- I received a 'new' (ie likely refurb'd) Playbook 32G late last week from RIM support, following an RMA on my old one for disintegrating trim. All seems perfect however there's one stuck green pixel close to the screen's centre.
Using the screen exerciser video on Youtube hasn't resolved the issue so I'm contemplating whether to make another call to support or living with it.
One weird point though: if I look at a website, for instance, with a black background I can see the pixel clearly. If I zoom in at all, however, it disappears. I thought stuck pixels were a hardware problem..? Anyone have an explanation for this kind of behaviour?
And what is RIM's policy on stuck pixels: do one or two fall within the norm, or are these "class 1" screens (yes I read the wikipedia entry) such that there's zero tolerance? I ask because I don't want to be unreasonable. If we're expected to live with a few stuck pixels then I won't complain. RIM support has been very responsive but frankly I'm tired of going back to them.

I took a couple of screenshots and the pixel doesn't appear in the pictures. At the same time, though, the pixel's colour seems to moderate depending on how close it is to other colours. If it's close to an icon on the home screen it's very bright green-white, but if I slide the screen so the pixel is in an empty field against the background it seems to get closer to the dominant colour in the image.
So it seems to be doing something, just not what it's supposed to do.

- Hi F2 -- I did download and run "Display Test" and "Screen Tester." Are these what you had in mind? Both provide full-screen monocolour slides to help identify misbehaving pixels but no diagnostics or repair processes that I can see.
Interestingly both apps show that this pixel displays a different colour depending on what background it's against (or I suppose what colour it's being asked to show). On yellow it's red; on green it's black; on blue it's light blue, on pink it's white. On red, light blue, pure white or pure black I can't see it so maybe it's functioning properly. Weird.

As it is coloured its a stuck pixel rather than dead but as F2 says if these programs don't help rim support will have to try some other things, maybe even a wipe and reload to try and fix.
One other thing, have you tried a reboot?01-06-13 03:40 PMLike 0

Stuck pixel vanishes on zoom?
