Question about Flat Panel Televisions
My new Sony Bravia kdl-40v3000 lcd hdtv is making a clicking/crackling noise when it is powered off. It lastes for about one to two minutes. Is this normal? Do you know what it is? I had returned my first tv after about ten days because of this. Only to find that the replacement tv is doing the same thing. Any help is much appreciated. Thank you for your time. Marina
bravia after one making a clicking/crackling noise
I have had the same problem with my KDL-40Z4100. After having the power supply, various parts, and eventually the mother board replaced, i was eventually told by Sony that it is the TV Guide updating (it is NOT the cabinet nor anything else cooling off... the most I've had it off for is 4days straight - still clicks ). Sony Rep was very unhelpful (Sean at Customer Information Centre - 1-800-773-9667 ], and told me that even though i 'turned off' the TV Guide update - that it just turns itself right back on ( his words verbatim: "you cannot turn off the TV Guide update" ) -->ergo , clicking will never, ever go away.
This will be the last Sony product I ever purchase. Too bad, as I was previously happy with their products.
Do not waste your time trying to replace mother board / power supply / surge-protector, nor any other parts --> it is not a 'replaceable'-fixable problem ......

My kdl-46v4100 has been off all day and I've heard two or
three clicks. It sounds exactly like the click you hear when it’s been off all
day and you go to turn it on. A few minuets after it clicked I turned it on and
to my surprise there was NO click sound.
This LCD TV (like most large displays) uses an Active Matrix of thin film transistors, aka TFT. Essentially the screen is a large array of transistors and capacitors. According to my previous observations; I suspect the random clicks are associated with the LCD circuitry providing a fresh “standby charge” to the TFT array (hence no click on power on following a “refresh”).
Not a solution, but an explanation other than “cooling off…”

I had the same problem. I tried the 'disable TV guide' solution...didn't work. Then I reset the TV, but didn't enter a time/date. Clicking went away. When I turn the TV on, it displays a brief message to 'set the current time/date', but then it disappears. Everything works fine now...on my tv. (KDL-46z5100). My guess is that the TV guide needs the date/time set to determine when to obtain updates (causing the clicking sound).

I am experiencing the same thing. I am now being told by a Sony rep that the problem is the built in TV Guide feature when it does not receive a signal. Try disabling the TV Guide in the menu and see if this stops the problem. If it does not work on the first try you should reset the TV back to factory and again disable the TV Guide feature. I am going to try this tonight when i get home from work.

I was having the same problem on my KDL-46XBR9, clicking sound every 3/4 min when TV is powered off. Called Sony support and they asked me to upgrade the software and reset the TV to factory condition. He said it was because of TV Guide being on. Went through the initial TV setup but disabled the TV Guide. TV is back normal and its about 30min and I haven't heard that unholy/annoying clicking sound.

It is most likely the cabinet setteling as it is cooling off. Nothing uncommon with all the plastic that is used in TV's.

I have a Sony Bravia KDL-40W5100. My daughter purchased it in 2009 and gave it to me (2014) when she bought a new one. I also had the intermittent clicking when the TV was off. My 32" Bravia never did that. A search said to turn off the TV Guide and set my zip code to 00000. Initially that did nothing. However, the next day I realized I wasn't hearing the clicks anymore. It's now been three days of silence. I did futz around with Setup but not sure what I did. Man, is it hard to navigate. Anyway, all's well that ends well. The clicking was unacceptable.

SONY 52Z5100 Doing the same thing. A loud Click every 5 Min when off. This will go on 24/7 enough to drive one nuts. Sony replaced the mother board saying that was the trouble but the sound is still there. I tried turning off the TV Guide but it keeps going. The Sony Tech Rep? on the phome was not helpfull at all. Any other item I could return for a refund. Sony says I can't do that??

Also I have a Sony Bravia and it clicks while it is on as well. I read that forum and some people said to disconnect the cable box for 10 sec. and then some said it was the heat from the summer.. i don't know.. I just turned my tv off and then back on and it stoped. I read this is happening with all kinds of TVs....
