    I turned off all the imac was ok, when I tried to turn it on nothing happened. I tried different variants, hundreds of times, it did not work, took the screen lights up 1 LED. What to do? the power unit is broken?

    I do not understand what you mean with the screen lights up 1 led .. could you explain that a little more to me?

    My iMac from 2009 broke down, boom, turned off. I couldn't get a peep out of it, no lights turned on, no buzz, no hard drive spinning, it was indeed the power supply unit, apple fixed it for 140 euro or something.

    But if you have an LED light up, it is getting power .. so I am curious to hear what you mean with that specifically.

    How do you possibly see that? It's all in the inside of the iMac?

    By what you have told me, and it won't make a sound, no lights, nothing .. it sounds like you can try two things. One, get another power chord that's suitable for your iMac and try that, if you get the same result, try two. And two being the option to just go to Apple and let them take a look.

    Could be many things, not worth sending to Apple since it is 5 years old and they'll charge your more than it's worth. Try connecting a seperate screen through a mini display port/thunderbolt adaptor see if it powers up. If not could be the power supply or a dead graphics card. I doubt the power supply if you have LEDs lit up on the logic board. Luckily both of those are easy 100ish dollar repairs since the 2011s have slotted graphics and seperate power supply boards. Buy the parts, test send back what you don't need.
