Screen covered with green and blue pixels (visible on dark colors)

Hello,


I have this tablet since beginning of April, and since few days I've noticed the little dots on the top of the screen.


From far away it looks like dust behind the screen, but by having a closer look, it's like pixels that stay green and blue when the rest of the image is dark.

It's very visible when I'm using the tablet with no lights around me.

 

i've tried to restart the tablet, and even when It's loading with the SONY sign, I have that!

 

what should I do ? Did people had that issue before ?

 

 


(BTW, The screen is also unresponsive when plugged to charge)

Re: Screen issue when black

Ive not seen that issue before but i currently have an issue where the screen wont respond to touch when waking, but thats a seperate issue.

Hi sebsmax and welcome to the community! Since you're new please be sure that you have checked out our Discussion guidelines.

 

In this case as it is almost certainly a hardware issue I would advise speaking with your local Xperia Care team to arrange an assessment of your device.

Re: Screen issue when black

Hello Sam,

 

I've bought my tablet on the official website of Sony with an extended warranty....


Despite the fact that I have to do everything by myself, like contacting the company that is dealing with the reparation...and sending the tablet in another country so it gets repaired. They can't tell me when I'll get it back and if it will be taken in the warranty.

 

I'll have to pay the transportation and won't get reimbursed for it!


So that's why I wanted to check before if it was a common issue with the screen, and if it was a hardware issue or a software issue. I'm using that tablet to develop games on it, so I can't afford to not to have it for months.

 

I was very happy with it, but having the screen covered with little dots after 4 months of use... it's quite disappointing!

If he doesn't have touchscreen issue from the start, he probably will not get them later either.

 

Try not to smear out the touch screen issues too much on the internet, if the sales flop later on, Sony might drop support and updates for the device prematurally like they did with the Acro S and some other handsets

Re: Screen issue when black

I have encountered this problem with my Xperia Z2 Tablet (SGP512, 32GB/WiFi, running Build 17.1.1.A.0.402), too. The blue and green pixels sprinkled all over the screen can only be seen when a black or dark coloured background is enabled and the environment is dark, too, but nevertheless it's quite annoying.

Moreover the screen looks really yellowish in comparison with the one of my Xperia M (with white balance on default settings or even with blue turned up to 50 or 75 points). And if that isn't enough there seems to be a smudgy yellow veil around the rim of the screen, which can be seen when the there's a light background, e.g. inside the settings (then you can moreover see two yellow spots in the bottom left corner since the navigation bar turns from black to a light grey), applications with light background or the homescreen with default Xperia theme enabled. I've bought the tablet in March this year but cannot say, whether this problems are new or whether I just haven't noticed them until now.

Re: Screen covered with green and blue pixels (visible on dark colors)

I have the same problem although mine is less visible, mostly during dark backgrounds.

 

Sent mine on service and they sent it back doing nothing, except claming that they did a software upgrade (which is a lie since I did it before I sent it in). 

 

Called Xperia Support again and this will probably result in that I have to send it in again. Blah.
