Cannot figure my coax cabling problem. I just installed a second tv in my bedroom and when I connect my coax to the splitter to go to the new tv my #1 tv goes blank and says no signal. I've tried different splitters same problem. I've got an amp installed before the splitter I've tried it before and after the splitter. Tv #1 works great until I hook up the coax going to tv #2. That's when it goes to no signal and goes blank. It's driving me nuts trying to resolve this issue. I know it's got to be something simple I'm overlooking.
