FiOS was installed 5 days ago. The TV interface is via the Motorola DCT700 Digital Adapters. We just noticed that the channel number is not always displayed when you press the Up/Down channel button or the FiOS TV button. Earlier this afternoon, it was being displayed. I then powered both the DCT700 and the TV off with the one button on the remote. Now I turned both on and the channel number would not appear when I changed channels. I unplugged the DCT700 for about 30 seconds, plugged it back in and that solved the problem.
