I had a dead sub-pixel on my 32" Acer LCD Tv. it showed up on an all blue screen as one dead pixel. On other colours the pixel would be the incorrect colour, it depended on what colour was meant to be displayed as if it would be a problem or not.
I tried the "massage" method, and it worked, though not sure this is possible with an Imac... I gently massaged the pixel with a soft cloth, and miraculously it came to life. It would the generally stay on. Sometimes it would be off again when turning the TV on, but a quick massage, the slightest of touches would bring it back. Eventually it stayed working.
In the depth sof this winter (I've now had the TV over 12 months) it actually returned, but again just a massage brought it back, and in fact once I didn't do that and after the TV had warmed up it was again gone. It hasn't returned for a while.
Stuck is much worse than dead however. Can you return it?
