Dead Pixel in Toshiba Porteg? M600 laptop

Good day! A couple of months back, I noticed a small black dot / dead pixel near the center of the LCD of my now 4-month old Toshiba Portegé M600-E360. Its color is black when viewed in front, but when I look sideways, its color is white. My supplier said industry standard for replacing laptops due to dead pixels is minimum of 5 dead pixels. So I'm stuck with it. I tried running a flashing program, but it didn't work. Is there any other way of fixing it? Any help will be greatly appreciated. Thanks!

Without rplacing the main part of the lcd, I'm afraid you're stuck.
Nice laptop. Toshiba service has always been reasonable in my experience.
Sorry I couldn't offer better advice.
Good luck

Dead pixel


It might, somes companies won't honour warranty unless you have 3 to 5 dead pixels. Go to www.samsung.com and contact customer support to see what can be done.

What does it mean by dead cells?


I assume this is related to your LCD monitor.
I think you mean dead pixels. The LCD monitor has tiny pixel elements, one for each red, blue, green color and each one of these colored pixels are turnes on by a transistor. When a transistor fails then the colored pixel it controls does not light up. This is a dead pixel and it shows up as a tiny black dot.
If the screen displays a blue screen, a dead blue pixel will appear as a tiny black dot in the blue screen.
You normally would not notice a few dead pixels unless they are grouped together.

Theres a black dot on the top right side wat can i do to fix it.


Is this a LCD and is it a very small dot ? If the answer is yes to both then it is a dead pixel (a white dot would be a shorted pixel). Most LCD makers wont do anything about this unless a certain number of pixels are bad. The only way to fix this is to replace the whole panel and that will probably cost more then a new tv.

My Ibm Laptop r51 has a vertical lines on the screen


The lines appearing on your LCD means it has a defect on the screen.

There are 3 types of pixel defect
1) dead pixel - pixel is always off
2) stuck pixel - pixel is always on
3) hot pixel - pixel is on but in red, green, blue or yellow, can also be a light black color

You can try to fix stuck or hot pixels but dead is dead.
1st method, flashing different colors rapidly:
JSScreenfix.com has a great tool. This is their free java applet or you can download it below.

2nd method, applying pressure to pixel:
Damp paper towel, Small stylus or dull pencil.

3rd method, tapping the pixel:
Pen with cover on or another small, blunt object.


If your laptop is still under warranty, get it replaced. If not you are looking at the most expensive part in a laptop to get replaced. (LCD screens on laptop is roughly equivalent to 40-60% of the total laptop cost

Please rate this if it this helps.

Dead pixel


Dead pixels cannot be fixed, each pixel is controlled by a transistor that is part of the LCD screen. If it is bad, the only option is to replace the LCD screen.

Yes i have a black dot on my new 2008 toshiba notebook.Do you know how to fix it.


If it is just one pixel that is black, you cannot do anything about it. It is what we call a "dead pixel". The best thing to do is to send it back in to the manufacturer and get a free replacement.

It's not the answer you wanted to hear, but again, there is nothing you can do about it.

Toshiba regza lcd 46x3500


This is what is known as a dead pixel. If you have a standard wide screen lcd monitor it has over 1 million pixels. It is not super un-common for one to go bad. It will either always be dark or in your case always be lit. It is not worth it to repair, and in most cases unless you have multiple dead pixels with in a square inch of screen, it is not covered under warranty either.
Each pixel is individual and the problem will most likely not spread.

Blackspot on screen


is it a tiny black dot? about one pixel? That is whats referred to as a dead pixel it happens on LCD nothing can be done of it but to replace the LCD screen. Usually you can just bare with it and wait til there are a few dead pixels before worrying about it.
Thanks,
Lee
