Hi, new to the forum. I am hoping somebody had encountered this problem and may have a solution. I was playing Gravity Rush on my PS vita 1003 one day, then an error came in "GPU crash" and the vita shutsdown, I was able to to turn it back on and I've continue playing for a while, then suddenly it turns back off again. Now when I tried to turn it back on, it will only flash the white PS Logo on the screen for about a second and turns back off. I've tried doing a soft reset (20-30 seconds holding the power button) but it will only do the same of flashing the PS logo on the screen every 5-8 seconds or so. I tried doing a hard reset (Power button+PS button+Right button), but it will do the same thing. Then I've opened up my vita and disconnect my battery for as long as 2 hrs., when I re-connected it back, it will still do the same thing. I've tried connecting the USB cable to a different charger, same problem, then to the PC..one thing I've noticed, when connected to the PC, the PS logo will not flash on the screen, when I hold the power button. Hopefully somebody has a clue on what is going on. BTW my firmware version is 3.68, PS Vita 1003 running on H-encore. TIA to anyone who can help.
