    Just wanted to update this thread with what I did to solve the problem. A few weeks ago, I went ahead and followed the suggestion above to buy an isolation transformer. Kinda pricey solution for one problem device, but really had no other choice (albeit probably a good thing for this $3K tv, since the power here sucks). Got the Tripp Lite IS500 (500 watt). Plugged it up on the filtered side of an existing Filterlinc. Turned the TV on and let it get all warmed up throwing all kinds of noise out and wholla... I had full communication again! Turned lights on the problem circuit on and off many times with out missing a beat. Before, when that TV was on, a number of lights on that circuit would get a signal maybe ~40% of the time.

    But, just for good measure (and since I still had the rare occasional module not respond, but it was this way before the TV), I went ahead and ordered a TI103 from Homeseer. Been using it for a couple of weeks now and I don't think I've had a single module miss a command. I was somewhat reluctant to invest more in X10 stuff, but I just don't have the budget right now to start migrating to newer tech and X10 still works wonderfully for me. I must say that I was impressed with the build quality of the TI103 and the documentation is probably one of the best I've seen for a simple device with a simple purpose. I know that sounds stupid, but when I purchase a product, a lot of times my gut feeling on quality is based on the time put into the documentation, I don't know.

    Anywho... both of those are great suggestions for anyone poor like me still hanging onto X10 and having little problems.

That product he mentioned is desribed directly as a "noise" filter, which may mean it is designed differently that the smarthome line of filterlincs. If I recall, smarthome usually markets filterlincs for use more to keep x-10 from going into devices that would absorb them. Noise filtering seems to be a second priority.
    You would have to put it in a box of some kind. It would be against code to just have it hanging in the wall. Either a multigang remodel box or a flush mount junction box would work nicely

    LCD's have switching power supplies which are a big "absorber" of X10 signals, so it could be that your LCD is just sucking all the signal when on

    I've thought about that, but according to my (very simple) amp calculations, I'm only hitting around 8.5 amps (at full load). Even then, that wouldn't explain away using another filter on just the tv behind the other existing filter. That one 10-amp filter for just the tv couldn't have been near the limit, as the tv pulls ~3.4 amps max. I really think that these filters do a great job keeping x-10 from being absorbed, just not that effecient at keeping noise from going back out to the power line.

    Do you have crawl space above that room? You could leave yourself a place to try different filters between the main and the power going down the wall to the tv and change it out as necessary. Just an idea.

    I don't have a large lcd tv so I don't know if this will work for that, but I use several of these on my large items http://www.automatedoutlet.com/produ...0&cat=0&page=1

    on my pond pump. my 2200 ups, the 10k btu window air conditioner in my equipment closet and the circuit for my office. You might also try the smarthome 15a plugin. You might be overloading the 10a plugin filter

    I have been happy with these. Being wired in you have to be creative in connecting them. I use either a metal junction box with pigtails or a multi gang plastic remodel box with a blank plate

    Here's a 500 watt model from Radio Shack for $160

    I switch the transformer off when I'm not using it since it draws about 20 watts unloaded.


    Wow, kind of a pricey way to go, but it appears I have no choice. Today I tried "double-isulating" the tv by adding a another 10-amp filter between it and the existing 10-amp filter. Didn't make a lick of difference. I also tried unplugging it completely and x-10 once again returned to normal. Darn. This tv is putting out so much noise that modules close to it are turning on without any x-10 commands being sent on the line. It really freaks me out and aggrivates me to no end.

    These isolation transformers remind me of a battery backup. I'm not sure a battery backup does isolation when it is on A/C power. The 20 watt problem doesn't bother me much, as, according to specs, this tv draws 20 watts sitting off anywho. Considering I paid over $3K for this tv, I think this would be one of the best types of surge protectors to use to protect it as well.

    Thanks for the great suggestion. Looks like that's the way I'm headed (and quickly).

Now, when that nice new hdtv is powered up, that entire circuit in my house becomes almost unsable.

    Unless I missing something, I thought that is what these filters were supposed to prevent. Do these filters only stop x-10 from going to whatever is plugged into them as opposed from stopping noise from these devices getting back out to the power line?

    Or has anyone had the filterlics just go completely out and/or quit working effectively?

    I was thinking of ordering a few more, just for good measure, but my home was working flawlessly for a long time and if these filters are not effective against this type of noise getting through, then I need to look for another solution to getting these tv's noise off the line.

    Any experience? I know it's sad I'm still on our old friend x-10...
    The filter "Helps" however it was not enough. My solution was to also add new non X-10 appliance modules. This stacked solution has been working without issue. I can not say the same for the Wii or Dell laptop power supplies but I am making progress.

    I wish to happily report that I put the filters inplace between the appliance module and the TV's and all works as expected now.

    Thanks for the help!

    I didn't even think of doing that. Duh. I wish I had seen this thread a long time ago. I've always wondered how to both control something with x-10 and have it filtered. I feel so stupid now... ha.

    Agreed on that one. I just always bought 10-amp (as opposed to 5). The ~$5 price difference is worth it, since I'm not an electrician and don't know how much crap I may want to plug into it (computer / home entertainment areas).

    Use of filters is one of those make or break decisions for those of us too poor to upgrade to the newer technologies.

    quickie ohm's law calculation (figures watts into amps)
    watts divided by volts equals amps

    so if it draws 650 watts, it is using (provided you are on 120 volt (USA)) 5.41 amps, so in this case use a 10 amp plugin filter

    The first step should be to plug the TV into a filter to see if that cures the problem. There are several to choose from http://www.automatedoutlet.com/_sear...age=1&q=filter
    If you put the filter between the TV and your appliance module you should still be able to use X10. It will look even dorkier then the appliance module alone, though, so hide it well.

    A short 'extension' cord between the two may help. Appliance module in the wall with short cord plugged into it. Filter at end of short cord, TV plugged into the filter.

    if they are X10 appliance modules a fairly inexpensive filter plug in between the module and the TV should fix you up.
