Re: My LG RU44SZ61
This may be caused by the high voltage arcing inside the set. This is most commonly caused by dust buildup on the electronics. A thorough vacuuming, with the set off & unplugged, may cure the problem. Use care not to disturb any of the components inside, as many are delicate. Compressed air(30PSI max.) may also be used.

Mine does the same thing. It makes a regular popping sound that does not change in level with the volume control. When the popping starts getting erratic the pixelated sound starts and in a short time the sound straightens out for the rest of the viewing time. However, the next time the cycle repeats itself. Did you find a fix?
The loud pop you hear is a spark gap being jumped. That might happen once an awhile naturally due to a voltage spike but if it's happening regularly chances are something needs replacing. Capacitors are prime suspects for aging, in fact when a capacitor(big one) blows it sounds just like that.
Yes. Its probably a stuck button on the TV's front panel. Try pushing or wiggling each button on the panel. It could be the channel up/down buttons or volume up/down, menu, etc.
When there is a button that is making slight contact, it keeps the microprocessor busy attending to the command its erroneously receiving from the offending button and may not allow other functions to work when this occurs.
It doesn't matter which button is stuck, any of the symptoms you describe can happen.
The problem is the software in the television. Very commom problem in these sets. You can have a software update done and this will solve the problem. Normally an LG authorized technician has to perform the update. I don't think the software is available to consumers yet.
Turn down the volume and see if you still hear it,a loud pop or snap could be high voltage call your servicer in your area ASAP
while its under warranty and have him check the high voltage circuits for a intermittenting pop or snap.And have the model # ready!! Good Luck!
it sound as the menu button is staked, is a easy job for a tech, but dificult one for regular people, better get a tech and let him know that you know the problem is the menu button, thas gonna help with the price off the repair...good luck
The input source such as the cable or satalitte signal my be a bit weak or the set may have a problem with the streo sensitivity. This is not an adjustment that a consumer can do. Have the cable checked out also. Goood Luck
