X2 what Mike and Carol says. I got rid of all my older TV's back in 2009 and went to WALMART and got VIZIO Tv sets... 24-inch and 26-inch sizes for the RV's
Another item here.... Our local TV provider here finally made us all get small TV boxes for each of TV sets we are using which was fed by the cable TV signal and produced HDMI outputs. We used to feed every thing from one RG cable going through splitter boxes... With this new small TV box for each TV we select HDMI on the TV set to watch it. Both Audio and Video works over the HDMI signal...
So then I used one of those small boxes with my 24-inch Computer Monitor which had a HDMI input and the cable TV worked just fine with that. NO TV SET needed... each small TV BOX comes with it own TV THUMPER...
Maybe you can get something like this to work for you and just run a HDMI cable back to the Bedroom location... These small TV boxes are called Digital Terminal Adapters... When you first have these plugged in and connected to the cable TV they run a setup to find all of the available channels I guess... Then the thumper works... This is a complete digital TV tuner with a HDMI signal output... No TV SET needed - just a monitor that has HDMI input... Sometimes we have to reset them again (turn OFF and then turn back ON again)... If we need a new TV SET again I am just going to get a large regular Computer Monitor haha...
If your bedroom TV is older however it probably does not have HDMI input port as well haha... The VIZIO TV sets has multiple INPUT ports on the back of them. Mine has two HDMI ports...
