Switch black screen after injecting payload

Hi everyone. First of all, my first language is not English, so I will use Google translator to help me, sorry for possible mistakes.
I have a Switch bought several months ago and I had no problem with it until today. I connected my Switch to internet by mistake, and after that a message saying that a new system update is ready for install start appearing. I wanted to remove the message via Goldleaf, but since I don't have that program on my Switch, I turned off my console, remove the SD, plug it to my PC, copy the .nro to the switch folder of the SD, unplug the SD from my PC and plug it again to my Switch. Then, I plug the dongle and press the Power button, and the screen illuminates, the controls vibres but no signal, just a black screen. Then, I tried injecting the payload via Tegra and the same result. My console have 50% charge, so is not a battery problem. Any suggestions?

Don't use goldleaf, just enter to original recovery mode and that's it!

It's too late for that pal... Anyway, I realized that the screen actually works, I can touch it and it works, and it even sounds, but I can see nothing but a backlight. If I conect the Switch at the dock, it works properly, but if I try to play portable mode the screen remains black with blacklight. Any suggestions?
