Thousands of stuck pixels on NP8660..

Hi all!

I got a Sager 15" NP8660 in September last year. It has a matte display with a max resolution of 1920x1200.

Today after cleaning the display with a glass cleaner, I noticed thousands of stuck pixels on a black background. It looks like a galaxy of stars. They are tiny because of the resolution, yet noticable. There are literally stuck pixels all over the display. At least 10% of all pixels seem to be red, blue or green on a black background.

Do you think the cleaner fluid could have caused that? I noticed that they are mostly concentrated in the center of the display although I applied a little of the fluid on a napkin and went all over the display. The fluid is suitable for glass and also for TV Screens according to its description. Maybe the stuck pixels were already there before, but I just did not notice them cos of their size.

I already tried several tools like JScreenFix to fix them, yet none work so far. Is there anything I could do?

 

Well, the laptop doesn't have a glass screen. It looks like you've screwed your monitor. How about a picture to be sure.

 

The pixels are super tiny... really hard to see on a picture

Also I supposed there was some protective layer on the matte screen?

 

never use glass cleaner on any notebook screen.

 

Glass cleaner is way too strong for screen, the regular screen cleaner do provide some sort of protective layer, but still no match in front of glass cleaner.

 

The old fashioned way has always worked for me. Water and microfiber cloths from Walgreens can go a long way.

 

Might as well have used sandpaper.

 

like said above....

you have unfortunately damaged your LCD screen by improperly cleaning it with glass cleaner (ex. Windex).

you are supposed to clean it with microfiber cloth and some moisture... like water... or from a notebook screen cleaning product (which would be safe and be liable if it does damage your screen).

you will have to replace the LCD panel.

it will cost about $100-150 for a replacement LCD.

contact your vendor.

 

Have you ever used that cleaning solution before or was this the first time?

If he's used it in the past on occasion, it might be something else.

Too much pressure?
Fluid ran into the bottom?

 

I have never had a problem using windex or any other window cleaning product on an LCD screen (well I didnt use, my foreign parents did) He probably pushed down too hard or something else.

 

just google: windex and LCD

you will find that absolutely NO LCD manufacturer recommends cleaning the panels with any ammonia in it.

 

They don't recommend it, but I can't see it causing a suddenly display of bad pixels by its application to the screen, dead center no less, and not anyplace else.

With that being said, I use either off the shelf stuff for LCDs (since I'm lazy and don't want to mix my own) or basic water and a micro fibre cloth.

 

Most of the commercial LCD cleaners are a variant of the same ingredients:
~50% solution of isopropyl alcohol and ~50% water

Even the Apple manuals tells you to use a solution of diluted isopropyl alcohol, no more than a 50% solution

Windex (or any other ammonia based cleaner) will burn through the gloss or matte layer if used enough, and will cause burning onto the screen making it look like dead pixels or stuck bright pixels.

 

Glass cleaner is a big no no... A safe rule of thumb to live by is to use nothing but a dry or damp microfiber cloth with water only.
I don't see how this can be fixed other than buying a replacement screen.

 

I'd recommend using Optico Cleaning Wipe's. They say specifically on the cleaning wipe "Safely clean all eyewear including anti-reflective coated contact lenses, CDs, DVDs, LCD, Plasma screens and touchscreens on laptops, GPS screens, cell phones, cameras, PDAs and more." I have been using these since i got my first LCD sceen in 2003-4 and have never had a problem on any LCD since. Also you can buy about 100+ wipes from Costco for like 5 bucks. GG
