Bad pixels :( - Xperia Z4 Tablet Q&A, Help & Troubleshooting

Anyone with new tablet also had some defective pixels?
I´ve 6 pixels in blue and red, hard to see but they are there...it´s se second device, first had a defective flap.
Hard to believe but i think i´ve no luck with such devices...
What do you think? Give a third device a trie or remain on that device and ignore the pixelgate ?

You've answered your own question. They're hard to see, so it's not a real problem. Ignore it and stop needlessly returning devices, raising the cost of the product for all of us.

vertical coloured lines on screen

Hi
I was playing a game downloaded from handago.com, when my xda gave warning " too low on storage memory, and very quickly the screen filled up with vertical coloured lines. Now I can't see anythign on screen but those coloured lines. I have tried hard and soft reset but no use. Any help will be appreciated.
I too had this problem. I tried everything. But it seemed to be a hardware problem. In the end I had to send my XDA to o2 who replaced it. Sorry this is not very positive.

I really don´t think so, that was his/her only one post in the forum dated 2003
Do U have the solution
Brother If you have any solution let me know, I have shown the device to technicians , but they are not able to rectify the problem, some say it's LCD fault , few says it is a display IC .

Is it just bad luck or something else?

I had to return my g tablet to office depot for having 3 dead pixels. And now the replacement has about 5 dead pixels. Out of the box they were fine. But after using them for about 2 days the dead pixels happen. Both times I was running vegan gingerbread. Also none of them came with screen protectors. So is this just bad luck or something else?
certainly bad luck.
Non of the newer stock has any screen protectors (was confusing owners into thinking they got a faulty screen).
If the dead pixels were newly developed, did you try some of the online dead pixel re-activation applications ? Jscreen fix is one of them but requires java to run so not sure if it would run on the gtab.

How do you find these dead pixels? As the gtab is using a standard mass produced netbook screen, you would think dead pixels would be unlikely. I don't notice any on mine, but then again I haven't really checked each pixel.
I dont look for them, I just notice little black spots on the screen then go to wipe it off but come to find out its the actually screen. Then I get a pixel detecter from the market and then find about 5 others.

You sure you're not just seeing the digitizer substrate?
No, I see the the others dots that are in rows. I just took the second one back to office depot and the tech looked at it and confirmed that they were dead pixels. My next one is getting here Wednesday so hopefully the 3rd one is ok.
Would the software have anything to do with it? Because it seems like when I install Gingerbread they show up.
Quit installing gingerbread

Why? Could it actually mess with some display thing? I might just install vegan 5.1.1 and give it a few days then install gingerbread and see what happens.
Crumbs get under the screen... ;-)

I guess it wasn't as funny as I thought...
The ROM you install is not likely to be causing bad pixels. Bad pixels happen because manufacturers can't test every component with driving cost up so they ship the items and leave it to the customer to be final quality control. When buying at the low end of the cost spectrum you can expect more defects. The overwhelming majority of people won't even notice a few bad pixels or at least won't care and the manufacturers know that so it's cheaper for them to deal with the few people who do care through customer service than to fix the problem with higher cost parts.

No the rom would not be causing dead pixels. You sound half convinced of this so I figured you should just not install gingerbread anymore.
Maybe take it back and get an iPad

Are you working on commission?
I wouldn't care if they were just 1 pixel. But its at least 6 dead pixels grouped together and other black dots all of the screen. Ill install gingerbread again and it it happens again Im not going to exchange it at office depot. I will call viewsonic and get them to exchange it.

I'm quite sure you're NOT seeing dead pixels. Just return it, because every one you get is going to look that way. Unless someone drop-kicked it at office depot, of course, that would never pass the electronic inspection at the factory where the panels are made.
And no, the rom/os type won't make any difference.
Return it for a refund, and get something with a different style of LCD.

I am seeing them. The tablets don't come that, they get them about after 2 days. Every time the tech at office depot says its dead pixels and confirms that I can exchange it. I think they just have a bad batch of the ones they stocked their shelves with. They ordered the one thats coming tomorrow so hopefully it is going to be ok. Like I said before, If it happens again, I am sending it to viewsonic.

Well, that's even more odd. I have NEVER heard of an LCD developing dead pixels days later. Ever.
Good luck with it, whatever it is.

Bad pixel on my Galaxy Ace

After month of using Ace I found bad pixel on my screen
What's even worst is that it's in the middle of the screen and I can see it all the time. Did install Dead Pixel Detect to confirm this and unfortunately it is there.
Does anyone know if repair center will give me new one or at least change the screen on this one?
It depense of your warranty... But for me, I know that they will give me a new one if I have this problem.

I'll contact my warranty service and ask them about it, but I'm worried that they might want to change the screen and I don't want that.
After they changed screen and digitizer in my i900(I had white dot from overheating and poor digitizer - common problems with i900) it had specks of dust between the screen and the touch layer.
Hopefully they will give me new one. I'll keep you posted on my situation, maybe it'll be helpful to some

Dead Pixels

Has anybody experienced a dead pixel on their Sony Tablet S?
I have 1, not a big deal, but when you spend £400 on a device, you become very aware of it and you do not expect it to happen after a few days of buying it.
Im just seeing if anybody else is in the same boat, and if so, what they did about it?
Haven't exclusively looked, but I normally notice that sort of thing
I'd take it back, it's a genuine manufacturing defect. If they give you some BS about repairing just say you want a straight refund then buy another one, that's what happened with my Dell Streak.

Thanks for the advice. I was going to pop to the store tonight and see what they say, but I know some stores can be a bit funny about things like that.
Aren't a certain amount of dead pixels considered ok though?

Not when you spend a large sum of money on a tablet it isnt.
Anyway, managed to swap it it this evening thanks
Had that issue too....exchanged it for a new one..so far so good..weird thing was though, before I returned the one with the dead pixel, I did a factory restore to wipe all my info. After that the pixel was fine lol Still, didnt want to take the chance and just exchanged it.
Did you tell them you had issues with pixels or did you make something up to exchange it?
I told them it was a pixel issue...The guy turned it on, and like I said, it didn't show up because of the factory reset. I told the guy that I didnt want to take a chance and they gave me a new one.
No dead pixels here and havent seen any on a device in a few years. This is 2011. It shouldnt happen.

Weird light bleed

Anyone else have this issue.
The light is above the left capacitive button.
I've just had the device delivered, so is this a defective unit or are they all like this?
Thanks in advance

Is this a common problem or is it rare?
I'm asking because if it is a common problem, then I will get a refund and get something else.
Mine doesnt have this...this happens on all devices, just not good quality control, so wouldnt know how many are affected, luckily mine came perfect

Guess I'll have to get something else then. Now to contact the supplier and go from there.
BTW is it possible to check if the item is new or refurbished?
Rn3 is definetely new, its not old device...
It would be pretty hard to port MIUI on some other chipset

I don't think I made my self clear.
Do you think the item I received was a returned item, refurbished by the seller and then sold to me? If it was, is it possible to check? It looks like brand new to me.
I dont have the bleeding issue. I think the device got faulty screen and you might want to send to warranty for screen fix.
China phone is always like that either you received good phone or defect phone. There is no quality control in China company.

Thanks. I've contacted the seller, and I'll see what happens.
Though it looks like I'll be shipping it back to China.
