This set has no sound when going through the RF connector, and the
video looks like there is short white horizomtal random lines similar
to electrical noise going through it. When going in through the video
input in either the front or the back though there is sound and the
picture looks the same. Would a bad SBX module cause no sound on
signals input through the RF connector and allow sound when going in
through the line inputs? And as far as the picture quality I suspected
the 1-464=756-21 VIF/ sound module (the 2.0" X 2.0" X .50" metal
module that I've seen go bad in the past). Although I've seen these
become intermittent and cause the picture to just fade out, could it
also cause this
"electrical noise" effect too? I have had success in resoldering
those but its very time consuming and I don't want to go that route
on a maybe. The customer said that he lost the sound through the RF
section some time ago and has been using the line input until I
suspect the picture through that became degraded as well. Does this
scenario sound like anything usual to anyone? Thanks, Lenny Stein,
