Hi folks i have been given one of these iMac’s by a customer, and although there is lines on this, its rather annoying, also i have an adapter that is plugged to a VGA cable to my external monitor but nothing showing up, is there some sort of buttons or process on the keyboard i need to do and press, or should i just sell it up, as scrap. Got a 1TB SSD Drive inside this and i can see images on screen if i drag the mouse in a folder i can move it to the top of my screen and i can see it, but its rather useless right now..thank you i appreciate any help that there may be out there….
