Leader 3216 AM/FM Signal Generator_AM/FM no output signal

[anupong1983]

Hello All,

I'm hoping someone out there can give me a bit of insight into this.

I tried to repair RF board of Leader 3216. the 3216 no AM/FM output signal (RF level is fine) measured by measuring receiver.
I don't know which parts are AM/FM block on RF board because I don't have circuit diagram.
 
kindly advise if you know which parts are AM/FM block and also advise which component is defective.

Hope anyone can help to find out this case, I will so appreciate.


Thank you so much.
Anupong
