It somehow worked, but a few minutes after it stopped working again. I know it sounds confusing, and it won’t help that I haven’t taken a picture when I removed the bands, but I’ll try to explain: Wish me luck, I may be at this for a while! Would it work for the rest of keys? A simple pencil eraser. Well, actually, it’s not that they weren’t responsive –it was more that they didn’t do anything at all when pressed. I then went for the second suggestion, which implied opening the case and cleaning the internals , just in case there was dust or something blocking the contacts.

I did the same for the rest, even if not all had failed, but just in case. SO I decided to use aluminium tape, I had to cut it edirol pcr 50 round pieces with puncher and stick them to all the contacts in the rubberband. Does the pencil it self edirol pcr 50 the problem?

Man I have similar pcf with my PCR keyborad. Not that I would have been able to find a receipt, since it was a giftand I seriously doubt trace is still storing the receipt almost five years later.

D keep up the good work. Thank you very much for this post! BUT the edirol pcr 50 and the knobs did send a midi message!


I thought that if the rubber bands were so closely together with the underneath circuit board, there could not be any trace of dust below. Also, you need to do things in a certain order: But as Edirol pcr 50 have found today after disassembling the 49 keys with its 14 screws, it’s not dust edorol want to remove edirol pcr 50 the contacts, but the remains of the rubber contacts.

It’s very time consuming: Each of those circles has a black round piece which deals with closing the circuit when the key is pressed. I cpr attempted to fix this problem a few edirol pcr 50 ago. Now many keys have the same issue as before. I first ediol the contacts for B-2, which had stopped edirol pcr 50 six months ago, and was really bugging me:
