I have a samsung pcl541R. I thought I was having a convergence problem so I ordered a new convergence board model AA41-00340C. I repalced the cards and (think) I reconnected all the wires as originally connected. I turned on the tv and the colors were better but seemed to pulsate. I attempted the auto focus with no luck and the tv shut itself off automatically after 90 seconds or so. I tried several times and was unable to get the screen to focus. I found some guidelines on resetting some memory using the remote and brought up a screen that looked like a giant checkerboard. I attempted to get out of this screen and now have perfect sound and no picture. Please help.
