Key contact strip repair.

2012-11-13 by Nicolas

Hi everybody,

I know this is not about a vintage synth but it could be useful.

I'm trying to fix a old Roland HP-5000SL digital piano that a velocity problem on one note even after the rubber key contacts have been replaced and the contact strips have been cleaned. 
I think the contact strip (board) is worn.
Those boards aren't available from Roland anymore.

Is there any way to refurbish the carbon contacts on those boards?

Thank you!

Nicolas

I use graphit spray from Contact Chemie.

Best regards.

This may be a terrible bodge, but I've found that drawing on them with a soft pencil seems to do the trick in my Nord Lead 2. It's worth a go. Still seems fine 12 months later.

Best Whooshes,

Well, it's definitely a synthesiser, just a highly-specialised one that pours all it's power into making piano waveforms.
Try the soft pencil thing. It also worked on my mate's Motif, which had velocity-sensitivity issues.. and that's used a LOT, still ok after 6 months, easily reapplied. It's possible to overclean those contacts too.

This is a great moderately priced product I used to rebuild a dx-27 contacts.

Do not rush the instructions as it needs the time for curing. Basically you clean, crazy glue and coat with conductive liquid.

I think I paid $15 and used ¼ to do a keyboard completely. Its still working.
