This is the most common problem with projection based sets, what you have is known as convergance failure. There are two Ic's and in a Samsung they are STK392-040's these will need to be replaced and possibly a small fuse and a few resistor. I am haveing trouble with the moidel number you gave and cant quite nail it down, but some Samsungs put these all on a easly replacable board. This board BP95-00142E is about $80.00 and avalible at www.vancebaldwin.com A easy way to tell is remove the back and see if these huge Ic's STK392-040 are mounted separly from everyother board and are mounted to the crt mount
