Sound won't come on with the tuner

First, try unplugging all of the sound system and plugging the amplifier into an outlet on a circuit that was not changed by the electrical work. Also, plug an outlet tester into the outlet you were using for the amplifier to make sure it is correctly wired. If one outlet in a system has hot and neutral reversed and others don't, this could cause problems with some designs.

If you are lucky, dirty power from sparking inside the circuit breaker crashed the control circuitry in the amp, and it just needs a hard reset (power disconnect/reconnect) to be made functional again. In the worst case, something got fried and you'll have to use instruments to track it down.

Are you sure the red and white wires plugged into the audio output on your TV because I had the same problem and learned thats where you plug them into

It sounds that the tuner is faulty. Befror confirm it, a through checkup is necessary. Seek tech support.

I have the same problem with the same model, the radio stations cannot be heard, I am in Mexico, they tell me that it is the radio tuner that does not work

If the main amp section does not have it's own fuses, then the fuse might have blown, because the amp has gone. However I think it is highly likely that you have taken out the main amp, especially if it is a single IC that does all the work. You should try and determine if the amp section is getting power before replacing it.

Your output I.C. might be faulty. Output I.C. is the one converting the audio from cd's,tuner,auxiliary to sound which passes to your speakers.
Since your Output I.C. is defective then the unit will not generate any sound even your inputs(cd,tuner,auxiliary) is working.

It is quite technical so I've advice you to look for a qualified technician to isolate the problem and do resoldering also for some dry joints on the main board.Dry joints also will might caused for damaged a parts.

Thanks for using fixya.

sounds like you probably blew the output ic.

unplugg your tuner from the AC wall outlet then check the setting on the tuner do not try to watch and listen to the tv only try to listen to the radio or a CD and select the right option on the tuner to do so. If you have sound on any of the functions....radio or CD/MP3 then the problem lies on the setting not correct for the TV/VCR/DVD mode.

I asked Nuvo about this and they said that the RS232 port was never setup for control, it is only to be used for programming when they are initially setup by Nuvo.

I have codes for the Essentia and Grand Concerto that I have written but non for the simplease as Nuvo said it cannot be controlled.

Cheers,

I have the same problem. All keypads blinking in All Off. I changed the fuses on the Nuvo. No luck. Does anyone have a solution to this?
