I recently purchased a used projector and all in all I am very happy with its performance, BUT I am picky and have noticed one or two scrolling bars that cycle through my seven foot hockey game. These lines are most notably seen when the screen is black or white. I was told it might be a wiring issue, but am not sure of what to do or where to start to correct it. Your expertise and comments are appreciated. John

[QUOTE=LuvMy 4805|Dec 20, 2007 5:25:54 AM] Better late than never I guess. Just came across your post, but found the answer to your question on this websight, "The factory defaults on RGB gain and offset are all 50. The changes we made to color balance were as follows: red gain, 54; green gain, 48; blue gain, 53; red offset, 52, green offset, 48; blue offset, 50." That was taken from the 2004 review, I use these settings on my 4805. [/QUOTE] Can anyone tell me the service code for the InFocus SP4800 / X1 series? I am looking to calibrate it with my colorimeter, but am having difficulty locating the access code. Many thanks in advance. I can be PM'd at pat2580@comcast.net
