hi

You should buy new inside keypad foil,  or clean inside keypad foil contacts at the end.

As above the buttons that have fail;ed indicate a fault on the 'C4' group. 

If you're happy to take it apart there's a small metal clip that connects the foil to the PCB - this can sometimes come misaligned and cause the above fault, but it's possibly a broken track on the foil itself.

I've replaced several and it's quite straightforward - you can see the part number in this photo:

(EDIT:  I usually buy them from here: link)

And here's a useful thread about taking Beo4s apart - it's written for screen replacement but the dome foil replacement will be just as straightforward.

Thanks for all the replies!

I took apart the remote today and first thought that the bottom part of the PCB had snapped off completely ... before realizing that is by design 😳

Anyway, not exactly sure what the "small metal clip" Guy is referring to, but i suspect it's this part?

Not exactly sure where to go from here though ... i guess it wouldn't hurt to clean the contacts with some isopropyl?

Yes that's the clip - quite easy to slide off (downwards) and replace.

Before you do so, have a good look at the traces on the plastic dome foil - there may be an obvious visible break in which case it needs replacement.

Otherwise, try unclipping the dome foil from the PCB and then clean gently - I think isopropyl will be fine.  Then replace, making sure that the contacts on the dome foil line up with those on the PCB - the holes assist with this but there is still room for error.  The metal clip is just there to apply pressure, rather than provide electrical contact.

I have had success in the past by removing and reassembling a few times, but if you have no luck then I would replace the dome foil.

Does it cost a lot to get the foil replacement?

Last time I purchased new foils they were £14.98 each from here: 

Thanks Guy
