Xperia ZL dropped and doesn't turn on, or it does, I don't know

After being dropped my Xperia ZL worked fine for some time, then, it turned off and now when I turn it on, it turns on normally, but when it gets to the home page, it turns off (not a power cut, it says "Shutting Down..."), already tried to remove the SIM Card and restore to factory settings both without any success (recovered with Xperia PC Companion, it recovered normally, but still has the same problem, expect it doesn't show the home screen, it shows the first setting after restoring the phone). I don't think it's the battery, it was working fine and the phone turns off normally instead of cutting power.

 

Additional info:

Battery was at 77% last time I've checked.

It shows it's charging if I plug in the charger, but even turning it on with the charger connected it doesn't work.

I can't open it because I don't have a small enough screwdriver

Battery is not removable.

Sounds like something on the logic board isn't too happy after you dropped it.

Still strange because it only turns off after the phone is already on, gave it another shot and for now it looks to be working (didn't do any other troubleshooting, just left it alone for a while). Doing the initial setup.

Nevermind, it was "Optimizing apps" for a while and after showing "Android is starting up" or something like that it turned back off and still in the same situation.

Yep something on the logic board isn't happy.

Just an update to this case, I tried Sony but they said they can't fix it because the phone is too old (even if they did it wouldn't be worth it), I took to a guy that fixes phones and it only worked for a few minutes after I took it home, he couldn't fix it again and refunded me. Today I remembered seeing a guy with a phone that took a bath in the toilet and he managed to fix it by washing the mobo with alcohol, I decided to try and it worked! Still working normally for some hours now and no problems whatsoever
