B650 Bricked After Update

[yasproject]

Hello friends
I have a B650 TV, after updating v2006 to version 3000, unfortunately the TV does not turn on and only the sound of the logo is heard, and after a few seconds the same action is repeated.
It doesn't even turn off and the same thing happens after connecting the power cable, please guide me to Unbrick my TV.
Thanks

Have you tried turning on the TV by holding down the channel increase button while trying to turn it on?

Yes, I tried it and it had no effect. In fact, when I connect the power cable, the TV turns on automatically and only its sound is heard. It has a light for a second and doesn't display any image, then it restarts and repeats the process.
