is there one for new LCD TV's

I bought new Toshiba 40XF355 which was delivered on Friday and gained one
hot pixel over the weekend.

I have asked the suppliers customer service to comment.

I notice it every time now.

I've never received a straight answer from a couple of manufacturers about
dead and stuck pixel policy.

I bought an LCD computer monitor about five years ago, that had a dead pixel,
the store made no fuss at all about replacing the monitor.

Where is the stuck pixel, near the centre, or near the edge ?

As far as I'm concerned, a dead pixel is a manufacturing defect, whatever
the company's policy states. If Sony (for example) said that CDs might jump
in a couple of places when played due to the way they're made, you wouldn't
accept that, even though they say it's within spec.

its 9" in from right 1.5" from the top,

Its clearly visible when on wide or letterbox and when darkish background on
other formats.

I know its only very small on such a large screen, but its like a pimple on
yer face.............you just know it's there and your eyes make for it all
the time.

From Googling it only seems to relate to PC displays, not ones for TV,
although the same principles should apply.

For pixel defects in broadcast TV cameras, a zone system is used, with
minimum, or in most cases zero tolerance of defects within a central circle.
Defects are allowed at the edges and corners. IS0 13406-2 doesn't seem to
apply that criteria ?

I agree , especially if this information isn't clearly conveyed to customers
before they make a purchase

Equally it's not a state secret, just a bit of research before a purchase

http://en.wikipedia.org/wiki/ISO_13406-2

Most manufacturers will specify Class II, so for a 1920x1080 pixel set,
that equals 4 dead pixels and 4 hot pixels and 10 stuck pixels (of which
4 could be adjacent) before it would be considered sub-standard.
