Hi @sassydragon ,
The tablet's digitizer (touchscreen) has either got a loose connection or is faulty and needs to be replaced.
Here is a link to a video which shows the dis-assembly of a Polaroid 10.1" tablet. Hopefully it is of some help in dismantling the tablet to gain access to the digitizer
If it is determined that the digitizer is faulty, here is a link to a supplier of the replacement part. It is not a recommendation to use the seller, it is shown to give an idea of the cost of the part. There are other suppliers that may suit you better. Just search online for Polaroid L10 digitizer part for results.
Hopefully this is of some help.
