Hi
I left My nokia lumia 520 (3 years old) in my bag for ~1 h after that i tried to turn it on an it dit nothing i tried to charge it and nothing again only a black screen
Please help
try this: Soft Reset is holding the Volume Down & Power buttons until the phone vibrates and reboots (about 10 seconds). This rebbots the phone with a cleared out RAM and Cache. No data is lost. It is good for when the phone freezes or you experience a glitch of some sort.
clean the contacts for the battery and in the phone too and then put the battery firmly back in and try switching on
If it doesn't switch on, connect with pc via USB and see if the pc detects it or not
The pc detects the phone bu in only makes a sound and the phones has no sign of life btw the battery contacts cant be cleaned and i also tried with another battery

then you may have to use windows device recovery tool to restore your phone OS - this is a software that you install on your pc and then you connect your phone to the pc and use it to restore the OS
