This is quoted from one of my post:

"If a bright pixel appears at all shutter speed...then this is a dead pixel. The only way to cure is to do an exchange (at AP or Olympus SG) or get Olympus SG to replace the CCD.

If the pixel doesn't appear initially but get more obvious and bright as the shutter gets slower, then this is a hot pixel. Don't worry, this is normal, even my DC has a few at slower shutter speed. What u can do is to pay Oly SG a visit and ask that to upgrade ur firmware...that'll will reduce (not eliminate) the amount of noise and hot pixels."

How much does the CCD cost?

The CCD cost the bulk % of the total cost of the camera. It is the most important piece of equitment in the camera.

They come in different price in terms of quality and size.
