1978 280z Radio

[gotham22]

Hello everyone, I just bought a 1978 280z and love it!!!!  Its my first datsun!  I have what I believe to be the original radio.  The am works fine but the FM is just static.  Anyone seen this issue before?  Is it fixable?

 

Thanks

 Going for the obvious first. Have you tried lowering the antenna on FM?

[gotham22]

Yes, raised and lowered, no difference

Have you checked the antennae lead yet?

In case anyone else has this issue I wanted to provide some more info.  I sent the radio off to a repair shop who said the FM was shot and that it could not be fixed.  So I started looking for another radio.  The radio that came with the car was a Hitachi KMZ-2411z.  I could not find another one for less than $1k.  Looking through Ebay I found a Hitachi 2501BA for a datsun 810.  Turns out that although the model numbers are different this worked perfectly in my car.  Did not need to change a thing.  Also, it has a 5pin din connector at the back. I used this to plug in my iphone.  Works great!

Probably a cold solder joint somewhere on the circuit board and solder needs to be reflowed or a transistor is bad.

You can try taking the cover off the radio then poke and prod the circuit board while it's powered up to see if FM comes back.
