Resolved STX16803 : working but noisy (I mean audible noise :))

Dear DL Team,

I recently bought a second-hand STX16803 with FW-7. The camera works well in terms of image acquisition and download.
There is one thing that worries me a bit: I can hear a quite "strong" noise coming from the heart of the camera. I upload with this message a very short video where this noise can be heard (with fan off). I have used other STX16803 in the past and I don't recall there was that noise.

Is this noise characteristic of something in particular or it can be anything?

Best regards,

Simon

 

Hello Colin,

STX serial is X17120008
FW7 serial is FWX171213

It was on (I'm using Prism and there is no obvious way to shut down the cooling, I should try another software)

Yes that is the original power supply and it is directly plugged in the camera (using the 4-pin to 6-pin adapting cable)

Yes the FW7, but I disconnected the I2C connection cable for the test.

Hope this helps,

Thanks a lot for your kind help,

Simon

 

Ah ok this would explain then why the hum "stops" when taking a picture, and starts again when the exposure is over?

Yes I have the 4.05 nothing to update on that side.

I'll check the difference between MaximDL Pro and the current software I use.

Sure I will

Thanks again and greetings from Switzerland,

Simon

 

Just did, there was indeed one file that had to be updated. It turned out that the hum is indeed modified: it got higher in frequency. Is that expected?

 

Yes that was 2.53, now 2.54.

And indeed higher-pitched hum in 2.54 compared to 2.53. As soon as this is not a sign that there is a potentiel problem (as you said already), then it is all fine

 

Exactly, I just tried
