Check the color wheel motor and around the motor circuits. Also check the
power supply for all proper voltages. R |

Does the Lamp actually ignite and iluminate the unit?? May also be the
ballast assembly for that lamp. Also may require replacment of complete light engine assembly. Light wheel has been a nusiance already on these. "RJ" wrote in message ... Check the color wheel motor and around the motor circuits. Also check the power supply for all proper voltages. R |

The Lamp itself lights. The screen is dark and there is no sound
regardless of input choice (Tuner or A/V). I do not know how to check the light wheel ... I have the documentation. Arthur Jernberg wrote: Does the Lamp actually ignite and iluminate the unit??

The MOTOR itself has a failure history. Your manual should go into detail
about how to troubleshoot . R |
