Question about Sony KP-57WV600 57" Rear Projection HDTV-Ready Television

1 Answer

Audio problems - great picture -fuzzy sound

Digital Sony tv 46in. Sometimes sound is good sometimes fuzzy or not a sharp sound. Plugged into an amp and than to speakers--makes no
difference. One dish two sets--Sony is hi def set. Cable runs from dish about 30 feet to tv set--cable outside for about 10 years. Sound better during the day than at night usually and better in warm weather than cold I think. Any ideas would be appreciated--have been thinking about a signal
booster but for the fact the picture is so good. Thankyou John Evans

    due to the line being up and running under a gutter I am not wild about replacing the line if the problem can be solved any other way.

Yes..that would make sense..the cable is getting dried out, and has less conductivity when it's hot or warm..that's not unusual

    actually, the brittleness factor is worse when it's cold, the conductivity is higher when the conductors are warmed up..
    I suggest you run a fresh cable in parallel to your dish, and see how that comes out.

    the primary component coming in from the dish through the cable is video, obviously,and audio runs under that signal, or along extra conductor.. in most cases, depending on your cable, the video runs on skin of conductor(called skin effect in fact) and the audio runs down the center. so impedance would hit the sound signal, more noticeably

    i got that..but it's worth a test with a fresh cable...those are usually not that good that long, really?

    what part of world are you in?

Red stand by light blinks 8 or 9 times and no picture or sound


hello Problem with the audio (AUDIO), unit goes to standby and blinks the self-diagnosis code. Check IC406 audio amp, PS401, and 402. On some projection models of Sony TV sets, this code means that T8005 (flyback transformer), or the associative components in the high voltage circuits are defective on the D board.Nine blinks - Replace D 6116 and D 6301 on the "G" board, do not resolder as this will fix the problem temporary. Or Panel Module Error or Thermal Error. If it is intermittent 9 blinks, meaning sometimes the TV comes on and other times you get flashing, then change the switching regulator on the "G" board or check connections. Make sure the regulator is -12 or -13 (negitive).
