Hi, I guess I have been fortunate not to encounter this type of problem on this chassis until now. I suspect the eeprom. I checked the menu setting and it shows "variable audio 1 speakers ON", "variable audio 2 speakers OFF, "fixed audio 3 speakers OFF". I tried to change these settings but no effect. The volume bar is functioning. I unplugged the set for several minutes to see if the Guide Plus would possibly be the problem but no help. I am getting error code 16 but I don't have any information as to what this correlates to. I checked all of my tips and old e-mails for help and all I found was to re-initialize the eeprom. I also tried an external speaker and tried the mechanical speaker switch in the rear of the set. Can I write the perimeters down before I change the eeprom like you do in the 177/187 series sets and place them into the new one?. As you probably figured out, I don't have Chipper Checker and I don't have it in my future. Any help or tips would be appreciated.
