I do not have any more sound on the optical digital, and on the coaxial only get really low noise. I tried to Replace capacitors C927, C928, and C929. Didn't change nothing. And then i found out i only have to cut C928 without replacing it. Still no change.

What can i do now ? Please Help Thanks

Problem with the series were known to be caused by shorted electrolyitc (low voltage) on the signal pcb. Mainly being the C928. It would however cause a "no audio" only due to pulling down one of the VCC lines. ---not low noise.

Any of the low voltage electrolytics (10v & below) could technically cause problem (Can check all of them in ckt for a short b4 pulling). If c928 was in fact shorted, more likely problem is either a regulator or possibly "man made" after the fact.? can you measure any DC where C928 is/was?

But based on your description, not sure if it is a cap issue. May be a signal process or perhaps a connection issue, both of which are definately not worth
the cost/time involved on an entry model.
