Hey Jamie,
sorry I cant help with your problem, I have no clue where to start.

But...
If it fails to be repairable, would you be willing to part with the PGMIV pretty cheap? Mine works excellent, but when I had that wreck in Japan that broke my collarbone, the front of the bike took a hit and cracked open the PGM case top. The PGM case is epoxied together and looks just a tad tacky. It would be nice if I could find a blown PGM unit so I can put the cover on my good PGM unit.

Since I had mine apart, I have just a tad info to offer. There is a switch that the keycard contacts when it is slipped into the key slot. Is that working properly? Are there error codes displayed? Is the display bad? I had to replace my display once already. The plastic top cover comes off from the lower aluminum PGM unit, but I dont remember how. I remember the black goo being extremely tough, so if you could find a solvent that loosens it up but does not hurt the board, that would be a huge help.

Good luck, hope you can find a good solution.

Hey, I also heard of a place in Tokyo called Kenso that supposedly has or had the ability to reprogram the NSR PGM's. I got that info from one of the Gaijinrider guys, and had a hard time believing it. You never know, though, maybe they can help you fix the PGM.
