With respect to a brody and his 4 blue squares, this sounds like a problem with your display. I don't see a power mains issue causing a display getting dark on only one side. Apple Hardware Test might show something, but seeing as you said you got it "in the end of 2009", you will be getting close to the end of your 1 yr warranty. So, unless you have the protection plan, you should call Apple ASAP to get the issue documented, just in case your warranty runs out before the repairs happen.
I ran the TechTool Deluxe (ver. 3.1.3., there was everything okay, except the VIDEO RAM test, there is a red exclamation point and a message next to it "failure". Is there a way to let the TechTool Deluxe fix this issue? Yes, I think it's reliable. Why should this be an problem? It's a normal power outlet as it's common in germany. What is "a good ->UPS<-" ? If what does?
Hi. I'm not sure if this would work, but you could try resetting the PRAM and NVRAM. It's worth a shot. Follow these instructions to do so:
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these
keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

I don't think it'll solve your particular problem but it will provide clean power and offer some protection against power cuts, brown outs, etc.

there is a red exclamation point and a message next to it "failure".
The iMac can only be fixed by an authorized service technician when it comes to VRAM. And yes, that's not generally a power issue, but it could be prevented in the future by good clean power. Once your test says there is an issue, it is one Apple can usually believe.
they will repair or replace my iMac without any cost, because I have the Apple Care Protection Plan?
As long as they determine you couldn't have caused the issue yourself. So just go in there calmly and explain the test revealed what it did that one time.

Cool, didn't know if you had AppleCare or not. All of the other suggestions are good things to try, but I still think you have a bad display. Specifically a backlight problem.
If there was a video card problem, you would loose the image, not just part of it. Seeing as TechTools is indicating a problem with the video RAM also, I would take it to a service provider or contact Apple for warranty service.
