Blade 14 2016 No video output

Hi, i'm having a big problem with my laptop, it's a razer blade 14 2016 the model with GTX 970m and Touch screen, my battery was bad it doesn't last more than half hour but i wasn't able to change it and earlier this week i turn on the laptop without plugging AC adapter just with the battery and the real problem started, it turned off because of the bad battery and when i plug the ac adapter and tried to turn it on it appears to turn on because the front right led was blinking green and the logo in the back on the screen was lighted too but i had no video signal the laptop screen doesn't turn on neither keyboard lighting and if i connect it to and external monitor trough HDMI there was no video signal, i have tried with the battery connected and disconnected and same happens, does anyone have an advise? what should i do? the laptop should work without the battery or i need to connect another battery to test if it works? how could i know if the battery damaged something else? any help is appreciate
