When on, the only thing which will display on the screen is what can only be described as a still 'white noise'image such as you would get on a tv with no signal.
The screen lights up and goes dark, the player plays music etc as it should, although the screen seems locked onto this scrambled image. Reseting the unit makes no difference.
Any suggestions what might have happened of how to solve the problem please?

There's nothing switching the display. the back of the screen is usually a bank of white LEDs behind a diffuser or a white florescent flat tube. That is what you are seeing. In front of this is a layer with each pixel point represented by a blue red and green LCD cell.
When current is applied the structure of the LCD becomes amorphous and the light shining from behind lights up the pixel through a polarising screen.
If you can see the white backlight then some thing may have gone drastically wrong with the display. that's unusual because normally the display is all 'off' when the display is at rest (no current). So either your display/ video output is in serious trouble or it's another issue that I can't answer because there's not enough info.
You may need to take it to a repair technician to assess the situation in person.
Video issues like you describe can only be two things in hardware either a Video card, or display. Patchy display is typically a bad display that has been dropped or damaged. On the software side a new driver or update can cause image problems but typically it will be no display vs. patchy display.
It seem you have damaged part of screen where you hit the scale.
Do one thing try to disassemble screen and the re assemble screen and then check. It seem you have physically damaged your screen.
Better to use glass on your screen.

There is no fix, it is a Pixel gone out in display panel, good chance it is just stuck and will right itself but sadly sometimes they dont and the only fix is to replace the entire display panel Manufactures warrant such defects different depending on amount of dead pixels on screen is considered faulty, ie 3 pixels grouped or 5 separate ones .
