Bright patches (not bright spots?) on VPCZ1 FHD screen

Hey, so i got my screen replaced in November for bright spots so i do not think i have them again.
I have three patches of overly bright LCD/LED patches on the screen. They can be visibly seen on angles but still can be noticed normally. Its not that distracting but just that they are there...
Does anyone have any fixes for this or any explanations for why it might occur?
I'm still under warranty but the last time i sent it in to get my screen fixed, it took three weeks.

Any input would be appreciated.
Thanks

 

you mean dead pixels?

 

I think it's physically damaged and you should send it to Sony to get it repaired. under warranty.

 

it seems like they're just splotches on the screen.
So i guess the solution is to get sony =(
I guess i have to wait after my exams before i turn it in.

 

My VPCZ1 got the same bright patch too; I sent it to the sony service center and they replaced the whole lcd panel for me in 3 days for free

but I will need to pay extra to extend the warranty to 3 years because of this

 

They call this "bruising," and it looks like, I don't know, a skin disorder or something (or the reverse of what an actual skin bruise looks like - bright instead of dark blotches). Same problem on my FHD, but along with another repair, took over a month for Sony to fix, replacing the screen entirely. I think the best suggestion is to have a bullet-proof case for carrying, and always put a protective cloth between the keyboard and screen. Like so many laptops, since they were first made, this one has way too little of a gap between the keyboard and screen, and I'd bet that pressure from the keys or pressure on the backside of the screen leads to the bruising (although I don't know for sure).

 

Oh, so is this based on physical damage or the so-called "wear and tear". I generally use a silicone skin on the keyboard and then i put their cloth in between. I treat this laptop like a baby but the bulletproof case might be overkill for a student's needs xD.
This is my second screen problem with the sony z since i purchased it in November, i wonder what they'll say...

 

Make a fuss. AFAIC, this is a bad design flaw in the Z. They should not only fix these screens, but provide an actual solution to the problem, even if it means producing and providing a hard case for these models. I think anyone who carries the laptop around a lot will eventually have screen bruising unless the unit is very well protected, including the use of a hard shell case. I've carried other laptops for years without issue. The Z can't take normal use - needs to be really babied.

 

Both my work colleague's and my own VPCZ1 screen have developed this purple 'bruised' patch problem. His has multiple patches on the screen, whilst I have a single 1x1cm patch that is slowly enlarging.

Unfortunately my laptop is just past the warranty period and it is going to cost >$500 to have the screen replaced.

Sony needs to put out a general recall for this faulty laptop which we have all paid thousands for or if there are enough of us out there, push them with a class action.

 

From what I have seen, it appears the new Z2 FHD screen has a more refined antiglare coating. I have compare it to three other Z's (Z12 & Two Z13's) and have found that the visable grain is almost invisible now on the Z2.

Sony changed the part number a few months back, so perhaps there was a slight change.

That's also what I noticed.

 

I got this problem recently on my Z1 and yeah, its called bruising. Common causes are pressure on the screen, humidity and heat stress. You cannot fix it and it won't fix itself so don't even try. Mines out of warranty so I'm out of luck.

This used to be a common problem in macbooks (I do not know if it still is) but it can happen with any display. The thinner the lcd is, the more susceptible it will be to bruising, especially if it is not housed in a rigid enclosure. The keyboard may also exert pressure on the lcd if you put weight on the lid which is a design problem you are more likely to encounter in notebooks designed to be very slim.

I only had my Z1 for just over a week and it never left my keyboard stand, never had any weight put on the lid and I had a microfibre cloth on the keyboard when closed. I guess I just got unlucky.

 

This phenomenon, and it's explanations - especially the lack of adequate gap between keyboard and screen when the lid is closed - have popped up periodically on a thread and they just don't apply to my current Z11, nor to at least one other Z11 and one Z13 I'd owned and traveled with - all have 900p screens, in case that matters at all. What I see when I look at my present Z11 is that both the palm rests and the spacers located both on the outer edges of the keyboard deck and on either side of the screen bezel all working together, make it nearly impossible for the keys to push against the screen. I have to put quite a bit of force squarely on the middle of the closed lid to get the middle keys to barely touch the screen. whenever I transport the Z it is in a vertical position inside a neoprene reinforced case, and even when my bag or briefcase is packed tightly, there is not nearly enough pressure going horizontally to both bend the neoprene case, then put pressure on the Z's closed lid, and further push past the spacers as noted above.

Just leaves me wondering why some people experience this problem fairly immediately in the life of their Z and, as some of you feel, inevitably will damage all Z1 screens in time. Still, I do not want to be cavalier and believe that I have "superior spacers," lol, so I would appreciate it if someone could tell me how, by transporting it in the manner I describe above, is it really possible for enough horizontal pressure could be produced to cause the lid to be compressed against the keyboard when the computer is essentially resting on it's barrel hinge and standing upright, with both a cushion-y layer inside the neoprene sleeve and a decent amount of hardness on the external sides of the sleeve. Also, can you describe what happens at the places where the spacers on the lid and keyboard deck, and the palm rests, when your lid is closed. Do the spacers and palm rests on yours not create any "buffer" at all between the screen and keyboard?

Finally, since I've read about this from time to time, but not in the numbers most of the chronic design flaws of the Z are reported, could it really be that for units that have this problem, there truly is a manufacturing defect in which the spacers are pushed in too much and/or the lid mis-mounted on the hinge so that only in relatively rare cases did the Z1 come off the line with all these misalignments? It sounds like this could be the case, in which case I would strongly encourage anyone still under warranty of any kind to insist on not just a new screen, but sufficient replacement of such things as the bezel, keyboard deck, even lid, so that everything is properly aligned for the future.

My heart goes out to you for experiencing this; it would make me really angry too, and we all know how rarely Sony excepts the blame for anything that goes wrong with their products, especially when it leads to physical damage, which they immediately blame on "user mishandling." Good luck.
