Popping I just bought this tv today and hooked it up. Now it is making a popping noise. I have tightened the cable connection to it and still have this popping. When it pops, the screen shows a small white bar. Do I need to take it back or what?

you must have a wire ( sound plug ) not connect properly ,
sometime those plug loose with time ,
when powered the make connection and those sound happen !

i will put a pic here on how to connect the 2 tv-s


good luck!!!

YES.. 100% Not acceptable at all.

You have a problem indeed. try lowering the tv volume . if the signal is too high on tv it can cause some problem with the sound system if that dosent work then you may have some electronic sound output resistor 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.

Our Sony (almost new) is experiencing sound problems. The sound go off and on about every 10 seconds. Cords appear correctly connected. It sounds as if its coming from the television.
Can you help with this problem?
Thanks,

Mike

Has anyone heard of something like this where the cable box/service is causing popping sounds? yes & it is common problem. And is this something I should be concerned about causing damage to the TV's speakers? not at all. The Sony tech-support representative (over the phone) diagnosed it further to a problem not with the TV but with the cable box/service because there were no popping sounds when I played a DVD on my Playstation 2 that is attached to the TV. they are right that your problem is not due to tv. it is due to cable box/service? yes but not defective it reqires to change the way you have connected tv to cable.please call tech to get it connected in such a way so that you do not get popping sound when you you put off cable box.

If the popping sound is NOT coming through the speakers, you probably have high voltage arcing. Probably close to the high voltage (flyback) transformer. If this is the case then other parts could be damaged if allowed to continue. If the popping is coming through the speakers then you could have a problem any where in the signal circuits. Like a loose connection. You'd need to have it checked out to find the problem.
