Quinte Fishing

I have a vexilar fl-22hd and it makes a rattling sound. It's not the normal vexilar hum. It's not coming from vibrations through the unit because it still has a rattle sound when I take it off the unit and just hold it. The rattle some what goes away when the vexilar is perfectly facing forward but gets very bad when I tilt the screen up.
The unit is about 7 years old.
Does anyone know what could cause this rattle? I have disassembled the entire thing and can't find anything that is lose.
Any thoughts?

That is signs of a big fish........
Actually if it is anything like my FL12 it is okay. My 12 started that noise 3-4 yrs. ago and it has not hurt the unit at all, my 12 will run for hours or days and will not make the sound you are talking about then it may show up from time to time. I believe the cure for it is the internal brushes brushes can be replaced but as stated not a needed repair until either end of season or wait for it to crap out.
