    I have tolerated a high pitched feedback whistle on my home cinema setup for too long, but now have a puppy!

    My Philips 28" widescreen is connected to my Philips DVD (LX8000SA) via TV audio output phono leads and a SCART on EXT2.

    If I cycle between EXT1 (freeview) to EXT2 I get a high pitched scream which is only stopped by pressing a DVD function, or continuing cycling to another source.

    I presume that sound is being sent back to the tv via the scart which is setting up some sort of loop

    If I remove the phonos, the feedback is gone BUT... cannot listen to freeview through 5.1 surround.

    An engineer (within warranty) changed the dvd connection from scart to composite video (?) into a tv scart adapter but the picture was substantially degraded which led me to switch back and tolerate burst ear drums.

    Is there a cabling config, or cabling components which will prevent this nasty feedback?
    :lease: Please help!!!

    So, you've connected the SCART output and 2 phono output on your DVD player to the SCART input and audio input on your tv ? The SCART already sends audio through that connection.

    How have you got the freeview connected and to where ? Has the tv got an integrated digital tuner ?

    Richie.

    Cheers Rich

    The setup was screaming b4 the freeview went on, so that's eliminated.

    The phonos are connected TV L&R OUT to DVD IN
    The scart is connected TV EXT2 to DVD (not sure about direct or bidirection)

    Yes the TV has a tuner, although I dont think that it is digital


    I previously had a normal aspect Philips TV connected to the DVD with no problem. That telly did not have a tuner

    Can you not connect the Freeview box's audio cable directly into the back of the DVD Surround instead of taking it from the TV ?

    Which TV have you got ?

    If you can't do the cables a Richie suggests you could try a RGB only (no audio) Scart cable. I just found out about these on another forum

    Here's a link to one: http://www.avland.co.uk/qed/sqartav41/index.htm

    Or, if you know which wires to cut....?
