We just got this 55" NS-55E790A12 and have it hooked up to an antenna. This tv takes 3 full seconds to change channels. Is this common? We have a samsung on the same antenna line and it changes channels instantly. Hate it that it takes so long. I didn't see this issue in the reviews.
2 1/2 to 3 seconds is typical for the Insignia sets I have used. Some older models are even slower. Most people use cable, so that's probably why you don't see anything about this in the reviews.
