Have you tried to put back the original screen? Even if it is cracked, if it was working before then that can help you troubleshoot the issue.

If the original screens also suffers from the same symptoms, then you need to check the condition of the connectors on the logic board to see is there are any damaged pins or debris that could impede a good electrical contact. If all if that looks good, then the issue may be on the logic board (it could still be battery related). At some point, you have to determine how much troubleshooting you want to perform.
