Hi guys.

Hoping someone here can help. I recently bought a CV that had the lighted apron from these guys: https://www.pinball-dreams.com/

The problem I am having is that it is emitting a buzzing sound when it is active.

Can anyone help as to why this may be?

It might be worth noting that I'm in Australia on 240v system?

I had someone around who advised that removing the earth will remove the sound, which it did, but then when lowering the playfield the sound came back due to the apron re-earthing to the game?!?!??? That and getting a slight shock when touching the apron is something I'd like to avoid...lol

It's such a cool apron, I'd really like to get this working so any help is really appreciated!

Ok, thanks for the reply!

Can it be stopped? It is very loud and noticeable during game play!

Thanks for the info.

I wouldn't say it a high pitched whine...more of a buzzing sound! I initially thought it was my speakers buzzing until I followed the sound!

It's definitely coming from the apron itself.

I'm a bit of a noob but when you say EL material this is the actual product that emits the light yeah? From under the apron?!? If so, that's what i happening with me.

Did you contact the guys from Pinball Dreams at all? I wonder if they have a possible idea.

Thank you mate! Will have a look tonight and see if this has occurred.

Underside looks fine. Only real lifting was where it enters the underside as shown. Pushed down, all good.

However, no I can't get it to light at all!!?? All I did was unplug it from the connection into the transformer/inverter.

Now I get no illumination??

Any thoughts?

Yeah, would appreciate the help please. Know nothing about these as it came with the pin.

Everything in the right way. Not sure what’s happened?? I have lighted flipper buttons on the same plug and they work?

As I bought the machine which was fitted with this apron, I didn't have installation instructions. Emailed them just so I could check it was wired right now that it has stopped working!

This was at the bottom of their detailed instructions:

"ATTENTION - Info regarding the noise coming from the aprons The used EL foil is electrically driven by a high frequency alternating current voltage of 1KHz and a currency of aprox 150v. Due to the size of the foil used to fit the apron this is also a contributing factor to the noise that is heard as the foil is in contact with the metal of the apron and this resonates the frequency of the electrical current within the EL foil. This is unavoidable and as before explained is a natural effect."

*sigh*

Yeah, nice idea, thanks! Something like this? https://www.jaycar.com.au/butyl-based-sound-deadening-material/p/AX3687

Gotta get it working again first...lol
