Problem with touch screen

[YanezDeGomera]

Good morning, I have a problem with my player. I don't know the name but is similar to the onda 858.
To the sudden one the screen doesn't respond to commands anymore any point I press.

I have tried to change firmware but the problem it remains. It results as lock.

Does someone have some idea?

Thanks

Is there a "reset" button somewhere on the casing of your player?

What about other buttons you can press instead? Does your player have any bottons or is it completely touch screen based?
