Toshiba Tecra 8100 Laptop - LCD Screen or Inverter Fault?

["Andy" <andy@xxxxxxxxx>]

Hi. My old Toshiba Tecra 8100 laptop has developed this fault with one 
whitish thin green line running vertically from top to bottom of screen on 
the right hand side near to the middle of the LCD Screen and I am trying to 
fathom out if this fault is to do with the LCD Screen itself or the Inverter 
module so I know what to replace.
I have already replace the laptop main board (due to a different fault) but 
the laptop screen still has this vertical line there. So its not the 
graphics chip at fault on the main board and also when I plug an external 
monitor into the VGA port the line doesn't appear on the external monitor.
Must be either Inverter or LCD Panel but which one????

A video of the fault I have uploaded here on youtube so you can see 
whereabouts it is and how the line looks like:

Thanks for any helpful advice.
