I have toshiba satellite p75-a7200, it will not start

It all started when I accidentally plugged in the laptop from the charger while the battery was closed. It just does not want to start the first attempt. Then i try to unplug it, hold down the power button for 1-3 minutes, nothing happens,
Yesterday, when I tried to power back my laptop, I found it did not start only the black screen tried the steps I did before, no luck.
I take it to someone to repair it. Please help me to turn it on, black screen and no backlight no Toshiba logo nothing, only the led laps shoving that it's powered on and that it's got power....

If you have greenlight on battery, and no boot, then you can try the battery trick.

please take a look: thank you!
