We set up a OTA outdoor antenna. Connected the existing two coaxial cables to a 2-way splitter. When we tested our old TV (not smart) it worked fine. When we tested our new smart TV it worked fine. But when we checked the old TV it wasn't picking up any signals. After a bunch of tests, what we found was that the old TV would work only if the smart TV was not on on. Could the smart TV be sending a signal that disables the old TV? Could the smart TV be pulling too much of the signal? We have an antenna booster on the old TV but the not the smart TV. Any ideas?
