How do I distinguish if is broken the LCD or LVDS on MacBook Pro'07¿?

Hi everyone!

First of all thank you very much for your help.

I've been reading on ifixit on how to distinguish between LVDS error and inverter error, but not between LVDS and LCD error.

Since 1 year ago on my screen appears white horizontal lines, that they move on as I move the screen.

They used to disappear but since last month they don't.

Also it appears black rectangles, and they move on when I move the screen :S

I attach some pictures...

Thank you very much again and sorry for my bad english :S

The MBP 2007 A1226 has the infamous 8600 graphic card. First troubleshooting step would be to connect your computer to an external monitor and check if video is normal or not. If not then the graphic card is faulty.

Xavi, just like lemerise suggested, what do you see when you connect an external monitor? It was suggested that it is the video card but you have to do the diagnostics for that. Connect an external monitor.....

HI ! Yes I did it and worked perfectly with the external monitor!

I also disassembled to see if there was any bad connection but everything was perfect...

Xavi, since the external monitor works, it is not your video card. From your images it does appear to be a bad display assembly.

So I have to change the display data cable?

Thank you very much :)

I don't think it'll be the cable. From your description and images and having verified your GPU is ok, I put my money on the LCD. Of course, changing the cable is less expensive and would be a good step.
