Vertical white line appeared on display.

Hi,

On my Dell Studio 1749 a vertical white line has appeared about 3 inches in from the left hand side. It started off about 1mm wide but is gradually increasing in width and is now about 4mm wide. There is no problem on an external monitor when connected.

Is this likely to be a fault with the panel or a chip problem?

Any idea?

Please help.

Thanks!

I didn't find the right solution from the Internet.
