Hello! Another case Subject S7-312 1. All LED's are blinking 2. No MPI connection 3. Factory reset finished, except the last state. It did not go to stop after delivery state without buffering. It just began to blink again. All other steps finished fine. We tried to connect during different states with no result Can it be deffective? Will it go to stop mode without memory card? (we did not try to put it again yet) ------------------------------------------------------------------------------------------ |
