Question about Samsung HLP4663W 46" Rear Projection HDTV
I have the DLP TV
that won't turn on. Do you have an idea of what the supply voltage to
the color wheel should be? I am getting around 2.5 volts from the dmd
board. Does that sound about right? When I hold the door switch and try
to turn the tv on I can tell the color wheel does not spin.Oh by the
way the LEDs on the DMD board are lit up and there is voltage to the
ballast. Do think this would confirm the color wheel is bad?
Brandon. Locate CN110 on the DMD its a wire plug. Pin 2 is gorund pin 4 is voltage for the color wheel. When the color wheel is off pin 4 should have 5V on it when power is pressed it should have 7v for the color wheel to start. If the voltages on pin 4 is 5V your DM is ok and Color wheel would be indicated as faulty, But if pin 4 is anything less than 5V its the DM which is faulty.
