Mybe it's a noob question, but this happened to my Star Wars Trilogy cabinet's monitor:
It was turned on, my 6 years old nephew played with it and there was a short circuit somewhere in my house, so I have to switch back the fuses to bring back electricity.
When it started to work again, colours was very strange, a lot of them was turned to purple(yellows mostly)

Is it rubbish or could be fixed somehow?

Thanks in advance.
