If the replacement battery seemed to work fine at first, chances are everything is working fine and perhaps the screen had a loose connection? Hard to tell but I would suggest opening the device and unplugging the battery, then screen, and then plugging both of them back in(battery last of course). If this brings the phone back to life you may want to perform a back up of the data then factory reset the device. If possible, you could get an in-line multimeter for cheap to see how much charge the device is taking and whether the problem lies with the battery, charging port, or software. Good Luck!
