[Solved] Sony PS-F9 turntable. Disconnected component don't know where it goes?

I am not an electronic expert in any way. I usually just repair, or try hard to repair what I have because absolutely no one is technically qualified where I live, Sadly..

Sony PS=F( turntable, the Japanese Version, which I can't seem to find a service manual for. The one I could find everywhere is the manual for the Canadian version.

The difference is that the jap version has an FM transmitter which was working great until I decided to replace the back-cover screws because their philips head seems a bit corroded. Anyway, I replaced them, but being dumb enough, I forgot which one goes where and there are difference sizes lengths for the screws so I just lifted the backcover to check where the tall ones and short ones go and put it back..

While doing so, I probably knocked out a leg of a component that was soldered to the board. That component, after searching looked like this
(googling, it seem like a choke)

The turntable still works, but no longer FM transmits.
Is that loose leg, probably, the reason why the FM thing stopped working?
Here are the actual photos from inside the device

I can't seem to find a place on the board that shows a sign of a disconnected component.

Service manual of the canadian version <<<<

So the FM transmitter only works with a DC power supply, when using battery it does not work. That is how it is designed not a flaw. Now it doesn't work on either. Normally, it starts transmitting once the device is connected to a power supply and even if the device is turned off (on/off button is set to off) it still transmits an empty silent transmission.

I would appreciate if someone can help me of where to solder the loose leg and I am ready to open the back cover any time to give you more photos or any info you need. I just fear to go under the board. Highly sensitive wire connections that give me a huge fear..
 
The transmitter is underneath the main board and shield by copper foil as you can see. You should find out the power wires connecting to it. the component is an inductor, used as a filter some where in series to positive or negative supply of the transmitter from main board. check near DC socket.

Thank you. I managed to re-attach it and going to mark it as solved.
Unfortunately, The FM part no longer works.. must have shorted out somewhere. I am so afraid to take it apart. Definitely one of the most delicate devices I have ever seen!! I am in the process of searching for the Japan model Service manual but can't sadly..

Hopefully I will soon.

Thank you for taking the time to read my post and explain how it works and where it should go.
