Why does the screen go black when gas range spark igniters fire?

My tv screen goes black when the spark igniters for my gas stove are activated. This is a new problem. The stove and the tv have been installed for several years with no problem before.

Hi,

Seems as though the EMR ( ElectroMagneticRadiation) produced by the ignitors may be interfering with the TV signal.

Has anything been changed at all, for instance the location of the TV, which power outlet it is plugged into, the TV aerial location? What is the model number of your TV and also your gas stove?

Does the screen remain black or does in come back within a short time? Do you have to turn the tv off and back on again to get the picture back?

The screen is black only for the few seconds that the igniters are firing, then it recovers immediately. It's an LG flat screen. I haven't changed anything as far as location, etc. etc. The TV is plugged into an outlet that is on the same circuit as the stove, but that has always been the case. I have checked the grounding on the circuit and it checks out ok. The gas stove is a Kenmore.

Whoa u should be very careful like who knows what's gonna happen

Idk about that I mean it would be best not to ask me cause idk about that I mean that's bad it should go to junk

Hi,

I would check the aerial cable connections to the TV to make sure that they are in good condition and not loose. Also if you can, use the signal strength diagnostic feature usually found in the menu of a digital tv to check the signal strength and quality level of your TV channels signal. If the signal is of lower strength or quality it is more prone to interference than a stronger signal. It may be that there is a problem with your antenna cable or perhaps there is a something new between the transmission tower and your aerial that is partially blocking the signal reducing your received level.

If you have a second TV check the signal level that it is receiving and if it also prone to the interference from the ignitors.
