Prius won’t start

I have changed both o2 sensors and coolant pump as the codes popped up on the cancer. Car drove fine and the AC that had stopped working started up again. I got home parked my car smoked with the air going and then my car just died. I go to turn it on and it flashed where the gear guage is and wouldn’t turn on but the ACC (radio lights etc) turned on. So I checked my fuses some 15a fuses were blown out new ones in changed my 12v battery and go to turn it on it turned on and flashed the gas guage and the transmition guage. It wouldn’t reverse just rolled forward. Turned it off and back on and just flashed and turned off again. Not sure what’s going on and I don’t wanna sell my baby just yet!!! And I also don’t want to spend 300$ to get a specialist to check the computer just to tell me something small is the issue. I’m 24 in the Bay Area living is rough and I’m trying to do this as cost effective as possible. The video I uploaded is the first flashing lights. Now it just flashed squares where the transmission guage lights are. If anyone can help that’d be awesome. Like maybe my coolant wasn’t bled enough or was put in wrong or something

 

I guess the video wouldn’t load. Go figure
