Thank you for your prompt answer, I will send the unit for repair. I checked in the previous discussions and forums, and the same case of channel A freezing appeared on some occasions. Is this a hardware problem that need to be fixed? It would reassuring to know what exactly is causing this. My unit is only 2 months old...
Thank you Michael. I had bought the unit from Interworld and they made a swap with a new one. My unit has the S/N IAT0/033. When the unit gets back to you, would you please keep me informed on what went wrong, either through this forum/topic or to my email?
