Console won’t turn on after replacing joycon sensor rails

So I followed the guide on this website for replacing the right joycon sensor rail on my switch (Remplazo del Riel del sensor del Joy Con derecho del Nintendo Switch), but now when I try to turn it on the Nintendo logo will pull up for a few seconds before going blank. Also, when I can only get the logo to show up after holding the power button down for 15+ seconds and then pressing it again. I am absolutely sure that I did not mess with anything else while doing the repairs. I am positive that the console has a full charge and just in case it is plugged in right now. I would appreciate any help I could get on this matter, as I don’t want to send it back to Nintendo to get it repaired. Thanks in advance!
