I do not get TV channels, only a notice to please wait, channel will be available shortly. I have an old Motorola digital box, not a PVR. The power and remote lights used to show when watching tv. Now only the power light is on. The remote light turns on for a second, then disappears when turning the power off and on. Any idea on how to fix this? Or do I need a new PVR? Thanks for any help.
