[QUOTE="Charelene, post: 1772485, member: 396029"] Greetings to everyone on forum. Recently while using my iMac normally, the screen went blank after 15 mins of usage and it wont turn on under any circumstances, nothing happened when I pressed Power button. I decided tear down the screen to have a look and the thing is, that I was able to turn it on for a little bit, heard the chime, working fans etc, but it shut down after few seconds. Trying to investigate the issue, I found out the next thing. When you plug in the power cord the 1st diode on motherboard turns on and off for a second and then turns back on. When you press Power button, it turns on normally, but after some time it turns off and the 1st diode goes off as well, until you unplug and plug back the power cord. I'm thinking that it could be the power supply fault, but I'm not really sure. Can anyone help me out? Is it the PS issue, or there's something other broken? [/QUOTE]
