stuck pixels

Posted by: wal riley on 24 July 2007

Hi folks!
Just after a bit of advice. About 4 weeks ago I purchased a Samsung R87 series 32" lcd screen and i'm well happy with the picture quality of it. However, i seem to be getting blocks of stuck pixels in the same 2-3 square inches of the screen with some regularity. They are visible from across the room and - not being completely up to speed with LCD technology - i am not sure whether this is an artefact that i should expect with these screens or whether it is a proper manufacturing defect. John Lewis have agreed to replace it, but am i likely to be facing the same problem with the new screen?

I haven't noticed it on dvd. Having said that, I haven't watched that much on DVD to tell, seeing as the wife is a soap/big brother fanatic! They do appear regularly on cable, though and they can take anything up to 40 mins to correct themselves.

Is there a Samsung/LCD forum you can enquire on?
Google the model number that usually picks up forum replies if you sift through the ads.
The comparing sites Kelkoo etc. quite often have customer comments.You will find them amongst that previous Google too.

40 minutes to fix itself? Sounds like a fault to me...

John Lewis are doing a straight swap tommorow so, hopefully, it is just a one-off, but we shall see...
thanks everyone!

Run it low? That's news to me! Admittedly, until recently, all i'd ever owned were 4:3 crt screens and, to be honest, my first love is music so i'm a bit green to all of this. Therefore, if anyone else has any suggestions to running an LCD safely, i'm open to suggestions!

When you get the new one dont forget to run it in on low everything.Ie go into your menu and turn Bright/Con/and run on cool if you can for a few weeks.


This shouldn't be necessary with LCD displays, but is a must-do with plasmas–recent conversations suggest that an extended white-field burn-in is highly desirable for new, out-of-box plasma displays, prior to installation and calibration.

WHY PLEASE....?

My understanding is that it takes anything up to 2 months' use for a plasma to settle to its regular output. We have been advised by an ISF-trained engineer that any calibration should be done after the panel has been installed for a couple of months and that setting up the panel when new is suboptimal for this reason. A white sweep burn-in should accelerate the process.

I'm told by colleagues that ISF calibration really makes a big difference to pretty much any panel. The unfortunate thing is it costs around £300 to get an ISF-trained person to do the job. ISF training is expensive and calibration requires ISF approved equipment.

Doh!!!!
I got the replacement telly. First day's viewing was fine (but mainly dvds for a change). Put the telly on this morning - Stuck Pixels! Give or take an inch or two they were in the same area as the last telly, and they stayed regardless of channel. However, switched immediately to the dvd player and they disappeared! Switched back to the old V+ and they're back again! Firstly:
1)sorry Mr John Lewis sir, and
2)What the hell is going on?!!
Faulty lead, faulty V+ box or bad signal from Virgin media?
Any clues, anyone?
Sod it, i'm turning the music back on!!!!
