Can anyone help me

My Motorized VGA Touchscreen has broken I think and I need to know what's gone wrong and how to fix it....

I have a K300 Motorized 7" Touchscreen and the right hand side of the screen is either not displaying the text, or comes up with loads of different vertical colours.

I know this is nothing to do with the PC as the PC isn't connected. This problem is happening on the menu screens.

Someone has sugguested it might be a ribbon? I don't know about this, so can anyone confirm or advise?

And does anyone know how'd I'd go about fixing it

Thanks
