Both times this problem occurred on my VIP222. Although the sound of the channel would be normal, and the guide would display, there would be no picture on the TV. The first time this happened it was on the TV2 output. The second time was on TV1. When I changed the channel the banner of the new channel would display and the sound would be there, but still no picture. Both times I had to hold down the power button until the system reset, and after everything rebooted (which can take as long as 15 minutes) the picture would display normally. Any thoughts?
