Anonymous users2024-01-24Let's take a look at whether it's the line or the TV in the living room itself. (I work as an electrical repairer in my unit; You don't necessarily understand all the terms you say).
First of all: move the TV in the bedroom to the living room If everything is normal, it means that there is a problem with the TV in the living room, and the "high-frequency head" is generally broken; Or the TV is old and the cable signal does not match.
Secondly: If it is not normal to move the TV in the bedroom to the living room, it means that there is a problem with the wiring?
Workaround:
1. Replace a cable TV cable first to see if it's okay.
2. Open the wire box on the wall of the living room to check whether there is a short circuit, looseness, etc., and the wiring board has input and output interfaces to see if it is reversed.
3. If your line is "channeling", you have to check the upper interface.
4. When the distributor is connected in parallel, the output of the distributor "has one phase" is broken, and the interface is changed or a new distributor is replaced.
5. There are fewer times when the closed line is broken, so use a multimeter to measure the broken and re-thread.

It is repaired by the local cable network company, and you can call 114 to check their phone number. But there is one thing that needs to be reminded, your problem should be a problem with the home line, not a problem with the external signal, it is estimated that even if they come to check, they will not repair it, because the embedded line at home will not be repaired by them.
Find an electrician, there is also a set-top box that can only be used for one TV to receive cable TV, that TV can only receive 30-40 basic stations, if you want to watch cable in the bedroom, then you have to spend more than 100 to buy a set-top box.
Buy a 75 ohm cable coaxial cable, the length is the distance from the socket to the back of the TV. Measure it yourself, it's better to have a surplus.
Cable TV can probably go straight to the past, but the network cable can't. Either put a switch in the living room, and the bedroom network cable is led from this switch; Either use the four-wire connection method to connect the network cable, and divide the eight cores of the network cable into two strands and four cores, which are connected to the living room and bedroom.
If you have this hands-on ability, you can preliminarily check whether the line to the bedroom is short-circuited, broken or poorly contacted. If you still can't find the problem, you can only find radio and television maintenance. Because you must have a field strength meter to solve the problem to check the cable TV signal, you can only check the surface problem.
