I have a Sanyo 21N with about 15 hours on it. I did not see anything like a dead pixel on the unit when new. I have had it a couple of weeks and I have noticed a few pixels which appear to be turned on when they are supposed to be black. They seem to be pixels and not dust. A few are red and is green. I hooked up my computer and ran an LCD test program which throws up a full raster of R,G,B,white,black. I cannot see these "stuck pixels" unless I send black. They seem to be able to turn on in response to other colors but not turn off. They all seem to be in the portion of the panel which falls on the un used portion when in the widescreen mode. I am wondering if forcing them to black takes a toll on the pixels? Will more fail??
