Displays an Apple for about 20 seconds and then reboots. Any thoughts
This iMac was brought to me for data recovery after a lightning storm. It powers on and boots straight to an Apple, no status bar, and then sits there for about 20 seconds before silently restarting the process. The iMac A2115 27" 2020 does not respond to wired or wireless keyboard inputs for option boot, target disk mode as well as both internet and non internet recovery and diagnostics. I can zap the PRAM, once, and upon reboot the machine returns to its previous state. It will only reboot once no matter how long option -cmmnd-p-r is held down. The audio, present after the first PRAM reboot, returns to silent for further reboots until PRAM is attempted again. I was successful in getting the mac into DFU mode and was able to revive the software with zero errors, but zero effect. I have pulled RAM and tested with known good RAM and the issue remains. I am at a loss and throwing this out there to see if anyone can help. I'm just trying to get the data off. Cheers!
Ist dies eine gute Frage?
