Samsung HL-T4675S BP96-01829A DMD Board

Replacing a DLP Chip or DMD Formatter Board can cause alignment issues with your display. Here are some tips to help reduce stress and time during your repair. If your TV has a safety switch, please be sure to tape it in the closed position, so that your TV can power on without having the back cover installed. A Samsung DLP TV typically has a linearity ring on the DMD Board. This piece adjusts the focus of your image. Mark where the tip of the arrow hits the ring prior to disassembly. Matching the arrow with your mark during reassembly will help maintain good image focus. For Mitsubishi and other DLP TVs that do not have a linearity ring, tape over the edges of the DMD Board and housing. Draw a straight line on each piece of tape, and cut along the edge of the DMD board with a razor blade. Remove the board, making sure not to remove any pieces of tape.
