In Reply to: filter for cable tv posted by dave on September 07, 2000 at 05:25:26:
I'm just guessing but I would think it's related to your TV's power supply. When your TV is given a signal that has a lot of output in one color or at one time (many pixles on, all the same color) the power supply is bugging out on you. I doubt this has anything to do with dirty power supply or cable line, unless you get this noise all the time (I do and have to filter it out).I would take the TV to someone for a checkup and tell them what is going on. This assumes the TV is worth enough to warrant the cost of repair -- your call on that one.
If you are having noise all the time in addition to the text problem then check out using one of those $75 (or so) Monster power strips. They have a fair hookup for cable lines that elminates most (not all) of the ground-loop problems associated with Cable TV lines mixing and mingling with your HT setup.

Thanks for the response, but I get this interference on all my TVs, which include an XBR and my basic 35" Toshiba. Actually, it is less intrusive on a very basic 53" rear projection RCA. The Toshiba is plugged into a Monster 2000, and the RCA is plugged into a 1000. The noise only occurs during times when an extra layer of print, such as a phone number, is overlayed on the screen. I have seen this phenomenon for years, but this is louder than it used to be. I have cleaned all my connections. No change.
Does it occur when using DVD inputs or only cable/tv? It might be a funtion of the output of the cable TV ad itself -- an extra audio wave or noise.I remember hearing/seeing this phenomenon too but perhaps I've seen it too much or have too much background noise to really pay attention to it.
If it's broadcast-tv related I really don't know how you can filter it out unless you always hear it at a certain frequency. Even then you'd have to install a notch filter and deal with the sonic consequences of that.
As an aside, I don't think I've had cable for the last 7 or more years, so that might be why I didn't recognize what you mentioned until now. Maybe it's time to buy a DirecTV or DishTV?
The noise is only through the cable. No problems with DVD or tapes. I live in a heavily wooded area in northern Michigan, in an area with an association rule against cutting down any trees. I have had dish providers out to the house, and they have confirmed my fear. "As long as you live in this house, you will not be able to get a dish". Around here, dishes are aimed at a very low angle to Houston.
