Y stop > Pinda > Fail self Test > Now No power! (sad. help?)

Greetings All,
My Prusa i3 MK2 was running very well, but I've run into problems and it is now out of service.

1. a roll of filament fell on the Y motor mount, breaking off the piece holding the Y end stop plastic (back, centre of printer).

2. I put the printer on it's side to access the part, and glued it back together

3. A few days later, after glue had dried, I tried to run the calibration... The extruder was pushing down into the bed.. So I thought maybe there was a problem with Pinda?

4. I tried to run 'self test' and first, everything seemed OK.. Then it stopped after second fan

5. tried running self test again, this time failed on FIRST fan

6. tried rebooting machine, now is black -- no power!

I'm very sad.. my nice printer is sitting waiting for some printing action. Can anyone give me advice?

Should I first look at power? fuses? Is there a guide somewhere?

Thank you very much.
