If that doesn't work, here's another option. I was able to get in (with the help of Apple Support, and set up voiceover. Then airplayed it to the Roku.
This will all take eons to set up and figure out but once it's set up, you have a working option. Be prepared to break a set of plates out of frustration in the meantime.
Make sure you turn off the "verbosity" or it will drive you insane. Somewhere in the accessiblity preferences. With the voice commands, turn on the option to add display to the upper right menu bar.
you can turn voiceover on and off with cmd f5.
Cmd-tab to finder
ctl opt mm "menu extras". This brings you to the top right display bar with the icons like display, graphics, wifi etc .
ctl opt right arrow (or left arrow to go back ) until you get to "display
Ctl opt spacebar to select the menu, then arrow (ctl opt arrow? not sure) to go vertically down the display menu. Go until you get to your TV or Roku listed in the menu.
Makre sure airplay is on.
Ctl opt spacebar to select your TV. You should now be able to see your screen.
Note - sometimes airplay will confine the cursor to the left side of the screen. IF that happens, just go back in again, and while doing that, make sure you are moving your cursor to the right on the trackpad with your finger as it's connecting.
I have noticed also that sometimes when hard shutdowns happen during airplay, the screen will come back on upon bootup. Perhaps this is similar to the issues described in prior posts with the turning it off puts it to sleep.
However once something requires the use of the dsicrete graphics card cones on, such as Chrome, the screen will switch to that card and in so doing, go black again. So in that case you'll have to have it airplayed.
THsi allowed me another year of use on my compute, as well as to get in and get any backups. Hope it helps someone.

I had the same problem with both the A1278 and A1342, either black screen or white-out. Until I started looking at lightweight software and decided... nothing to lose... and put Linux antiX 23 on the A1342. And then put Linux Mint Xfce on the A1278.

Have you tried Linux lightweight programs... that's what worked for me. I had two MacBooks with the black screen of death and tried every thing I read others doing. Linux Mint Xfce went on one machine and antiX on the other. I bought both of these machines used and they were pretty much used-up when I got them... not anymore. Hate to look like a Mac-traitor but it is what it is.
