Till, The you have a tear in the flexable circuit board that connects the aperture assembly to the lenses Main PCB. You can replace the aperture unit, but the cost of the part will be high.

The best solution I've found to remove corrosion is boiling water. I take the Main PC Board out of the phone, boil water in a coffee cup in a microwave then place the board in the water. VERY IMPORTANT DO NOT PLACE THE BOARD IN THE MICROWAVE. After a minute or two carefully remove the board and scrub both sides with a tooth brush. When the board is completely dry return it to the phone. I've used this sucessfuly many times with water damaged Ipods, Iphones, & other electronic devices at the repair shop I work for.

Sounds like the shutter is stuck closed. I've seen this several times on the S2 IS. Usually there is an oily substance on the shutter blades.

The Canon Rebel/300D LCD display cannot display a shot count # greater than 999. This is not an error with the camera, the LCD simply does not have a fourth digit in the shot # display. Just use the camera normally with the 4Gb card. The number display will start working again when the amount of free space on the card drops to a level where it will not hold more than 999 more pictures.

Error 99 is a generic call for help. 95% of the time it is a failure in the shutter. It can also be a lens problem or flash problem.

The PS3 Blu-Ray drive can still read DVD's? What about Blu-Ray Movies? The laser diode in the drive actual has 2 laser outputs, a red laser and a blue. The red laser is used to read DVD's & CD's, while the blue reads games & Blu-Ray movies. Most likely the blue laser is damaged as it is much more sensitive to heat. The solution is replace the laser $@!'y in the drive. Be sure to get the correct assembly, you can identify the drive by its model number inscribed on the laser & motor is mounted on.
