F12e missing led's

So poking around the circuit board i noticed there are three spots for led's
two of them have no led installed
The installed led is for the power indicator

The other two are on either side of the power indicator

I traced one to whats labeled AV_LED. So can i just install the led and have an AV status light?

I would need to remove the board to trace the other. Does anybody know where it goes and its function and also can i install a led in this location?

Thank you

Yes, you can add an AV status light,You turn on the 5.8G image, the LED in the red position will light up.

Thats excellent information. Thank you. I will soon have an AV status light then and while im there i will try to trace the other led and see if it has a function we can use thank you again 52dgj
