white lines on start up (image)

Good day,
With no reason, my macbookpro feezed yesterday. When rebooting, white lines on the screen appears right from the beggining, as in the image.
Any help around, please!!!!!
Thank you

Without any information about your MBP (year and model) and which version of OS X it's running, you're not going to get much help. What happens when you attach an external monitor to your MBP?

Thanks chscag

All the info is on the computer, but if I am not wrong, I bought it in july 2007, 15' display with 2.4GHz , 2gb of memory runing on Leopard.
I went here in Paris, France on 3 diferent Mac dealers for diagnosis, all said that most likely I would have to change the motherboard, with a cost around 600 euros. Uiii!!!.
Is that correct, on your point of view?
Thank you
Mauricio

I can't verify if the motherboard is bad (Logic board graphics chipset) unless you can test it by attaching an external monitor or TV. Do that and let me know what happens. If the external monitor or TV does the same thing, then the motherboard is bad and will probably be very expensive to repair.

ok, thanks, I will do that, and if this is the case, is it woth it to pay so much money or think about buying a new one

If it turns out to be a bad graphics chipset, it's not worth repairing. You will be better off buying a new machine.

thanks for the advice, take care.
