The phone does not turn on

@shajinali you are not giving us a lot to work with here. It would be nice to know what you have checked or what you have tried to fix it. Anyhow, first you want to check your power supply. Make sure it has the proper voltages. Check to make sure connectors are not bend etc. After that, check the charging port. Clean it of any debris etc, use a few puffs of air to clean it out. Check the DC-in jack of your laptop. Make sure there is no corrosion, debris etc. that prevents it from working. If none of this works, get an ammeter and see if your laptop draws any amperage from the charger. After that, you need to check and see if your motherboard even gets power. For that of course, you need to open it up.

I would follow the Samsung troubleshooting flowchart
