Title: Cherry MX8000 G80-8200 PS2 ghosting. :(
Post by: dreamss on Tue, 31 May 2011, 12:29:22

I bought my baby used off ebay, black shell with brown switches and today i noticed that alt+shift+z causes ghosting on ESC. can dead diodes case this? is the matrix board dirty? is this fixable?

also my white shell with transparent switches has a faulty  x key, is this also fixable?
