Hey guys, yesterday I left my phone to charge at night. in the morning phone was turned off and when I try to turn it on firstly i got bootloop four or five times but after it - red diode flashes three times and that's all. Sometimes it goes to SONY logo and turns off again. I can get to recovery (CyanogenMod Recovery) - my rom i CM 12.1 Ressurection Remix v 5.4.1. I have already tried all wipes and flashing ROM again but it doesn't do anything. I read that it can be broken charging module on motherboard. Is it true ? Is it possible to fix it by myself? HELP!

PS. Sorry for my bad english :/
