New PSP, new problems. The recently released PSP-3000 does get rid of the PSP-2000's ghosting issues, but has issues all its own: On the official PlayStation forums, PSP-3000 owners are bringing word that the new PlayStation Portable suffers from scanlines and icky interlacing defects during video playback and gaming. One forum member writes, "I am not happy about my 'upgrade'." In an official statement, Sony says this is no accident. According to Sony:
On some occasions, scan lines may appear on scenes where brightness changes drastically, due to the hardware features of the new LCD device on PSP-3000. Installed with this new LCD device, PSP-3000 offers more natural and vibrant colors on its screen, but the scan lines have come out to be more visible as a result of improving response time to alleviate the afterimages on PSP-3000. Since this is due to hardware specification, there are no plans for a system software update concerning this issue.
Why update it with a software update when they can fix these issues with hardware update. PSP-4000 here we come!
