Does not boot after replace the HDD cable

Hi, everyone!

I was using my MBP 2010 booting from an external drive cause the HDD cable was broken, then two days ago I replaced the cable and now it doesn't boot. Everything makes noise running, but after 5sec the MPB turn off and then turn on again and continuing until I press SHIFT+CTRL+OPTION+POWER to turn it off.

I made a record: https://youtu.be/iocJlE1y-go

Can anyone help me, please?

At this point lets unplug the HD cable from the drive and see what it does. Do you here the Bong and get a flashing question mark on the folder on the screen?

I did it already and nothing happens. I also tried unplug the cable from logic board and it doesn't works.

By the way, the keys Q to O are not working, so I can't do NVRAM reset.
