Sony DSC-T20 cameras: sometimes they don't take pictures
The occasional pink or silver model will vibrate, but not shoot.
Although it only applies to a small percentage of units on our shores, today Sony announced that "A certain number of DSC-T20 cameras (in pink and silver only) will vibrate when the power is switched on and will not be able to shoot pictures" due to a "mechanical failure that affected the lenses." Ouch. Since there haven't been that many incidents thus far in the U.S., this isn't a recall; Sony will simply repair any faulty units for free, from July 10, 2008 to July 9, 2011. It seems that overseas there's also an issue with the T70.
