I disconnected my Negative battery terminal when changing a knock sensor & O2 sensor, now my radio comes on but there is no sound despite being on a known local station. No sound from AM either, but digital tuner works. Basic Nissan tape deck AM/FM stereo? Any Ideals? I disconnected both terminals for an hour then reconnected w/o any luck? Antena goes up & down with turning radio off & on, checked for blown fuses but all look good.

Appreciate any imput,
Thanks

This may sound like a smart a.s.s suggestion, but have you tried adjusting the volume?

Yes, of course, but no sound from speakers at all

Check your fuse. I had that problem before with a HU i installed.. and it burned out a fuse in my fuse panel.. I sent the HU in took me 6 months to figure it out. lmao letme no how i turns out..

fuses okay too, replaced just in case & no improvement

Radio, shot, ended up replacing w/ pioneer system

Sorry for that sarcastic reply earlier, but here's another one for good measure. Kinda a long diagnosis process eh? j/k

is the set coded, as in having to enter a security code. i come across this quite regular here in the uk. the set works but no audio.
