Urgent!

Was in the kitchen making food and the tv started making a high pitched loud hissing beeping ringing noise that sounded like an explosive device or an alarm I don’t know how to explain it. I ran and tried to turn it off with the remote and it wouldn’t turn off and the whole bottom portion of the screen was black and I unplugged it and I’m pretty sure it shocked me. I can’t describe to yall how fucking loud this noise was it threw me into a whole panic
