Hey im new to answering posts so hope this help.
Are there any lights that come on when you plug your charger in? If not try this
Remove your charger and battery and anything else you may have plugged in like sd card or usb devices
Hold the power button in for 10 seconds. You'll see nothing happen but this is just discharging the capacitors the mainboard.
Then plug your battery and charger in
Try turning on and see if it works. Is there any powee now or still no lights
If there is still no lights at all. Could be your charger or the power dc socket. googling showed can fail on theses
Let me know if this helpa
