Well speaking of "arcane",and "those kind of guys" are still around, for clarity see the answer below :)
So what you need to do is open it, remove battery, and clean the mother board and plugs ect.... using NON metallic cleaning objects like toothbrush and q-tip.
Use alcohol (for grease) and Vinegar(or pure lemon juice without sugar) for calk deposits ...

Years ago, an independent Mac repair guy opened up the case of a Powerbook on which I'd spilled a little coffee, poked very gently around with a q-tip, probably with alcohol on it, but maybe only water, cleaning up all the little dried granules he could see.
Note that I am not recommending you do this, just passing along a story.
He also knew what wire ...

On my MacBook Pro with OS X 10.8.3 I have a configuration file for each external display I connected to my Mac in this folder: /Library/ColorSync/Profiles/Displays. If you can identify the file for your display from that list, try moving the file to a different folder and reconnecting your monitor. This solved an issue I was having with colours not showing ...

Currently, you can only use a 2010 or 2011 27" iMac with this Adapter.
iMacs build in 2009 and before doesn't support input signals.
iMacs build in 2010 or 2011 support input, but you have to convert the
HDMI signal to MiniDisplayPort.
iMacs with Thunderbolt does support input, too. But there is no adapter yet to convert the signals. Thunderbolt is ...

There’s a piece of software called Display Rotation Menu by Mage Software which puts an item in your menu bar with a number of reflection and rotation options. It’s free to download from their website:

The page hasn’t been updated in several years, and I don’t have a Lion system to hand, so I don’t know whether it ...

You can use the MiniDisplay Port on the back of the iMac and put the iMac into target display mode, turning it into an external display.

You can use the pmset command to "ask" power management if there is anything that will prevent sleeping. In this first example, I have recently rebooted, and there isn't anything that should prevent the system from sleeping:
$ pmset -g assertions

LCD displays have short and long term effects due to the physics of how they polarize light and how the transistors turn on and off pixels by passing current through the liquid crystal.
If you were to take a photograph of your screen and show what you are seeing we might know if this is short or long term image persistence or perhaps something else like ...

The proper jargon seems to be a burn in. This extensive post at the apple forums holds a lot of answers.

I found an easy way around this and I hope it helps people. I tried resetting the NVRAM and it did not help. I am pretty sure it is due to flaw in the OS upgrade.
Here is the fix. Set up video so that when you move to the top left corner, the video shuts off. When you come out of sleep, if the resolution is low, move the mouse to the top left to shut ...

Ok so I bit the bullet and took it into an Apple reseller repair shop, who (after 7 days) identified that there was a known defect with the motherboards in my range of macbooks, so it was covered with zero cost.

Have a look at Stay or Moom.
Stay is specifically designed to combat this problem. It remembers window positions for a given display configuration, then switches between them as you switch displays. So when you disconnect your Thunderbolt display, your windows will resize to your settings for internal only.
Moom is a bit more of a general purpose window ...

I got the same problem with two Dell XPS 13 when one is stacked on top of the other. When being stacked on the other, the top one goes to sleep and pressing the power button can't wake it up; when it however moves out of the bottom one's frontal edge, it wakes up automotically. This is true even the bottom one is powered off.
Conclusion: The sleeping mode ...
