Hi all,
    I have an RCA CTC177BH2 with no sound, not even a click or hiss when 
the TV is turned on.  Video is good from both the tuner and video-in (no 
sound out with audio-in from VCR either.  I had the TV to fix a cold 
solder joint under the RF shield.  While I had the soldering iron in my 
hand I also reflowed a number of joints on the LA7610 (signal processor) 
and LA7765 (stereo processor), I didn't touch the TDA7263(Audio AMP).  I 
don't know if the sound was working before hand.  However the I have 
confirmed that the speakers do work.   Any thought on where I should 
look first?


Does anyone have a data sheet for the LA7610?

Thanks, Sam
