Just had a 32inch standard (not LCD/Plasma) Toshiba widescreen delivered
this weekend. All seemed fine, but I switched it on this morning, and after
watching it for a bit, I noticed 3 dead pixels.

How common is this? Are there likely to be more die? To be honest, they're
not really that noticeable, but when I think about it, I look straight at
the area where one is, and will notice them! Especially on white back
grounds.

So is a TV worth taking back over 3 dead pixels? If it was small enough to
take back to the shop, then I'd think yes, but it's getting the day off
work, to wait for the delivery of another one!

What are peoples thoughts on this? Or am I being very fussy!?

And, the replacement may have 4 dead pixels and might have other problems.
For a CRT, they aren't actually pixels but probably a shadowmask dot. There
is a specifications for this.

Odds are that you will not even be able to get any kind of warranty or
exchange for a whole 3 dead pixels. Contact the manufacture about the
defective pixel policy on lcd screen.

Basically, no, it is not worth trying to take it back for only 3 dead
pixels. Manufacturing tolerance is many more bad pixels than just
three.

Odd, I've never seen dead pixels on a CRT, must be some debris in the
shadow mask, or holes that didn't get fully etched. It's very unlikely
for more to develop, if it doesn't bother you just leave it alone, if it
does, you may be able to return it but it might not be worth the effort.
Personally I think the dead pixels would drive me nuts if they're in the
center portion of the screen, around the edges or corners I wouldn't
care as much.

Are they clustered together? If so I would certainly make a fuss. In any
case check the return policy and warranty, Maybe OK to return without
invoking warranty. Of course the next one might be worse.

Never heard of dead pixels in a CRT. You sure you don't mean LCD? Or a
differnt symptom?
If the store won't take it back for a few bad pixels, will they take it
back if it's dead? If so, it may be time to commit electronic homicide
to get your set replaced

I used to see this occasionally in minor brand CRT monitors.

I have a Sears-Sanyo TV made in the 1970s whose Hitachi CRT is still
bright and sharp, but from day one it's shown a small white dot, about
1" from the right edge, whenever the screen is blue in that area. I
decided to ask Sears about this defect 12 years after the purchase, and
they issued a $50 refund check without protest.

shadow mask, or holes that didn't get fully etched. It's very unlikely for

There's one nearish to the middle, and a couple in the left area of the
screen. None are near each other. To be honest, you really don't notice
them. I was just concerned that more might go out. But I've learnt that
they're not actual pixels on CRT televisions! But like you said, just
holes - So like you said, it sounds like there won't be anymore!

One other thing I have noticed with my new TV is when viewing pictures, it
looks fine. But, if a light image comes into the picture, the whole screen
seems to darken down a touch. Not a lot, but if you're watching a moving
picture where something light is coming in and out of the picture fast (Like
someone walking down a corridor), the whole screen has a slight flickering
effect. Also, pressing the TV info button, to get the information banner up,
the sane thing happens. Like I said, it's very slight, but once you notice
it, it's annoying! Any ideas? It's something I can easily live with, but
I've not seen it on previous TV's I've had in the past!

My current set has two; one appears to be missing its phosphor, the other
is hard to see.

I got a service call years ago to replace a CRT on a brand-new set. This
one had one missing phosphor dot, *right in the center*. Any time a
person's face was in the middle of the screen, this pixel was a spot on
the person's nose.

How high is the contrast/picture set? Most TVs come from the store
with it set to maximum. At this setting, bright objects will overload
the power supply and cause the picture to dim, bend, or become blurry.
40-60% of maximum is usually about right. The TV will also last
longer with the picture at a reasonable level.

That one sounds like screen burn, I've seen it a few times when
deflection stopped but the beam was not killed immediately for one
reason or another.
