Yesterday I found dead pixel in my Acer Aspire 4710 !!! if you want to test your LCD download Dead Pixel Buddy (Download here)
I want to replace the LCD screen, but Acer Limited Warranty says :
minor defects of LCD displays occurring in Products equipped with LCD displayand my dead (defective) pixel just one pixel...
technology, provided that there shall not be more than four (4) defective pixels per
million pixels on a given LCD display, and provided further that, if the display panel
is divided into nine (9) equal rectangular areas, there shall be one defective pixel in the central area of the display.
Dead Pixel BuddyIf your dead pixel more than 4 pixels, goto Acer Service Center and they will replace your LCD with brand new LCD without dead/defective pixel
There are several ways to fix dead/defective pixel :
1. open this site and click "Launch JScreenFix"
and it will open JScreenFix Applet, The JScreenFix Java applet helps fix stuck pixels and image persistence on LCD screens and reduces burn-in on plasma screens. The applet runs safely inside a web browser, does not require installation and works with Windows, Linux and Mac computers. JScreenFix repairs most stuck pixels in under 20 minutes, and mild screen burn-in within 12 hours.
You can maximize the window then press F11 to enter Fullscreen (Firefox and IE)... or just drag the window to the dead pixel... another good site about fix dead pixel on LCD click here, or you can download this gif image (download here) open it and drag to your dead pixel to fix it
2. Pressure Method
- Turn off your computer's monitor.
- Get yourself a damp washcloth, so that you don't scratch your screen.
- Take a household pen, pencil, screwdriver, or some other sort of instrument with a focused, but relatively dull, point. A very good tool would be a PDA stylus.
- Fold the washcloth to make sure you don't accidentally puncture it and scratch the screen.
- Apply pressure through the folded washcloth with the instrument to exactly where the stuck pixel is. Try not to put pressure anywhere else, as this may make more stuck pixels.
- While applying pressure, turn on your computer and screen.
- Remove pressure and the stuck pixel should be gone. This works as the liquid in the liquid crystal has not spread into each little pixel. This liquid is used with the backlight on your monitor, allowing different amounts of light through, which creates the different colors.
Good luck ...
Oh, wow - I had no idea it was possible to bring dead pixels back to life! Thanks for posting this article.
ReplyDeleteThe Letterchamp has worked directly with manufacturers to replace defective computers - but this is definitely a good method to try before resorting to dealing with customer service people. Of course, the Letterchamp deals with customer service so you don't have to!
Thanks again for the great post! :)

ReplyDeleteBecause a laptop is pretty compact, some of the recent technology that's been developed for desktops has yet to be made into thinner and smaller forms and successfully fitted into laptops. So laptops are always a step behind desktops when it comes to capability and efficiency. However, the laptop market is growing and this situation is fast changing.
