Samsung DLP HLR4266WX/XAA not turning on

Hi all,
When I turn on the TV with the controller, the lamp led flashes,
then goes off then flashes again and repeats a couple of times, then shuts down. The other two leds are off when the lamp led is flashing.
I replaced the lamp assembly and have the same problem.
I removed the color wheel assembly it spins freely not binding and the color glass is not shattered. Re-installed the color wheel assembly, removed the bulb assembly turned on the TV and noticed the color wheel is not spinning. I have 320VDC going to the ballast. I am assuming the problem might be due to a signal
not coming from the DMD board to the color wheel, and if the color wheel is not turning, the Ballast will not fire to turn on the bulb. Any help will be greatly appreciated.
