My 46" LCD model LN46A550P3FXZA has gone out. It was covered under the Samsung settlement to replace the power board and capacitors, however after they sent out some inept technicians to repair it, then suddenly the main board is bad. The main board of course is not covered in the settlement so instead of paying the inept techs $300 to replace the main board. I am trying to locate the main board to purchase and install myself. Any help would be appreciated.
