i have a barco 600 tha the image is from the dvd and the satellite receiver, i have a composite video cable connected to the 400rvcd, which in turn is connected through rgbs to the barco. the test pattern doesn't show the flickering but video will. to make matter worst, i thought it was a connection problem but is not two days ago i turned the projector on and it was fine, fifteen minutes late it started with the flickering again, please can someone give an idea. i heard that curt is the guy to talk to, i hope he reads this threat.
