I have a good picture but no sound. Any ideas? The model number is SR3273DT and I have a schematic.

Thanks

: does this set have two modules if so check the audio output ic810and resistor rx1499, also check the caps around the ic.

No. However, I have narrowed the problem to ic1400 (221-683) using an oscope. I had an input but no output. I found the ic on ebay for $5.35. I will keep you posted on the outcome.

Thanks for your support.
