I also have the vertical stripe on the right side, but I made a special pair of glasses which are slightly darker on the left to counteract it. I tried making a pair of contacts to do the same, but apparently the ink from the Sharpie wasn't dry, and now the whites of my eyes are now a little gray.
In other news, I'm revisiting this thread because I'm having a very strange problem with the ol' 32" Sceptre. In the past week or two, this problem has happened three times, with no obvious trigger: The screen very suddenly gets dark, and colors start to shift (Ever seen the plasma effect use in demoscene back in the 90's? Yeah, didn't think so...). You can still make out some of the picture, but it's really freaky. The first couple of times, it went away by itself after about a minute. The last time it happened, yesterday, it went on for a few minutes before I turned the TV off and back on (via the remote - no need to pull the AC). But before the power cycle, I switched inputs, but no change -- even the TV's OSD was screwy. The TV is in a well ventilated, air-conditioned area, attached to a UPS.
Has anyone seen this happen before? I can live with it happening once in a while, but I don't want it to be a sign of a failure waiting to happen, especially being out of warranty and all.
