My Primer2 was the newer version PC and developed the same problem as yours. This forum was of little help. My guess is they haven't found a real solution for the Primer2. We couldn't find the regular in the US in single lot quantites and didn't need 2,000 of them. Future Electronics, the distributor was kind enough to replace the Primer free of charge.

Hi,

Effectively your distributor where you bought your Primer2 can replace it. The ST local agency can also do it.
For European people, Raisonance can do the repair.
For guys that want repair by themself, Raisonance can provide some components.
