Vertical 1" thick bar on screen?

I've been using this laptop for a while. Acer 5672wlmi bought in May, used lightly, sent to Asia to my brother last month and now he's getting a approx. 1" thick vertical bar (from top to bottom) on the screen after the OS loads.

It remains still and located slightly left from the center. Has anyone ever encountered this issue? If so, what could cause this? Overheating? VGA malfunction, weather (moisture)?

I appreciate any input on this.

 

it hasnt happened to me it may have been from shipping (a good bang may have screwed it up) or maybe it is different frequencies having an effect on the lcd. i do not know what frequencies are used in asia as i have never been there so its just a guess.

 

Well, I have used it without any problem for few months. And this laptop runs on both 110/120/250V (US+Asia).

Perhaps, wire connection to LCD got loose internally. But the question is why doen't it appear until the windows finish loading the OS?

The Acer site is hard to navigate for solutions, I may have to call'em up. Until tehn, if anyone else has experienced this issue with any laptop, please share.

Thanks.

 

I read on another computer forum that something in the laptop is burning the cables in the LCD connection causing the wire to melt and giving that line. It is not going away. Its prettly much an "Ultra Dead Pixel."

 

That is very much possible, thanks for the info, I'll check. But how can I explain the fact that the line doesn't appear until after the OS is loaded. If wire is burning and causing that vertical dead pixel bar, it should appear as soon as the power is on!

 

have you tried reformatting windows? it might work...i mean if it doesnt happen til windows loads.

 

Is the pre-desktop area mostly back screen? If that is the case maybe it is hard to see?

 

Thank you for your input.
I was acquiring more info from my brother. He sent me a screenshot of the desktop, but the screenshot doesn't register the bar. So I guess it's a good news, that is, these are not dead pixels. Corrupted vga driver, or air bubble in the heatsink, or conflict with other drivers/devices.

What do you think?

Thanks.

 

It's a dead collum, as evidenced by the screenshot. It shows your entire graphics subsystem is just fine and that things go wrong after sending the data to the screen.

Bassically, you have a bad collum, collum driver or tab and your LCD subassembly must be replaced.
