I have an Inspiron 8500. Recently, a black spot, really just non-illuminated, appeared about 3/4 an inch from the bottom of the display, approx. in the middle. It is very small, and 'in' the display. This is not a stain or mark on the outside of the display in any way. It seems like a 'dead' pixel.
It remains after reboot, and is visible in all applications and Safe Mode.
Is there anything I can do to fix this issue, which appears to be a problem with hardware? Or do I just need to call in and see about having it serviced?
One dead pixel will not qualify you for a replacement screen, which is the only way to fix a dead or stuck pixel.
The policies vary, but most vendors consider a screen serviceable if there are fewer than 5-10 dead pixels not clustered in the center - you can call, but you're likely going to be told you have to live with it.
Replacing the screen is a $500-700 fix - so unless you're willing to pay that, you're out of luck.
Thanks for your replies. This may be a common issue, but this is the frst time I've seen it on a laptop for many years (I used to service them quite a while ago). This is my 6 or 7th personal laptop, but the first Dell.
I'm going to be buying a subnotebook or tablet PC soon. Needless to say, it won't be a Dell.
Perhaps I've just been so lucky in not seeing dead pixels as to defy statistical probability.
But I doubt it. This almost certainly boils down to poor quality control and/or low quality part usage.
If they did replace the LCDs more often this would certainly give them incentive to make a less problem prone product.
I don't lower my standards simply because a manufacturer does. But thanks anyway.
No one will guarantee you no dead pixels. Would you be willing to pay 30% more for a system with a guarantee that there'd be no dead pixels? That's about what the cost increase would be if each maker had to toss all the screens with one or more dead pixels.
The technology isn't perfect - they're producing sheets of transistors - hundreds of thousands of them on a single panel - some are bound to have bad or stuck pixels.
And again, I'd say -- are you willing to pay 30% more for the guarantee of a perfect panel?
Most people would not -- which is why the standards are what they are.
It used to be that people had to accept some bad sectors on almost any new hard drive -- the bad sectors are still there, but now they're mapped out and hidden from the user. Unfortunately, there is no way to do that with an LCD panel.
