2000 tahoe radio works but no sound, radio powers up, station tuning works, but no sound, radio fuse checked OK

Did you actually check the radio plug for power, or does the display just not illuminate? I ask because this radio has a little bulb inside that burns out that illuminates the clock, and radio station. You can confirm this by trying to use the radio normally, and trying to 'seek' a station. If you can get it to tune in, it is definitely the bulb. Another way is to shine a nice bright flashlight into the clock face. You should be able to see the stations and clock, that at least will tell you that the radio is working. - Hope this helps =)

Was it just replaced? No tuning is the antenna wire wasn't plugged in. It would get stations manually, but with static. Not lock by itself. No sound could be a bad replacement radio or an amp. Check the amp fuse first.

u need to check your antenna

all cars now have radio codes.
when lost some go dead, 100% others tune ok but sound is cut only.
in your case. check fuse first
some cars have seperate amp. and its own fuse.
this is all covered in the FSM and at alldata.com. USA>

so the radio dont tune, most you can see it tune with the seek button
see it scan and stop at station, this shows you it has power.

check for blown fuse the amp may not be powering up

that sounds strange. you maybe failing to check one fuse. check all locations for fuses in your car. normally under the hood, and under the dash.
it can also be a relay not working, try to follow the cables from the fuse box once you identify which ones are the ones that control those accesories.

if you dont get even a pop or crack when turned on at first, check the radios memory on the read-out on the radio face and see if its on mute setting, and if this is not the case, there are 2 fuses,one controls memory power and the other controls audio output power, check both as if one fuse is out the other cant make the radio operate properly

2008 Altima radio-the sound just quit working. Everything else seems to be OK. I can change the radio stations, but no sound. Is there a fuse that could be bad?

because of security features in newer cars. your probrably better off taking it to the dealer so they can reset the codes.

hi,seem your radio is ok,better to ask your dealer to your radio,or bring your unit to authorize radio repair,ty
