When you say popping, was the sound coming from the speakers? or from the back of the set? My initial suspicion would be power supply capacitors.

Might be worth the effort to open it and have a look for loose plugs or a ribbon cable somewhere--if do look for any plugs that are held down with tape near where they plug in.

Pop sound and now no picture or sound still gets power


Try disconnecting all the cables from the TV then reconnect them after a few minutes. It's suggested that you connect the power cable from the TV directly to a functional wall outlet.

If still there is no picture on the TV then it's required to replace the projection lamp.

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.

When The HDMI cables are connected, I use Directv, I have just recently started to have the picture come on and then start flickering and various color bars pop up on screen, then the screen will go black...


It is possible that the HDMI cable is defective. Did you try another cable?

It is also possible that the HDMI port on the TV is failing.

This can be determined by the process of elimination.

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


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.
