Dell XPS Laptop screen problem - IMPORTANT UPDATE!
OK, I'm sure the model is irrelevant, but it's a Dell XPS M1330, about 3 years old and out of warranty.
About 3 days ago, the screen suddenly blanked, and on a power off/on reboot came up with a series of very thin vertical bars. After a couple of attempts I got it to reboot with a normal display but subsequently it has reverted to the above symptoms.
I think the screen is OK and would suggest that the screen controller has blown.
I welcome any views as to the problem and the likely cost of the fix.
Thanks
