I recently noticed that 5 or 6 horizontal lines have begun showing up at the bottom of PSVita's screen. The lines are stacked on top of each other with a 1 pixel space between them.
The top line of the stack usually flickers a bit.
Restarting the machine didn't remove this problem. In fact, the lines are there during the start-up process.
The lines show up dark when in front of a bright picture and bright when in front of a dark picture.
As I was playing Mortal Kombat yesterday, the lines did seem to gradually go away with time, but there are still 2 or 3 of them.
When turning the system back on this morning, there was still 5 or 6 lines showing up.
I have the WiFi model.
Should I contact support for repair or replacement? I got the system at XMas so I'm well within the 1-year Warranty period.
I'll try to provide a picture of the problem when I can soon.
