Initialization Process

Standby LED

1. Standby LED on Analog PCB ON (5V)

2. Power ON signal from Sub Front PCB or IR sensor to Digital PCB.

3. Power ON signal generated by Digital PCB-> Analog PCB-> POWER PCB.

4. All other voltages turn on (3 status LED’s on analog board lit) .

5. Fans turn on.

6. Fan protection circuit verifies Fan Operation.

7. Digital PCB tells DMD PCB to turn color wheel and lamp on.

8. DMD / digital PCB’s check feedback (LampLitz – low, DDP ready – High) signals from lamp and DMD Controller (DDP1011).

9. If OK, Digital PCB tells DMD to remove video mute.

Optical Section

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.
