Your problem sounds much like mine. However, mine would blink a few times when I plugged it in, then stop working.
I believe the type of cable that the tablet uses is called a USB A to Micro B cable. You can find these on google and such, but a lot of things use these cables; I believe some cameras and cell phone chargers use these cables, so you may want to check your drawer full of cables if you have one.
If it still doesn't work, then you might have either found another cable that was broken or your tablet is out of commission.
