4. All other voltages turn on.
5. Digital PCB tells fans to turn on.
6. Digital PCB tells DMD PCB to turn color wheel on.
7. DMD / digital PCB’S check feedback signals from fans/ color wheel.
8. If OK, Digital PCB Tells ballast to turn lamp on. LAMP ON.
9. Digital PCB then checks “lamplitz signal” from ballast for status OK.

Background
Samsung introduced their new DLP technology projection televisions in 2002. DLP stands for
Digital Light Processing
DLP is quite different than conventional projection television, which uses three separate color CRT’s. These separate video signals are projected and combined on the screen. DLP, on the other hand, has no CRT’s. Instead, one high intensity lamp is used to project one image on the screen.
DLP technology was first developed by Texas Instruments.
The heart of this technology is the DMD, or
Digital Micromirror Device.
