Im recently getting weird vertical white lines on my tablet's screen these lines sometime fade and sometimes come on their own much like on the g2. And also my tablet doesn't detect any available wifi or bluetooth devices i also have my g4 with me and it does, i have also hard reset my tablet in luck of success but failed now i think its a hardware problem. For the lines, I've seen youtube videos on people attaching electric tape on some stuff near battery but im not sure what that stuff is on my tablet i managed to open my tablet and now i have kept it in some heat thinking maybe that'll work but it would be really kind if someone helped me and can someone tell me where should i attach the tape? Heres the pic
