| What could cause this problem?
I have the following recurring problem, and am looking for insight on what might be wrong.
I have 2 separate cable lines coming into my home. This was to fix problems with signal loss due to the crappy loop wiring scheme put in by the builders. Line 2 comes into a 2 way splitter, each output of the splitter goes into another 2 way splitter, for a load of 4 TVs total. One of the 4 has a digital cable box, the other 3 lines just go to TVs. I have been seeing problems on the side without the digital box. I'll notice a signal degradation on the 2 TVs on this side, it is very noticeable on the low channels, hardly at all on the high channels. If I disconnect the TV that seems to have the worst picture of the 2 from the splitter and reconnect, the problem goes away. Sometimes it takes more than 1 reconnect to restore the reception. Reception is then fine for varying periods of time, sometimes hours, sometimes days. The other 2 TVs connected to this input line on the other side of the 1st splitter do not have any problems.
I tried replacing the splitter with 1 I found in a box of cables, etc. I had lying around. The problem still exists, though it seems a little less frequent.
The TV with the most problems is in the kitchen. We have a tin backsplash built around the entire kitchen counter several months ago, could that somehow be related? The backsplash was in place for quite a few months before we started seeing any problems. | |

| If it's more noticeable on the lower channels, it sounds like you have a loose connector somewhere. If the buiders screwed up the wiring, chances are, they didn't properly prep the lines behind the wall plate. If you can, pop the wall plates that you are having problems on and see what kind of connection you see. If they are poorly crimped, loose, or the push-on type ends, they should be replaced. Best connectors to use are compression fittings, but they are a little more expensive and you need a special tool to terminate them.
If you don't feel comfortable doing this yourself, my suggestion would be to call your provider and have them change all ends behind the wall. (they probably should have done this to begin with when they hooked you up) If you have some sort of wire protection service on your account, they shouldn't charge you anything for it.
The backsplash you were referring to shouldn't have anything to do with the problem, unless they accidentally put a nail or staple through the cable when they were building around the cable outlet. | |

prob sounds like ingress, could lie in the f connector or the braided shield all it takes is one strand to mess up the picture. | |
