Hi everybody, I have a sound problem on my JP Premium. There is a high pitched 8bit sound in the background while the music is playing. I have already done some tests and it does not come from the speakers (the sound come from the speakers, but the speakers are ok), I also tried with another sd card and
it's the same. I checked the connections etc ... but I think it comes from the source. I have no experience with Spike issues, is this a known issue? Has anyone ever had this problem here? The code is 1.03 and system updated 2.60.
I posted a video on Youtube to show the problem. We can hear the parasitic sound at 0:05.
Thank you in advance.

I'm sorry, I misspoke. This parasitic sound comes from the speakers, it is played by the three speakers. It does come from the speakers, what I meant is that the speakers for me have no problem, vibration, damage or whatever. In the video I went to the Diag / Speakers / Main theme menu. You can hear this sound during play at times, but not all of the time. On the other hand it is always audible at the same time of music. In the video it's more audible at 0:05, when i play it's the same sound at the same time.

No. That whine sound is only listenable/audible when music is playing, but always at the same time of music (like in the video, at 0:05 it's more loud). When there's no sound at attract mode for example, this whine sound doesn't exist.
It seems to me that the amp have a little issue.

Thanks, the music attenuation is now at 0, it was before at -10 but it doesn't change anything. I already check the impedance, both speakers, backbox and cabinet, at 8ohm.

Stock 1.03 firmware, i don't know what is the AV edit 40TS, you mean the custom version with original soundtrack of the movie?

Hi guys, i've got a sound issue with my JP Premium, i made two videos to show what is going on.
I already tried a new CPU board, 3 sd cards, speakers, Power board, settings 4ohm/8ohm, attenuation etc... For now i found nothing.
It seems that problem is only present with JP Premium owners (very strange because Premium/LE share the same code...)

So, i would like to know if some Premium owners can see the videos and do the same thing, and tell me if this is normal or not.
In the first video, the alliasing parasitic 8bit sound can be heard after 20 seconds. In the second video, it's the sound #183 (Diag/Speakers menu) and it's louder.

Thanks in advance

It's not a vibration but maybe a distortion from the amp when certains sounds/frequencies are played.
You can't hear the problem? does the videos works or you can't hear noise? it's very clear on the first video (Main theme from 20 seconds)

I already changed the cabinet speaker, and tested each speakers individually. But this weird sound can be heard through the 3 speakers.

About your first question:
Yes I opened the code with Pinball Browser and don't notice the noise during the Main Theme trough my PC speakers, and i listen it at a loud volume.

Second question:
I already did that, i checked each speaker individually, the noise is present in each speakers, i even changed the cabinet speaker.

I saw you have a Premium too, can you listen the Main Theme in the Test menu (Diag-Speakers-Main Theme number 1) and tell me if you hear something like my video?

Thanks !

It's not a physical issue, the noise comes from the speakers.

For information, Stern engineering is looking at it now (i contacted Technical Support).

I readed it too quickly, sorry.

Anyone changed the stock warm white leds for cool white? I really don't like the warm white leds...
