Question about Sony KDF-42WE655 Television

2 Answers

Popping noise, about once every 24 hours, no change in sound or picture.

The popping noise started soon after the optical block was replaced because of blue screen on the lower left side of the screen.
The TV is not as bright as when it was new ( 2004 ) and the lamp has been replaced, but did not make any difference..
No codes are left on the Red or Green Indicator lamp.
Also, the popping noise is not as loud as the first ones.

    Answer to Questions:

    I did use a SONY Lamp, however, that lamp has since been removed and the original one put back.

    There is NO visable change to picture or audiable sound cvhanges.

    I have not cleaned the Mirror.

    I cannot tell exactly where the popping sound is comming from.

    Sometimes it takes from one to four hours before the pop sounds.

    This set has also had the " B " Board replaced, as well as the Optical Block, but not at the same time.

    Thanks,

    jawaik

    A couple of questions:
    Did you use an original Sony lamp when the lamp was replaced?
    Does the pop correspond to any changes in the picture (change in brightness, picture jumping)?
    Can you tell where exactly the pop is coming from?

OK the brightness issue may be from putting the old lamp back in. If not, I'm unsure what could be causing your loss of brightness.
In terms of the popping noise, there are many things that could cause a popping noise in the set. The one I worry most about is some kind of electrical discharge., probably related to the lamp driver or lamp ballast. I have seen the high voltage leads that run from the lamp ballast to the lamp socket turn brown and degarde to the point where the insulation falls off, make them a prime candidate to short, causing a popping sound. I would expect that to show an error code though in the form of a flashing red light. It could also be some kind of expansion noise within the cabinet. I would be interested in having you try this:
With the power off, press the following buttons on the remote control:
Display
5 (the number 5 on the keypad)
Vol - (or volume down)
Power

You must use the original remote and press the keys within 2 seconds total. Then read off any items that show a 1 to the right instead of a 0. I will wait for your response. If you found this information aswered your question, please be sure to rate the solution. Thanks!

    No errors indicates that it PROBABLY is not a high voltage pop you are hearing. Without actually being there to hear the pop or knowing where it came from, I'm afraid I can't tell you much more. I'm sorry you feel the best I deserved was a thanks for trying; you must understand that I am operating under the above listed restrictions. I hope that you get your problem resolved and if I can help you further, please let me know.

Check all of your ground screws on the boards that you replaced. Sounds like that once the set is getting hot, the board is expanding and shorting out on the screws.

TV LG Model 50PX1D-UC Flat Panel Television Loud Popping Noise. TV goes out. I turned on my tv the other morning and it let out a loud popping noise and the picture went out. Any suggestions...


Hello,

The problem is that there is a bad capacitor inside the unit, it is either on the main panel or the power panel. The popping sound you got was due to the fact that the lead on the capacitor was bridging, therefore causing some electrical popping sound.

Run a check on the main panel and the power panel for any bad capacitor and replace it with a new one. That way, your television will be in good condition once again.

Take care and good luck

Sony Bravia XBR-2 32-inch LCD with popping noise problem


Unfortunately, we have the same problem. We hear popping and our sound goes lower. It is not the cable box for us, it's definitely the TV; however, it happens, on our set, after its been on for a few minutes and then goes away after half an hour or so -- however, this evening its been happening for the past hour and the TV has been on for the evening.
