Found a brown wire and a red wire from speaker cut from board. reconnected and still nothing.

The E-prom will kill the sound on these. Dont remember
any other audio problems.

Does the rest of the set seem to work well?
If so, maybe the on-board tuner issue has been repaired. If the E-prom has been corrupted, they used to supply replacement chips, programed with average settings. Probably NLA.
You might have to get into the service menu and check the audio settings.

I don't remember the access code. You might need a genuine RCA remote.
Maybe Zeno or another tech can guide you.
