Is it common for pixels to die on tv's?

[aphex]

I went to walmart (again) this evening to look at the 30" Sanyo Widescreen HDTV they have there and noticed a blotch of dead pixels in 3 different spots. Big enough i noticed it from 4-5 feet away.

Is that common? I've never seen it on tv's before.

crts don't get dead pixels.

What sort of TV? There are LCD tvs, and LCD projection TVs where it could occur...

Well that what was it? Looked exactly like dead bunches of pixels on an LCD monitor, except it was a HDTV CRT.

i've seen them on crts and prjection and lcd. i think it has something to do with the hdtv receiver more than anything...because i saw this once at best buy also.

None of the tv's around it had the same black spots though

were all the other tv's using an hdtv source? i think that sanyo has a built in hdtv tuner, so the tuner could have been buggy. in bestbuy, they have one hdtv source split up using an expensive high bandwith component video splitter (but sometimes the split signal is bad). I am wondering if it has more to do with the line doubler in the sets and no so much the hdtv reciever/decoder. next time try cycling the power on the tv.

All running off the same HD source using component inputs.

Yes, CRT's do get dead "pixels"

Of course CRT's do not have fixed pixels, in reality it's a dead area in the phosphor coating. My 19" CRT has two of them (quite small, & only noticeable against a pure white background).

There are no perfect display technologies, and an HDTV CRT is no more likely to develop it than any other CRT.
