I just bought an Onkyo sr701 receiver, but am having trouble with interference from my rf coax cable (cable tv). The interference / distortion is in the form of lines going from the top to the bottom of the screen, scrolling from right to left (it's not horrible distortion, but noticable)
Note the following: (1) There is no interference when I do not have the Onkyo receiver "monitor out" connected to my TV. (2) The interference still exists even if no rf signal is indirectly fed into the receiver (i.e. video feed from Tivo).
(3) When I unplug the cable signal from the wall, distortion goes away.
(4) I have no interference problems without the receiver.
Could this be a problem with the receiver, even though video signal is transmitted fine when no cable tv is connected (i.e. DVD works fine without cable connected, but when cable is connected, DVD has same distortion problem).
I have tried using different coax cables, bypassing all possible connections, etc - to no avail..
Anybody have an idea of what I should do next, or is the receiver faulty?
You did not say how you have this wired and so it is difficult to know how to respond.
Is there a cable box involved or just the rf cable from the wall to the tv?
Are you running video outs to the receiver FROM the tv and then back to the TV video IN's?
Assuming there is no cable box, then you would run cable in to the tv, and then audio out to the receiver.
Assuming also that you are using the receiver for switching, then you would wire everything into the receiver and then one video out to the tv using composite or s-vid.
Write back on how this is wired up and I think someone here can give you an idea what is happening.
The wiring is from wall to cable box, from cable box to TIVO (via regular coax cable wire), from Tivo to receiver (via S-Video and composite audio) and from receiver to TV via S-Video and composite audio.
