If pin 14 is always high the stereo decoder is forced to mono.

Do you get a stereo signal to hear at the headphones / speakers if you pull the connection of R104 (39k) and R65 (1k) to ground?

 

Pulled the R104(6.4v side) to ground, and nothing happens, the stereo signal is not doing anything. Measured 0v when pulling low on the pin 14 of IC4, so its pulled down fine..

I almost certainly have a spare tuner PCB but it will be next week before I can look it out

Well, the news is that I ordered a new LC7218 IC as I have seen problems with this before.

No change in behaviour what so ever !! So All caps and LC7218 changed..

Any bright ideas ?
