iMac 24'' won't turn on

I've always turn off my Imac at the end of the day, but I don't unplug the power cable from the outlet.

Yesterday the computer didn't start at all, I've plugged it in another outlet , still nothing ... after a few hours I tried again and it started.Like always at the end of the day , I shut it down, and today it doesn't turn on again, I'm pressing the power button but nothing.I've checked the cable , the outlet , everything is placed correctly .

Thank you in advance for any kind of help, suggestions.!

Remove the front bezel. There are diagnostic lights to the right of the RAM slot. With the machine plugged in try to start and observe what those lights do and let us know. Here's how to get to it: iMac Intel 24" EMC 2111 Front Bezel Replacement

update: yesterday after a while I plugged it in and turn it on and it started.So I was able to run the apple hardware test which didn't show anything wrong, but the Istat pro shows a power supply temperature of 85 degrees C .

Is there any chance that the fans are not working properly ? there might be some dust accumulated in there?

Thank you very muck for your prompt answer!

OK, I looked at the diagnostic lights.Led no .1 stayed on for a second then went off.One time it stayed on for a longer time and I was able to start the computer and all the lights were on. What do you think it is?

kung take a look at the capacitors on the logic board. Look for ones that are swelling and /or corroded.
