Make sure you have a good cable connection into the print head. Failures on the print head board alone can cause the UM3 to not boot up. It's very common for pulling forces to pull the connector right out of the print head (partially).
There are 4 longs screws. Remove the rear 2 screws only and then a panel on the head comes off. Make sure the cables is pushed firmly into the connector (if you choose to remove the cable beware there is a clip holding it in place that needs to be squeezed).
If that doesn't work, because it sounds like you had a "head flood" there can be much damage while removing all that plastic. I'd take the head all apart. check all the cabling. Try powering up with it disassembled but electrically connected. If that still doesn't work I'd order the PCB in the print head. It's not expensive and can be ordered separately from any reseller but for you I recommend igo3d.
Alternatively if you have time (and not a lot of money) then I'd get the "olimex serial-cable-f" and if you know linux somewhat you can look at log files and see what code is giving you errors. This guide will tell you how to use the cable and at the bottom where to find some important log files. Google can also help you figure out why it isn't booting.
For example one error might be bad blocks on the eMMC solid state drive. Or some driver on the USB bus. Or most likely the i2c code written in python (so you can read all the ultimaker written code including comments right on the UM3) is having trouble communicating with the print head.

Actually, watch this video before doing anything: https://ultimakernasupport.zendesk.com/hc/en-us/articles/115004226246-Printhead
Try powering up one more time.
