IMac Dead, What to do?

Question

I have never had any problems, we love our imac. Unplugged it yesterday a.m. when we went away for the wk-end, now, when we plug it in and try to start, nothing.
I am having problems typing this on my husband's laptop from work,it is a pc,and doing all sorts of strange things. Anyway,we have not opened the back----if we do, and try to do some of the things suggested in this forum, will that negate or be a probem with Applecare? I received this computer on or around 2-14-05, I have Applecare for 3 years. So should we try the lcd stuff, or just call them? I have looked up the registration numbers, and I believe mine is in the last batch of computers with problems,so not totally unexpected,but as I said, never any problem before.
I am so disappointed. In shock,really. And I think this stupid windows laptop has a virus, as sometimes what I typeends up in the previous paragragh. My apologies,and my humble submission. Thank you in advance,and I knowfor sure now,I hate using windows.

Hi jada. I'd certainly ring them first in your situation. They may well walk you through the process of undertaking an SMU reset over the phone.
You won't void your warranty by simply following the startup / SMU reset instructions in http://docs.info.apple.com/article.html?artnum=300908 though. The "first generation" and "ALS" models are designed for a certain amount of "user service". Its only the iSight and dualcore Intel models that you shouldn't open the back of.
But first of all, have you made sure that you aren't simply suffering from the power cord problem discussed at http://docs.info.apple.com/article.html?artnum=86817 ?
