42" Panasonic TV cutting out when turns off for a second when our microwave is turned on or our overhead sunken ceiling lights are turned on or off. We have put a conditioner on the TV plus a separate plug just for the TV and it is still doing it. The TV is only a couple of years old. It is hooked up to a satellite receiver which is about 8 years old. Could this be the problem?

How long has your TV been doing that? Has it been doing that the 2 years you have had it? Or it just start? Are the recessed lights or the microwave on a separate circuit?

Yes they are. We got a conditioner for the TV and have it on it's own separate line and the microwave still bothers it. Had industrial electricians in and called Panasonic plus the very reputable dealer and they keep saying it has to be something with the electrical but can't seem to find the problem. Could it be my friggin' microwave causing this problem with maybe infrared lighting?

I'd really like to know if it's on the same circuit or a different circuit. The microwave and the lights make a large current spike which may be lowering the voltage because of a poor connection "Somewhere". That somewhere could be a single outlet or at the breaker or at the main panel.
A constant voltage transformer MIGHT work, but it's not the right answer.

Is it just the microwave?
If it is, place one of these on the microwave circuit. http://www.tripplite.com/EN/products/product-series.cfm?txtSeriesID=74&EID=81
There is a direct plug in model available too. You place the surge/noise suppression at the source rather than the destination.
I the lights are bothering it, then I'd look at connections such as the main lug and the circuits involved.

We have already have done that. Can an older satellite receiver be causing this problem, where it is much older than the TV. We have had all the pro electricians that we know ask us this. Before we commit to brand new receiver, we would like your opinion. It does not happen to our newer TV in our bedroom which is connected to the same year,brand etc. receiver.

The surge suppressor MUST have an RFI filter Not all do.

They are on different circuits, the microwave and TV. We have had two very reputable electricians in to check this out plus the one put it on it's own plug plus a new breaker, plus a very expensive conditioner and still the problem is occurring. Hey these guys are good, they probably could tell you how Jesus walked on water, but that's not what we want to know. When we have anything else in the house running the TV will stay on forever without a problem... so it's not the TV... HELP!! Keep thinking, ask your buddies. We have had the TV checked out and it is fine and dandy!!

What is an RFI filter? This conditioner came out of a very modern new tech automotive facility... couple of years old if that... they ran the PCL's, so this sucker should handle a friggin' TV.

What's the model #?
RFI is radio Frequency Interference
The supressor should have common mode and normal mode suppression as well.
Don't put it on the TV, put it on the microwave.

Thanks so much for your help... we will give that a try.
