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.

Cura 5.7 is here and it brings a handy new workflow improvement when using Thingiverse and Cura together, as well as additional capabilities for Method series printers, and a powerful way of sharing print settings using new printer-agnostic project files! Read on to find out about all of these improvements and more.
S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
(Sorry, was out of office when this released)
This update is for...
All UltiMaker S series
New features
Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

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