My display doesn't work
For a while I was limping along using my iMac with frequent blackouts which seemed to repair themselves after a cooldown period.
Later I started using an external monitor and was fairly happy. Then the whole thing went dark. Now it seems to power up but no display either on built-in display or external monitor.
I wish to get my files onto a thumbdrive and also to repair the computer.
Is it the led board? or what?
Thanks for any ideas
