I've got a Coby TFTV4028 (40" LCD) which has a couple of problems, the most irritating of which is the fact that the Toslink audio output (the only option offered) is apparently not working correctly.  I do get a visible red light in the Toslink cable, which I process through a Toslink-to-RCA processor in order to use an older HT receiver in my bedroom.  I am not familiar with the light-fiber-audio circuitry.

 Audio circuitry works -- the built-in speakers work fine, and the volume control works well, also.
 
 I have tried two different Toslink-to-RCA adapters, one of which is brand-new, and neither provides an analog audio signal to the receiver.  An MP3 player into the TV inputs works fine.  Toslink-to-RCA adapter into any other input provides no audio.  Hence my determination that the audio modulation for the Toslink out is defective.
