Yesterday, this Hathway guy came to install his STB as a demo for two days. We live in an apartment, where input TV cable comes in and connects to three other places within the apartment. We've a 29" TV in one room, and a computer with a TVtuner card in another room.He connected the STB to the 29" TV, and everything worked perfectly. After he left, I took the STB and connected it to my TVTuner card. There was a problem. Some channels like MTV, VH1 Zoom etc weren't able to catch proper signal, and "No Signal" appeared often. Wierd part : When I switch on the big 29" TV, I am able to receive those channels which had "No Signal". As soon as I switch the 29" off, its back to "No Signal". Its weird !!:wall:Help me. If there is a solution then I might keep the STB, or else I'll give it back.
