Won't start after dissasembly - 1 LED light goes off when powered
I was going thru this guide (Installing iMac Intel 21.5" EMC 2389 Dual Drive) to replace my current SSD (in the optical drive) with another one. After that my iMac won’t start. When I connect the power the first LED 1 lights up, but when I press the power button the LED 1 goes off. So I haven’t had any luck getting LED 2 to show..
I tried to connect the LCD cables again and try to start but no luck. I didn’t touch anything on the power supply or anything else as far as I know. I was going to give the iMac to my mother as I’m getting a new one and I don’t want to invest much money or time on this old but glorious computer. Could maybe the power cord be the problem? Feels like my only hope right now.
Is there anything fairly easy I can try, or is it just over for this one?
Grateful for help :)
