Xblack and black spots

My VGN-S1XP has today developed two unusual black spots on the screen, one I found this afternoon, and the other has only appeared within the last few hours. But these are NOT dead pixels, the pixels are functioning correctly, and when viewed from different angles this is obvious.

The marks appear to be behind the pixels, at first when there was just one I wondered if an insect had found it's way in there. The other spot however, is decidedly not insect shaped! See attached picture.

Does anyone have any ideas as to what this might be? Could it be leaking liquid crystals? Would the pixels continue to function properly if this were the case? Or could it be some damage to the material behind the pixels?

Bear in mind this laptop has sat unused for about 24 months before I realised it only needed a new power switch connector.

 

that x-black technology means u'll get those marks

 

Is it a common problem with xblacks then? That's a bugger, because they look awesome.

 

no no am joking
u need to go to service centre if u have it in warranty ..

 

It's dust inside the screen, between the pixel layer and the film coating, caused by poor screen frame sealing.

It's common in some screens after ~3 years. It happened to my TR and SZ, but the TR had warranty and Sony replaced the screen for free.
It also happened to my old Dell 3007WFP-HC 30" monitor, and Dell gave me a 3008WFP in exchange for free

 

I very much doubt that it is still in warranty, unless Sony offer a really long warranty on their screens. I bough this laptop from eBaY over two years ago, and it wasn't new then. It does look like it could be something like that, although they are reasonably large areas, I would be surprised if dust accumulated just in those areas and nowhere else. Could it perhaps be a damaged coating? That would seem to make sense given the timings, left unused for ages, and then degraded with about a weeks worth of use? Could have taken that long for the light to remove the degraded area?

Either way it sounds like the sort of thing that is not user serviceable. (I'm handy with a soldering iron, and I've done a university course on Liquid Crystals, but I don't really fancy pulling it apart). A big shame because I really love this screen, and atm I can't really justify the money on a new laptop, and a replacement screen is about the same cost as the value of the laptop.

 

So If u have university done disassemble that display screen and look if something is not stuck there some rubbish

 

Depending on where you are, you may have law mandated reclamation rights that exceed the warranty of the product. Some countries dictate that flaws that shorten a reasonable and expected life span of a product must be fixed by the manufacturer at their expense, or otherwise compensated for, regardless of how long the warranty period is.

That said, two years seem to be the most common legal definition of "reasonable and expected life span" for consumer electronics, so it might not do you much good in this case.

 

That looks like a dead pixel.

 

mm , ebay is ebay ...
I bought mine aw11s/b from amazon in begining of december an till now works great
and i changed hdd disassembled replaced cpu ..
I managed dropped it from table (no big heigth) even ext hdd WD dropped too
and still laptop/hdd works

 

I developed a black spot a while back on my TZ's screen after one day transporting it naked in my backpack with some books on it which I'm sure caused it.

 

You do know that dead or stuck pixels can form weeks or even months later.

It is rare but it does happen.

 

In this case it is not dead pixels, I can see the pixels changing as I move different colours over them, it is something behind the pixels that is causing a shadow. I have a major deadline on Tuesday for which I need the laptop, but after then I may have a go at disassembling it to see what's what.
