Clicking noise sony bravia kdl-40v3000

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

    I hear a clicking/crackling noise when I turn off my new Sony Bravia KDL-40V3000 LCD Television. I called Sony Support and they told me that this noise was normal. However, I do have my doubts about this response when the tech person asked me if the sound was "audible". What a stupid question to ask. I can understand it if they meant "is it audible through the speakers", but I asked if that is what they meant and they said no.

    I had the exact same problem - it is the surge protector. Try plugging it directly into the wall, seems to take care of it. I ordered a UPS or uninterupted power supply from upsforless.com so it has protection. Hope this works for you.

    Removing surge protector did not change a thing on my KDL-46W3000. The initial clicking sounds like relay closing or opening. After 1 minute it seem thermal.

    Every time I turn my Bravia off it makes clicking sounds for a few minutes before it stops. Is this normal or is there a problem?

    I have the same problem with my new Bravia 46W4100. When I turned the tv off, it would make clicking noises for approximately 10-15 seconds. I followed the advice of one of the posts on here and plugged my tv directly into the wall-- this works! It no longer makes the clicking noises. Really odd, but I'll take what I can get.



    Has anyone had luck with a different surge protector?

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....

I returned mine also same noise you discribe. It sounds like relays at first closing/opening which would make sence but not after 30 seconds. I will try the surge protector fix. I do not understand how a surge protector would cause it.

Screen goes blank / black, sound still works


It sounds like your LCD Screen is no longer working. I would try contacting Sony and ask for a refund. I had the same T.V and the LCD Screen had gone out. A techniction came out and Condemned the screen and i had to pay $500 for a new T.V.

Tv bravia kdl 40v3000 problem turning on


To wayne: The balancer board is in fact available by itself. You can get it at many different parts depots here on the web. I just suffered from a similar problem, on the same tv and it solved my problem perfectly (Stupid 13 blink, blink code...)

The searchable part number is SSB400WA20. Its referred to as a voltage inverter (for the backlight of the lcd panel.)
Good luck!!!

Clicking noise sony bravia kdl-40v3000


Normal 0 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…”
