The Sony Corporation has responded to the dead pixel issue with a response that will bring relief to the Playstation Portable (PSP) owners. The black pixels are a common problem in the LCD technology, and were very common in the earlier PC LCD monitors. But the production processes have improved, and such displays are far less common these days, and customer have learned to expect 100% quality.
Sony Corporation stirred the audiences at first by suggesting that dead pixels on the display of the PSP was not a sufficient reason to replace the unit under warranty. But now they have made an announcement that the unit can be replaced, but Sony recommends to use the unit for few weeks before replacing, in order to find out if the defect really harms the playing experience.
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."Source: GameSpot
