Hi Ernie,
The SBX sound module was indeed my problem. The customer even told me
to not bother fixing the sound because he used a separate stereo for the
sound. How did you finally decide to change the SBX even though you
hadn't fixed the video problem? I would have done as you did. I would
have tried to fix the video before I tackled the sound problem as you
can still use the TV without sound, but not without picture. Thank you
for your post as I would have spent days on it. I guess it pays to fix
unrelated problems that we know how to fix, first--to eliminate them as
possible causes for other problems that we haven't found a solution for
yet. Thanks again. By the way the intermittent snow with hourglass
picture was just bad connections in the tuner.

Common fault on this unit is the MTS Audio module which
you replace and Tuner, you resolder.

Hi Ernie,
My audio is distorted too. I will try changing the sound module and get
back to you. Did your set have the intermittent snow with hourglass
shape? Thanks.

Kevin:
I had a problem with this model a couple of months ago.
The symptom was: won't switch to video , shows tv video on tv and video
functions. Audio also was distorted. I worked on the video problem for
several
days and was not getting anywhere. Should have replaced the SBX1637-11
module first. When I replace the MPS module it also cleared up the
video switching problem. The only explanation I have is that the audio
module must have been shorted and dragged down supply voltage possibly
also
used for video switching
