Hi Cyrus: There are a number of ways two TVs can interact with each other. But I think we have narrowed the problem down to a different factor. We (I had to consult on this one!) have two working senarios. One is that perhaps the new TV is not set properly to receive cable. Usually there is a set-up option for this. Verify and make sure that the TV is setup properly. The second scenario is that perhaps the cable signal level is too high for the new TV, on the high channels, and when you turn on the second TV, that it reduces the signal enough so that the new set can lock on properly. That scenario is based on an assumption that the cable company uses pre-emphasis on high channels (increases the power on high channels) to compensate for the losses, and that the levels of pre-emphasis are over loading the new TV. The official recommendation for this is to call the cable provider for service. The unofficial thing you can try is to put an attenuator in series with the cable hookup and the TV and see if the TV can lock on. You can buy such attenuators from the stores for a couple of dollars. Or, alternatively, and this is officially not recommended, you can put the new TV on a channel that doesn't lock (with the old TV off). Then disconnect the cable wire from TV set. Then slowly touch the center wire from the cable to the center conductor of the TV cable jack, but don't install it all the way. This should, in effect, do the same thing as the attenuator, which is to reduce the signal level getting to the TV. Hopefully it will lock, and the problem will be solved. Either case, I would recommend placing a call to the cable provider service department and presenting this problem to them, and see what they have to say. Then I recommend you tell me, as I'm very curious to see how this turns out. Awaiting your feed-back. Abtin Spantman SPANTMAN@EXECPC.COM
