HI @Lumm!
I’m just testing a solution using cyanocrylate glue to block the vibration from the display’s inductor.
I have tried to fullfill the space between the PCB and the coil using super-glue., like explained in this post:
Now it’s drying. If lucky, we would have a very easy solution for the issue.
Regards,
Excellent! Be patient and let it fully cure so as to have accurate results to report.
@jofemodo
I apologise for my impatience but does it work now with superglue under the coil? I am very curious… 
It kind of worked. The hum is now weaker, but it’s not totally removed. It’s difficult to measure, but i think you could try and see if you get better results, the same, etc. What is sure is you have to wait at less 2 days so the superglue curates 100%. I was impatient and tried before, this could affect the final result. I would like to repeat and see if o can reach better results.
Perhaps a different superglue brand could work better. I tested with a generic brancd, but I would like to test with Loctite 411. Etc.
Regards,
Thanks for reporting.
Can you please give an exactly instruction where to put the superglue? I have no idea, sorry 
hot glue on top of the superglue?
I am not native english speaker and often don’t catch if it is a joke or serious. But I like to say that hot glue would not work in this case.
‘Is it a joke?’ Is an extra level of jeopardy we add onto the language to trip up people who mistakenly think English is easy. Wyleu is an advanced practitioner.
That and the 9 pronunciations of ‘ough’, and the 64 definitions of ‘set’.
As soon as you can order the display as a spare part in the shop, I would give it a try and seal the coils with glue to see if the chirping goes away. I could imagine that 2-component epoxy resin glue would work well. I remember that from my model-making days. If someone could post a photo of the display coils that need to be sealed, that would be great.
It was a fairly serious suggestion as ultimately sound suppression is about absorbing energy. The epoxy may well limit actual component movement but the hot glue ‘might’ and it’s purely a might, absorb some of the sound energy within the area and help reduce the noise, or at least some of the particular harsh overtones, which may be adding to the sound.
As baggy says English humour is a difficult concept at the best of times and the English language, as I understand it, is one of hardest to understand simply because it has no real rules, a preponderance of nouns and much historical bagage picked up along the way. This explains a certain element of my approach. It’s requires me to read people’s reactions and issues carefully enough to try and produce something rather more than RTFM. It is truly wonderful when people do contribute something as it really makes the whole experience worthwhile, and demonstrates how much wider the combined imagination is than our own individual predictions. What people might do with this tech that we, as a group, have nurtured over the years can be incredible
Sorry for a little baring of the soul. I’ve run software teams for all scales of organisation among other things and I believe I have a slight understanding of quite how to make this sort of thing engaging. As it says if it works for you great, if it doesn’t just ignore. I won’t be offended.
The theory of this fix is that the glue is sufficiently fluid that it wicks under and into the coil. This won’t happen with a thick viscose glue like epoxy. Even some cyanoacrylate glues are too thick.
If someone (@jofemodo) posts a picture of the offending part, I may try this solution.
2^8 wouhahou
I know, let’s say …, maybe, 2^2 of them:
A badger set: a place where a badger lives.
AS Mr Adams said, it really is rather complicated.
for example…
I took the shell off my champion racing snail, thinking it would make it faster. If anything, it just made it more sluggish.
A set of pictures with the part to put the glue in would be very much appreciated. Thanks.
Remember to let the glue set hard
“I’m so upseted to be in such an ignorant set”
Is that correct ?
@Lumm question is more accurate btw
If it works and your happy with the zynth, put a band together for a quick set.
Ready set, go…
I feel like we should let the sun set on this conversation.
Yes, but you are very set in your ways.
