I just got my refurbished Mits HC5000 on Tuesday (1/5/10) and I got it all installed and calibrated for my setup. The picture looks great and everything works. However, when I switch sources on my receiver (Onkyo TX-SR705) the projector shuts down with the power and status light blinking a pattern of colors. I referred to the owner's manual and based on the led pattern of the two lights, I come up with an "abnormal" condition and I should "contact the manufacturer". I tried using 3 different lengths of HDMI cables (20ft, 10ft, and 6ft) all with the same results. I also plugged the PS3 directly to the projector and it will do that shutdown thing when changing from the lenshift/focus screen back to the PS3. Has anyone else had this problem?
