Help HELP! Just bought it but it just flashes on

I just bought a pandigital r70f200. It didnt have a charger but supposedly had worked. Charged it but it still will only flash on for about 1-2 seconds (screen is black & has 2lines, 1linespace, 4lines; says something to do with "partition table status = 0" on 1st line of the 4) then off for about 20 seconds. No reset pinhole, Ive tried holding power for 30+ seconds; power + vol up + vol down; power + vol up; power + vol down, but nothing changes. What can I do???
