FS7: FX9 jingling noise

[david dominguez]

hey guys,

I just bought a second-hand FX9 and I noticed a jingling noise when bumped or when attaching a battery etc.. Anyone know if this is common, or if their FX9 makes a similar sound? So far there aren't any issues.

Here's a video of the sound https://www.youtube.com/watch?v=Eeb5XO0aMB8&ab_channel=DavidDominguez

I reached out to Sony but haven't heard back yet.

Thanks for your help!

After watching it 10x, I still think it's something that's rattling on your table because it's such an unorthodox sound to be coming from inside of the camera, even if something is broken.

Maybe a loose heat sink but have no idea.

It's not coming for the table. it's definitely from the camera

Is that a table? Looks like floorboards? If so that's a fairly hard unyielding surface. Could be just vibration resonance from the heatsink louvers in the camera as the vibration of the thumps are conveyed into the camera body. Can you get it to make that sound when it has been turned on and got fully up to temperature? Maybe it might not do it then as the heatsink will be warm and have expanded and be less likely to resonate. From exploded images I've seen of the FX9 it looks to have a similar two copper pipe to heatsink fins of the FS7. When you run your fingers over the fins in an FS7, been in there a couple of times, they make a 'tinny' sound when they vibrate under your fingers.

Hi Chris,

you're correct that's the floorboard. Yes, it still makes the noise when it is powered on

Just for the heck of it, have you checked the top plate & handle and shoulder mount?
