Only got my k750i yesterday and I notice a big white speck bang in the centre of my screen. Is there a way of telling if its dust or a dead pixel? I can still see it when the phone is turned off if thats any help.
If it is dust, is there an easy way of taking the screen cover off so that I can just blow or shoo it off?
I'm reluctant to send back the phone as its via 02 contract and the replacement could be just as bad or worse, they really are terrible. Plus, the second I got it, I flashed it with DaVinci which they probably won't be too pleased with.
In all i'm nut sure what to do apart from live with it and have it niggle away at me, like with my PSP (why is it only SONY products that have dead pixels? My LCD monitor has no dead pixels neither does my ds or my mum's nokia!) |

first,ive had 10 ericsson or sony ericsson phones and none of them have had dead pixels 
second, u say u can still see it when ur phone is turned off. well then that solves it. doesnt take much brain power to figure out that u either have dust or a scratch on ur screen !
third, that will teach u to think again before u go ahead and flash ur phone with davinci
and last but not least, its Sony ERICSSON. i dont care bout ur PSP , but this is sony ERICSSON were talkin about. not to hard, is it???

if its dust you are most likely not to see it when the screen's on. |

Yes, if it is a dead pixel it will change colour depending on what screen, i.e. sometimes may be black or cyan or pink. depends, if it is dust you won't notice it when the phone's on.

actually, a dead pixel will stay solid black, because it is not alive at all.. a STUCK pixel, will change color and be locked on one color.
since you can still see yours when your phone is off...
i'm suspecting it's just dust |

And moreover, a dead pixel goes white, because the normal non-energized status of a LCD cell is transparent, not opaque. So that the light from the lamp goes through and the pixel is white.
That is, if both three RGB components are dead.

The best way to check if it's dead pixel or not is to get some bright background, like enter new sms, then watch the screen and rotate phone to left/right or up/down and you will easilly see if spot is in the same level with the lcd or above it. (if it covers the same pixel all the time, it's pixel problem/ if it moves over different pixels while you're moving phone it's dirt)

In his case, it is a white spot. If he switches the phone off and the white spot is still there, then it is obviously dust or a scratch, don't you think?

the problem with this forum is that we have Too many ppl who Think theyre experts, when in reality they dont know what theyre talkin about !!!
seriously, it doesnt take more than an IQ of 80 to figure out that its Not a dead pixel since it cant be seen once the phone is OFF !!!!
ur either st***d or u have no knowledge whatsoever when it comes to displays !!! have u ever seen a dead pixel ??? well, let me inform u that u cant see it once the screen is off...
end of discussion, go learn a few things before u start posting b***s**t !!!
