Today I let my PB run out of juice, it shut off by itself and took me ages to get it to restart. When it finally started there was a line down the centre, like the screen was 2 512x600 LCD panels side by side, one slightly darker than the other, and the line is visible through UI elements, and in games. Very distracting, like a dead pixel, only there's 600 of them. Anyone else have this happen? And any idea on solving it? There's definitely no physical damage.
I would also suggest a restart trying each method if the one before does not fix the problem
To fix an issue, try these in order:
Restart using the Battery Icon and press Restart
Press and hold the Power button for 10-15 seconds. Then leave it for 20-30 seconds and see if it restarts.
To REBOOT:
Press and HOLD all three keys for about 10 - 20 seconds: PowerOn, VolUp and VolDown. Start with the PowerButton. Keep holding past the 3-choice options screen. If you hear a shutter type sound, you've taken a Screen Shot and probably missed the PowerButton.
