The fact that the line does exist in the bios kinda indicates that it is probably hardware related. You could try to contact the seller to resolve the problem or if you feel comfortable with disassembling the tablet you could check that all the connections are proper.
Appreciate the response buddy. Yeah already ordered another one. Only had it for a day and got it from banggood/PayPal so should be alright. Going to officialy stop trying to fix it now. Thanks again
