Sony have downplayed widespread reports of 'dead pixel' LCD screen problems for their new Playstation Portable (PSP) handheld games console and media player, saying that the warranty is still in effect and defective units can be exchanged.
Soon after the PSP launched in Japan last December, reports began to surface that some units' LCD screens suffered from pixels that were either permanently light or dark. Within 24 hours of the portable's North American launch, similar complaints began to reverberate around the Internet.
The locus of the complaints was, ironically, the official PlayStation forums, which was temporarily down yesterday following heavy traffic.
An informal survey of the dozen-odd PSPs in the GameSpot offices found half had at least one pixel that stayed white or dark constantly. While these dots were almost all invisible while playing games, they did stand out when displayed against a black or white screen.
While commonly referred to as a "defect," Sony says the off-colored pixel problem is common in all LCD screens. "A very small number of dark pixels or continuously lit pixels is normal for LCD screens, and is not a sign of a malfunction," a representative for Sony Computer Entertainment America (SCEA) told GameSpot.
Page 13 of the PSP manual puts it this way: "Red, blue, or green spots (bright spots) or black spots (dark spots) may appear in certain locations on the LCD screen. The appearance of such spots is a normal occurrence associated with LCD screens and not a sign of malfunction. LCD screens are made using highly precise technology. However, a very small number of dark pixels or continuously lit pixels exist on each screen." The manual also warns against exposing the LCD screen to direct sunlight and leaving still images on the screen for an extended period of time, as both could damage the display.
The Sony rep suggested that PSP owners who encounter the pixel issue should try the device "for a week or two" to see if it continues to bother them. "If you find the spots are interfering with gameplay/video viewing during this period, we will support the various elements of [the PSP] warranty," the rep said. Each PSP comes with a one-year limited warranty, which is on page 125 of the PSP manual. If a PSP is "determined to be defective" by SCEA, the company will see to the "repair or replacement of this product [the PSP] with a new or refurbished product at SCEA's option."
