OMNI1500LCDT ups LCD and battery surge no power

Got this UPS on eBay as a "working unit" long story short it was a scam.

Now the UPS passes power to the normal AC power strip it has. However the battery + AC power outlets don't pass voltage.

I also tested the LCD desplay and its getting a VERY low voltage

Now I am thinking this has something to do with it having no batteries, but that shouldn't be the case, how would it charge if they were to run out of power? Has anybody here had this issue with there UPS?
