turn on Computer, Fan turns on, and Screen doesn't turn on
my landlords who are both in their 70's have had the iMac flat screen since it came out. They very rarely turn it on (maybe once every 6 months). This time they turned it on and the screen wouldn't turn on, even though the little white light on the corner of the screen was on. I'm a PC user who is their tenant and they don't have the user manual. Is there anything I can try before they take it in to a technician? Thanks in advance!
Is this a good question?
