I have cable from the wall to a cable box then from the cable box "to tv". The "TV" is a projector that I was told required an RF modulator to convert from the coaxial cable. I have the cable box and RF modulator set to channel 3, all RGB cables plugged in correctly and the projector will not recognize any signal.
Tried just connecting my laptop with MVGA cables to test projector, wouldn't recognize that either. Any suggestions? The projector was used successfully on a daily basis with multiple hookups before I received it.
