I bought a cable-tv (dvb-c) receiver and connected it to my projector with a 3meter hdmi cable. It worked fine for a couple of hours. and I switched it off. When I switched it on again, I received a "no signal" alert from the projector. I assumed the receiver was faulty and had it replaced. So far, I've tried three different dvb-c receivers, and the same thing happens each time. I know the projector is fine, since I regularly connect it to a dvd player, tablet or pc with the same cable.
I'm assuming that dvb-c receivers have a weaker output, so I'm considering using an hdmi booster / repeater. Does anyone know if that is the case? Thanks for any suggestions.
