How to SOLVE Slow Channel Change on Brand New TV's?

Need to know; was the old TV an HDTV?
Newer TV’s need to “handshake” with the cable system and that takes time.

Other tv that works fine is a 2009 Samsung HDTV

Is waiting 3–5 seconds for a channel change so onerous?

I have a three-year old Sony HDTV 46“in my basement family room; it does not get Fox TV.

Up two flights of stairs I have a new LG HDTV 42”... Fox channel comes through just fine. The guy I bought it from could not explain the phenomenon.

Both are hooked up to a loyal and sturdy roof antenna installed in 1986.

What is the refresh rate of the new TV set? I find 60 Hz sets are slower in changing channels than 120 or 240 Hz refresh rated televisions.

Does your cable use a universal remote? We had to have the cable company come out and recalibrate (or something) the settings on the cable remote, and that did the trick.

What brand is it ? My TV takes some time to change as well, but that is from a lesser known brand, it changes in a bout 2 seconds, and i feel that is slow for me, 5 seconds would be slow for any TV.. are you sure the problem is not in the cable/decoder area ?

And
I would say that your old TV was a really smart one, since it bought a new TV on its own :)

I bought the new TV from BEST BUY. Sharp – AQUOS – 60” Class (60” Diag.) – LED – 1080p – 120Hz – HDTV

I am not paying for cable. I just plugged in the coax to the tv and it was on there. I do not want to start paying for cable. So I can’t call the cable company. And I do not have any decoder or cable box.

@gailcalled The VHF band receive on your TV likely has issues. Fox is about the only channel that uses VHF
