Solved! My LG K30 won't Start

Dec 18, 2018
My LG K30 was working fine but then the phone started to overheat and I could not see the screen at all unless I held it at an angle in daylight. Afterwords I turned off the phone and opened the back but didn't see anything wrong. Thus I placed the cover back on and tried turning on my phone but it would not start or even charge when on it's charger. I have had this phone for 3 days and it already won't function.I have tried the above methods but nothing works. If anyone can help, It would be appreciated.
