FM Transmitter trouble
 

Hello,
Lately the transmitter on my n900 has been cutting in and out.

I have found it works if I keep a little pressure on the lower right corner of the phone.

My solution for now has been to keep a piece of paper folded twice in between the screen and keyboard.

Before I take it apart and attempt a fix, I would like to ask for any advice on tightening the transmitter or placing a spacer to hold it down. Thanks
