I have a weird problem with my Onkyo TX-SR603X receiver. The problem is that I get a picture loss for a few seconds while watching TV. Basically the picture goes black for about 5 second however the sound stays. The picture loss is very inconsistent. It happens sporadically and sometimes very frequently. I have a Pansat FTA satellite receiver connected to the Onkyo receiver via S video cable. Then from the Onkyo to the TV via component cables. I also tried using composite video cables from the Pansat to the Onkyo and same thing happens. I also replaced both cables(S video and component) and the issue also continues. On the other hand I have a DVD player connected via component to the Onkyo and then component to the TV. While watching from DVD i don't have the picture loss. I have not tested by connecting my DVD player via S video or composite to see if this issue would continue. I took the Onkyo receiver for repair and the repair service company has not been able to duplicate the problem. I am not sure anymore if it is my Onkyo receiver or the FTA receiver. Please help if anyone has an idea about this issue.
Sorry, I also forgot to mention that I connected the Pansat FTA satellite receiver directly to TV via S video and composite and the issue does not exist. I also tried changing from Video 1 to 2 to 3 on the Onkyo but the problem was there.
