Regrettably, I believe I can assure you, your computer is not fixed.
In my opinion Apple makes its fortune not by producing exeptional hardware, but by designing an exeptional visual and ergonomic package using, relatively cheap, and easily sourceable components. Apple also designs some ot the best and most durable and useable software in the universe - which runs brilliantly on fairly "run of the mill" hardware.
The upshot (IMO), is that Apple software is indisputably the finest available,while the hardware is cleverly packaged, and often 2 or 3 generations behind that of its competitors. This is maddening, because while Apple continues to advance hardware, like Mercedes advances automotive technology, the hardware is mostly "GM" grade.
In terms of Software, Apple delivers all of the sizzle one has come to expect from the brand. In terms of hardware, the sizzle remains, but the steak is decidedly stale on the average, and has a slightly, or even completely spoiled flavor at its worst.
While other OS manufacturers struggle to build OS's which attempt to make the best of the latest and greatest hardware possible. Apple seems to sit back, and carefully assess the best combination of goood and cheap, and appears to build its newest offerings around proven, anrd relatively inexpensive internal hardware.
I don't knock the hardware engineering. Overall, I think Apple balances the best of the best of physical technology which is a generation or two behind ( to be kind), and configures its logic boards etc, in the most effecient ( and ultilmately - low cost) configuration possible.
In summation, where useable softwar is concered, Apple is the absolutely the ultimate. In tems of hardward Apple can do better, and shoud do better. Much better.
Before swithing to Macs, i built, and maintained PC's and Neworks for years. I understand the need to balance the best software avaialbe with the most cost efficient hardware available.
That being said, I love my 27" Imac. I love the softwars system. I love the functionality. I hate issues like Black Screen, and the lower LH portion of the LG display being darker than the rest of the display (this is still an issue).
As a designer I love the aesthetic, and as an IT admin, I am intensely disapponted hardware (not the very cool mono-aluminum case -and giant sized display). I hate that I am out of pocket for hardware which does not appear to be up to the same standards of the excellent software.
The fact that Apply remains largley silent on issues affecting numerous 27" Imacs, also creates a sense of profound discomfort with me.
After years of troubleshooting anc reparing computers - figuring out what was going on with my particular Imac, was both logical, and a matter of correct trouble shooting protocals.
The notion that a Mac is anything mystical is widely propofated, but unfortunately completely misguided.
There are two reasons the hardware does not perfom. 1). Hardware is defective 2). Software is not doing what it is suppossed to do. 3). A combination of 1). and 2).
If you have taken your Mac to a "diagnostic center", they are either capable of correctly diagnosing the probem (prefferable), or your Mac Tech is an incompetent.
Because I knew what to look for, my issue cost $26 for a part from Radio Shack. When I hear that people are shaking their Macs, or monkeying with the wireless keyboard and mouse with limited success, I cringe.
!st, check to make sure your remote component batteriers are fully charged and operationsl. 2nd make sure your peripherals are turned on and dislpiaying tiny green lights (this means they are looking for a blue tooth connection).
Make sure bluetooth on your Imac is enabled. Then boot your mac up and see if it now works.
If you think it is your blue tooth, keyboard and mouse, replace the batteries in your USB keyboad and mouse, plug in, and reboot. If you still have a black screen, go to Radio Shack, or whatever you Brits and Pakis, and Spaniards have, buy an apple to VGA adapter, and plug an SVGA monitor in to see if you have a picture. If you do, it is probababliy not the video card, Let the computer go to "sleep" and wake up.. If both screens wake up, it is software. Upgrade to the newest OS version your system will support. Your crappy files will be replaced, and your Mac should run fin without and external monitor.
If only the external monitor works with the Radio Shack adapter, use it. $250 for a decent monitor is far cheaper than a new Imac 27.
Smacking, cursing, kicking your mac, or throwing it out the window will not improve performance.
If you don't want to fix it yourself, you have a couple of options. Take it to someone who is actually competent fo fix it at a reasonable cost, or buy a new one and pay a "genius" to transfer you critical files.
Breath a sigh of relief. Unless your hard drive has completely crashed, all of your work can likely be recovered.

The computer is just a tool, it is what your have created with it that is of real value.
