I just change my laptop screen (New) and I only get a White Screen.
The laptop works fine with external monitor.
I believe the problem is in the ribbon cable.
So, where can I find the exactly one for my laptop and how to chang it.
Laptop: TOSHIBA P15 - S470.  
XP pro

Thanks for help.

The white screen indicates there is no video signal but you are getting power to the inverter to light the backlight. That could indicate either the screen controller on the back of the screen or the cable.
Are you using the old cable or is this the cable that came with the new screen?
I would try to reseat the cable on the motherboard first before changing.

Here is the disassembly guide for this model

If you have the cable of then look for a part number on it. You should be able to find it online through that number. You can post that number here also and I can look also.
does it look like this one.
