Boss Tuner only works with battery, but.....

I have two TU1s that I've been using with aftermarket nine volt power supplys. They both work fine with all my guitars, but suddenly, when I plug in my Gibson J45, the signal doesn't seem to trigger the correct response with both the tuners. The tuners appears to acknowledge that it's getting a signal, but just shows random flashing LEDs. I changed the battery in the guitar, and nothing changed. Finally, I tried using just a nine volt battery in the tuner, and it works normally. This only occurs with that one guitar. Has anyone had this happen? Do I need to buy the Boss brand power supply?
