What happens when you go into Target Mode, do you get the Target Mode Icon on the display? Have you tried using an external monitor to see if the display is just bad, I'm assuming you are getting it to boot just a white screen here.

Please give us the last four digits of your serial number so we can correctly identify your system. You'll find it on the underside of the stand. With that we can tell you if your system is on a recall list.

The issue occurs in both OS X and Windows. A white screen in OS X, and blue lines then black in Windows.
The last for characters of the serial are DHJW.

See that's what a lot of sites say, but I know when I ordered it, I upped the machine to an i7 processor and 2GB graphics card, both of which show usually on my "about this Mac" screen. I've also personally upgraded the RAM to 12GB upon its arrival in 2011.
