i have a spv 7'' android dual core tablet model is tpc0707. ive had ot for less than 2 weeks. i have used it very lightly and last night i locked the screen and when i went back to use it it wouldnt turn on. ive tried charging it (although there was 50% charge), ive also tried hold the power button with the volume button, i also pressed the little reset button on the side and i also plugged it into my laptop but still nothing! if anyone knows what i can do to get it to turn on that would be great.
