An increasing number of complaints concerning visible scan lines on the new PSP-3000 portable console have drawn a response from Sony, which has admitted the issue but indicated that a fix may not be possible.
Already launched worldwide, the new PSP-3000 is the second minor revision of the format after the slimmer PSP. The new version features an improved LCD screen with an increased color range, higher contrast ratio and improved pixel response time, to address previous complaints about image "ghosting". The new hardware also includes an built-in microphone, improved buttons and other minor hardware changes.
However, the screen changes appear to have come at some cost, with many users complaining about visible horizontal scan lines on a variety of different games.
Responding to the issue on the website PSP Fanboy, an unnamed Sony Computer Entertainment America spokesperson commented: "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."
The spokesperson said 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."
