Heya as new in the Stern -modern games there are a few things that confuses me with my newly bought RBION.
In the backbox these metal 'things' are clamped on the flat cables that goes to the DMD. Are these stock or after marked add-ons? What are they supposed to do? What would happen if i remove them?

Also: One vertical line is out in the DMD, is that an issue for the rest of the DMD or the cards, or could i wait replacing the DMD (as the vertical line is not that disturbing in game-play) with out any risk of further damage to the pin?

And: There are a pretty loud hum from the flipper coils when held up. Louder from the right than from the left (perhaps because of there are two flippers activated with the right button?). Is this normal with newer Sterns? Could I address it some how, the sound is pretty annoying.

Thanks, so these are supposed to 'remove' high frequency hiss then? Is that a frequent issue on RBION (or modern STERNs?). Aftermarket Add-on or original from STERN-factory?

Thanks, I was hoping on something like that. The missing line does not bother me that much so I will just leave it be. Thanks for the offer tough.

I second that!

Flipper-hold-hum, anyone?
Standard on modern STERN pins?
