Dimming Lights in HT Room

[MikeD105]

So I've recently come across two cases where I'm seeing dimming lights in someone's home theater room.

Now these aren't dedicated theater rooms per se, but rather living rooms which now home HDTVs, receivers, etc.

In case number one when the television is powered on all of the lights in the room dim for a second or so and come back on.

In case number two while the television is on, the lights will dim on a fairly regular basis until the tv is turned off.

In both cases a standard run of the mill surge protector is in use and in both cases the lights in question are high hats in the ceiling.

Is this something that a power conditioner with voltage regulation will fix or is this something that an electrician would have to deal with?

Your help is appreciated as always.

No a voltage supressor will not fix that. I would say there is a bit too much draw for the size of breaker for those HTs. Are we talking direct view CRT TVs? Because I have a CRT and when I turn it on there is a BIG draw from it. Most flat panels these days draw a lot less current than a CRT.

Good question Mike.
It's certainly something an electrician would deal with.
Sounds like the lights and receptacles are on the same circuit.
The way that is remedied, is by having a dedicated 20 Amp circuit or two, installed for the HT equipment.
There is no exact limit in the NEC, for how many receptacles can be on one circuit, for rooms like bedrooms and living rooms. So, one never knows what else is attached to the same circuit as the TV.
