Tuner SH-2294VO (inside Denon DRA-295 AMP)

[lexios]

Hello all,

my DENON amp, is not tuning right (from the date it was bought). This is what it does:

1. I tune in to a station. The freq. is right and locks.
2. It tunes in Stereo
3. Then, as I am listening to the music, when there is bass music or voice, the Stereo indicator blinks to the rhythm of the bass. Also, the RDS inidcator is blinking to the same rhythm. The audio is very annoying, going stereo-mono to this rhythm! I have tried with stations all the way from 87,5MHz to 108MHz. The problem remains...

The tuner, a Shen Zhen SH-2294VO is very complicated for me. It has lots of trimmers and I don't know which to try to fix this weird problem.

I am uploading 2 pictures of it... If you can point me to the right knob/trimmer, I would be grateful!

I found the right one! I am posting a picture for others to see...
This is from the official Service Manual that I found. If you have a Signal Generator for 90Mhz and an oscilloscope you can make it perfect. Otherwise, make it like I did, by listening to it.
