The tablet worked fine except the cracked screen. I install a new screen and put everything back together except the rear plastic part. When I connect a working charger to the tablet, the screen will not power on or show it is charging. I hooked the broken screen back on to the motherboard and I get the same result.

brentkhack , It sounds like a connector or a component may have come loose. Open the device and clean all the connections battery, display, etc., with a Qtip dampened with 90% or better Isopropyl Alcohol, look for any damage pins/terminals and reseat the connectors to ensure good connection and use a magnifier to check for missing, loose, damaged components. Check battery with DVOM to ensure battery is good and charged. Good luck.
I hope this helped you out, if so let me know by pressing the helpful button.

I did clean like you said and checked the battery, which is good. But the connector on the motherboard that is below the battery looks to be damaged. There are two rows of metal connectors and half of one row are flat and not straight up. So I guess I found my problem. So now the issue is this is a Sprint LTE tablet and the motherboard they sale here is for wifi only. Any clue where I can get a replacement board?
brentkhack, from what I read in the link below, they were all wi fi, use the model # off your phone to do a search for mother board or contact ifixit at the second link to see if there part is compatible for sure as the unpaid volunteer site here does not have anything to do with the sales of parts.
