Before checking the forums I saw that there was a new firware upgrade for the TSU 3000. I decided to downlad it and installed it. I had the same calibration issues as most people posting here. I then decicded to downgrade my firmware and now i get nothing on the remote. Going to email the Prontoo team and have them fix this dam thing! I hope that they going to fix this thing for no charge, they created this problem by releasing bugged firmware to to fix bugged firmware!
