Clicking noise after powering off sony kdl-40v3000 lcd hdtv
by futurerichone - 10/26/07 6:50 AMHelp! I have a new Sony kdl-40v3000 and would like to know if it is normal for it to make clicking/crackling noises after powering off? It lasts for about one to two minutes. I had returned my the first one I purchased after ten days, but now this one is doing the same thing. It only makes the noise when it is powered off and it lasts for about one to two minutes. I hope someone has answers for me. Thanks. Marina
Clicking noise after powering down Sony 40" LCD
by seb222nr - 11/9/07 1:59 PM In reply to: Clicking noise after powering off sony kdl-40v3000 lcd hdtv by futurerichoneI have the same set (the Costco kdl-40vl130 version) and it does the same thing. The owners manual does make mention of this noise on page 5 or so. This is actually my third sample of this model. I returned the second set because I thought the popping was a sample defect. The first one was returned due to intermittent sound. That issue, however, appears to have been cable-related. The strange thing was that those times I turned on the Sony and it was silent, switching inputs did not bring the sound back. After the sound began breaking up with the third and current set, I had the cable guy came out. He moved the Sony off of a cable amplifer, saying that signal output was too high. Sounds fishy to me but I haven't lost sound since he did that. I don't recall the clicking and popping noises with that first sample but it could be that I wasn't paying attention. It was a while ago. I have occasionally noticed the noise for a minute or two after powering up, as well. It appears to be metal and plastic heating up and cooling down. It does not appear to be a sign of impending failure and I have seen postings about this type of noise with other brands in avsforum.com.
Clicking noise after powering down and/or no sound
by Wasn't Me - 1/9/08 12:24 PM In reply to: Clicking noise after powering down Sony 40" LCD by seb222nrI have the same thing on my 37M3000, both the clicking and the intermittent dead sound from the tv speakers. I am calling in a tech for the intermittent sound/speakers cutting out and staying that way. I have it connected to a digital cable box. When the sound cut out completely, I connected my stereo to the audio out of the cable box and the sound worked
I know what it is

It is the surge protector - just plug it in the wall and it won't do it anymore. I was told to use a UPS or a uninterupted power source that they sell at costco.
I have the KDL-46v3000 and have no popping sound

crackling and popping noises on HDTV when turned off
by ericanderson123 - 2/28/08 2:47 PM In reply to: Clicking noise after powering off sony kdl-40v3000 lcd hdtv by futurerichoneI had the same probem - very frustrating - it is the surge protector
Plug it into the wall and it doesn't really do it anymore (just a couple times). I ordered a UPS from UPS for less.com so it has some sort of protection and it has an uninterupted power source.
I'VE ENCOUNTERED THIS SLIGHT ANNOYANCE WITH BOTH............
by Riverledge - 2/29/08 7:36 PM In reply to: crackling and popping noises on HDTV when turned off by ericanderson123MY SONY CRT & PLAMSA (very rare,) PANASONIC EXPLAINED THAT THIS WAS NOTHING
MORE THAN NORMAL HEATING/COOLING NOISES OF THE PLASTIC SUBSTRATES,
AND PLASTIC HOUSING.
THIS ISSUE NO LONGER EXISTS, AS THE HDTV HAS BEEN IN USE FOR ABOUT A
YEAR.

I got it too - I'm thinking power supply - Try This!!
by loachspit - 1/31/09 11:08 PM In reply to: Clicking noise after powering off sony kdl-40v3000 lcd hdtv by futurerichoneI get the crackling noises too after powering off my TV for ~2 min. None of my friends have HDTVs that do this. I noticed after powering the TV On (and placing it on mute) I also hear a few cracks and pops, but it's not as pronounced as when I power it off.
Anyway, I tried something and I think I pin-pointed it to the power supply (or the TV at least). If I turn the TV off, and then unplug the AC power cord from the wall, the crackling and popping is gone! That would indicate that it's not a thermal expansion / contraction issue. It points to the TV and, from what I've read, more specifically, the power supply.
