Hello Goodnight. The possible causes of protection can be many and varied ... From a short speaker to a damaged transistor. Please provide some more specific details. As an example, since when did it start with that ?? You were using it, it was turned off and when you turned it on you protected yourself ?? Did you suffer from any type of low voltage or over voltage network ?? Regards!

Well at first it was because of the sound like it was high volume and short and stopped listening and then grab but without the buffer and uncover and try to move where the video inputs (yellow, white and red) and That's where I got some sparks and protected myself.

Auch!
We could believe that the microprocessor (which would be the worst case) got damaged, but! There is a possibility that this is not the case, since they bring many types of protections to avoid that. Tell me something, did you see that it was what made sparks ?? Or any calcined component?
Another thing, you said that it hurt that you raise the volume, which gives the pattern of insufficient ventilation, which causes the power circuit to raise more temperature than allowed and cut to avoid damage.
One more.
Any particular message that shows on the display?
