Question about LG 47LC7DF 47 in. LCD HDTV
My TV has a clicking noise when I first turn it on but after about a minute the clicking stops. I also am having problems with the sound. I have an HDMI cable from the cable box to the TV and then two RCA plugs from the Audio Out on the TV to my Samsung home theater system. Sometimes the sound just goes away. I tried connecting two RCA plugs from the cable box directly to the home theater system and the sound works fine.
I was told that these clicking noises (which happen on my Magnavox LCD too) were due to the "power required" at the internal switch. Seems that the power required to immediately turn on the TV is too much for a standalone household outlet, so it "surges" power in a series to get enough there. Hence, the clicking sounds are actually mini power surges to send more power to the internal circuits to turn the TV on.
If your set is like mine, these noises generally stop after a minute or two, correct?

the old saying is that any issues will likely show up in the 1st 3 days if you run it for 72 hrs. if it dosent fail then it will last.
other than going to the show room and seeing if their unit does the same.
they will likely want to send a service guy to check it out and decide for himself.
