I think the picture board on your lcd is malfunctioning, that is why the image is distorting and since you said you cannot see anything, it means the picture board of your lcd has developed fault.
The best thing for you to do now is to take the lcd to a local repairer within your vicinity or any service center to help with the replacement of the picture board because the fault is not something you can fix yourself, in order not to complicate issues.
