Just upgraded my TV and internet packages. There seem to be a few issues, most annoying among them being the random interruption of a program's screen display with an endless slide show of mostly tropical images.  The program's audio feed still continues in the background.  The only way to snap back to a program's display is to click the remote's enter key.  This same problem takes place on all of our three TVs and on any channel.  There's no point in playing back the last minutes of program time in the hope of retrieving sound with picture, either.  The rogue images are still there.  How do I fix this aggravation?
