This looks like a compromise of insulation. I had this problem between the HV lead and the flyback transformer casing on an old Sharp CRT TV. Unsure of what to do, but fully aware of insulating principles, I stuck a rubber bookmark cover in between the lead and the flyback. The set works perfectly to this day.

Vizio SV47XVT 47inch Screen flickers and makes popping sound through speakers what do I need to replace.


This is a power supply and/or possibly inverter(s) board bad capacitors. Since the audio is affected it could be both. Be aware that attempting to repair it yourself could cause irreparable damage to your TV.

Samsung hlr5667w TV made a popping noise then the picture started


Most likely. You should remove the lamp door, pull out the lamp, and inspect it. Look into the center of the lamp, does it look dark or swollen? Does it look chalky on only one side? Did it burst? If so, you definitely need a new lamp. I hope this helps.

Loud popping noise


The 23" CRT set may have a high voltage breakdown in the flyback transformer or focus divider. Take the back off and operate the set in a dark room. Look for anything that has a blue glow around it or sparks flying when the pop occurs. I won't guarantee this will find your problem, but it is definitive if you see these!

I once had a set with these symptoms. I stopped the blue glow and arcing by covering the focus divider with epoxy. It worked for a couple of months before the divider literally broke apart.

Problem with Samsung HLP 4667W/HL DLP TV


As a general rule, popping sounds are bad news. This means a static charge, electrical shot, or insulation problem. Or a combination of these issues. Many times this occurs when the electrical circuit boards components break down and degradation occurs. In some cases a discharge of electrical energy (like when you get a shock from a door knob) may hop or jump between components and make a noise, whereby that popping sound occurs. In some cases, high energy discharges can cause an electrical fire, so be aware of the dangers. The fix can only be done by a professional with the skills to trace the problem and do a repair.

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.

Popping noise


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,

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.

Panasonic PT-53WX54 What is that popping noise?


A loud popping noise, like a sharp "snap!", is usually caused by high voltage arcing. Somewhere in the high voltage system an insulator may be cracked or loose, such as the plastic around the flyback transformer or one of the rubber cups on a picture tube. When the high voltage arcs, it momentarily drops and the picture could go out for a split second. High voltage is dangerous in projection sets so allow a qualified tech to service it for you.
