THERE IS NO audio frm my fisher tad-9925.....the ic has just been replaced but still no audio.....cd is playing but cant hear anything
Its a little hard to diagnose over the computer.
I assume there is no sound from the amp EVER.
I assume you have tried other sources.
I assume the unit worked OK until the IC blew.
I assume you replaced the IC yourself?
Often, parts with the IC also fail. There maybe fuses that look just like little resistors along with the IC. They might be blown.
There are parts in the circuit to test if there are speaker problems called power resistors. These will frequently open circuit when the IC Blows - you won't be able to see anything visually.
If your stereo normally makes a 'Click' sound just before the sound comes on, and now there is no click, this indicates the repair of the IC is not complete yet - find the blown part.
