Go to system preferences, click on the control panel called Universal Access once in there under display it is probably on white on black the setting you should be on is black on white. I'll try and get back to you with regards the keys as I have had this before but can't remember how I corrected it just now. Hope this helps.

CAN YOU PLEASE EXPLAIN TO TO ME WHAT IS EV COMPENSATION AND HOW DOES IT WORK


EV compensation is "Exposure Value compensation". The camera contains an exposure meter which determines how much light is on the scene and sets the exposure appropriately. However, this meter does not know WHAT you're taking a picture of, nor does it know what effect you're going for. The best it can do is to assume you're taking a picture of an "average" scene and want it to be of "average" brightness. It does this by assuming the scene is "middle gray," halfway between black and white. Most of the time this works fine, because most scenes are, well, average.
However, this is not always the case. Suppose you're taking a picture of a white dog playing in the snow. Almost everything in the scene is bright white, but the camera doesn't know that. It tries to make the scene middle gray, and the result is that you get a gray dog playing in gray snow.
On the other hand, suppose you're taking a picture of a black cat sleeping on the hood of a black car. Here everything is black, but the camera doesn't know it. It tries to make an average scene, resulting in a gray cat sleeping on a gray car.
EV compensation allows you to override the camera's exposure setting. In the first example, you'd want to add two or three stops (positive EV compensation) to force the camera to render the dog and snow as white instead of gray. In the second example, you'd want to subtract a stop or two (negative EV compensation) to render the cat black instead of gray.
How much EV compensation is correct? Well, that depends on the scene. With a digital camera, you can look at the picture and see whether the dog looks white or the cat looks black. Film photographers take lots of shot, using various levels of EV compensation, so that one of them would come out right.

Looking to replace the cat on my 1999 volvo v70 all wheel drive and the replacement cat does not have the O2 sensor mounted in the middle of the cat. does this make a difference ?


I would find the OEM Cat design.
I know you want to avoid the dealer one
due to cost.
I would think Walker should make it,
check their web site and your local
auto parts.
If you get something different, then
maybe the wires won't reach etc

Negative screen image


Look in System Preferences for Universal Access, there is a Display option which says Black on White(the normal setting) and White on Black (the setting that has been enabled).

There is a keyboard short cut to change the setting, it involves pressing four keys - Apple, Option, ^ and 8.

Can You state exactly what the toy is. Maker, Name, model, pictures, year of manufacture. Details help the research process.
But try this...
If talking about a circuit, look where all the solders are, You can sometimes find a solder point that doesn't have a smooth top it will look like something broke off. Find two of these...To tell the difference when you find them which wire goes where, the solder point that traces back to any capacitor ( a cylindrical component with two leads on its bottom that has a black strip down its side noting which lead is negative.) The black wire can be soldered back to the point that traces back to a negative lead. Then the positive (red) will go to the other one.

If this does not help see if you can upload a good quality pic of both sides of the circuit if possible.

LCD flickering / Purple/Green Photos


I'm sorry to tell you, your CCD its death, no human intenvention can fix it, you must replace it, when a CCD fails, it's literally death, you can not fix it, its a very delicated part, and the fail it's some kind of microscopic evaporation or filtration problem, I'm pretty sure that it has no fix. I spend the last year trying to fix mine, but with negative results.

This is really sounds like a keyboard issue. From your description it sounds like your ?.? key is locked in the active position, note that the key doesn?t have to be down for the contact below to be engaged. This isn?t uncommon, especially with older/cheaper keyboards. A quick test is just to replace it with another USB keyboard, even a Windows keyboard will do for a test. If that solves your problem you can try taking it apart to clean, however, if it?s in warranty I would just call Apple support. If its fairly old I would just bite the bullet and spend $35 for a new one.
