tHIS is a convergence problem.. first question if you go into the customer setup menu. is the convergence option listed? If you have not got that option i suggest you read "the fl231 problem in the tips and trick section of this website. this can be a simple inexpensive repair..if you do have the convergence option then it can be one of three diffrent boards convergence power, convergence amp or small signal board. and will need further trouble shooting

Samsung 42" projection green and only green out of focus? Bulb? Tube? IC?
Just had new Ic?? Meaning single?? The symptoms you're describing are a convergence failure. That unit takes Stk392-040 Sanyo Ics and be aware there are a ton of Chineese knock-offs out there that can cause you real trouble, so purchase them from only a reputable part distributor... You need to change both amps, test all 3.9 ohm-2w resistors in that circuit, like Rz123 and Rz124 and check Fd102 3.5a pico fuse for open. That's actually a really easy set to work on for convergence problems because the entire convergence amp board is easily removed.
Good luck!
Bill
