PUMPKIN CAR STEREO SUPPORT CENTER

Hello, after trying to install an update because part of my screen wasn't responsive anymore, almost at the end of the installation from the recovery mode my screen went dark and it is impossible to get it to turn on again.. I tried holding the power button and even the reset button but can't even get into recovery mode !
But I know it is still connected to the electricity because when I release the reset button , the other buttons flash just once very lightly.
Thanks for your help
