My 5 month old eMac (Radeon 7500, 1GHz) has what would be the equivalent of a dead pixel. It's not dust on the screen. Being only 5 months old, it's still under the 1 year warranty, so should I take it back to the local Apple Store, or just deal with it?
Also, for about the first month after we bought it, there would be occasion 'sparks' on the screen - bright white spots, causing a horizontal line across the screen. I asked a couple people at the Apple Store, both said to bring it in if it continued. Of course, it stopped doing it after that.
I'm leaving in a couple hours for the Brickyard 400, and will be back Monday.
