Since you tried without success to substitute a "working" STB, it does not appear that the original STB is itself faulty. To verify, try moving the first suspect box to the location where the "working" STB was connected to determine if it operates correctly there.
If it does, then the problem is not with the device but with the location, and that means a cabling issue of some sort is causing the problem. Either (1) the cables themselves are faulty, or (2) the connections are faulty, or (3) the connectors themselves are faulty. None of these possibilities usually just "happen" in the normal course of events, so I must ask if you or someone else remembers making any changes in your home network wiring recently.
For example, did someone substitute for any of the cables involved, including the coax from the wall outlet, the cables connecting the STB to the display device, etc.? Was there a reason to unplug or disconnect any devices (for cleaning, for example) recently? If any changes have occurred, then there's a possibility that the equipment was not reassembled correctly. Check this out as a possibility.
If you can run through these tests and report back, we can go from there. However it it a good idea to make these checks and get data on the issue rather than merely speculating on what's happening. Good luck.
