Hi, sad to report my PPM is also showing issues with no light from the lamp on startup. Had been working fine since I first received the unit ( about 4 days ) I also managed to apply recent firmware upgrade which looked like a big improvement on fan noise and user interface.
I have unplugged all devices and cables and the unit behaves in the same way as video uploaded by @ViktorM. Unit displays solid blue light, hear fan noise & auto focus noises.
EDIT: have managed to bring lamp back to life. I shook the unit very lightly and pressed the power button, and now we have light projection. I did spot some blurred vertical stripes on display briefly but after a few auto focus operations display appears ok.
Will keep a watch on this issue but fear I need to return unit soon.
