Loud Cracking/Popping Sound

My Samsung HLP4663WX will intermittently just have a loud popping sound. Sounds like something is cracking in the back of it....but there are no problems with my TV otherwise. Just that loud sound...I'm curious to find out what it is? Should I be worried? Anyone know anything???

Thanks
TC

    Thanks for the help accordianman. Is this common? Is there anything I can do to try and make the sound stop? It's a very loud noise. When people are in the room, they jump if they aren't used to it...

    It's been on the stand for several months...it's secure as far as I can tell. It sits on a Bell'O stand which is made of tempered glass. Only makes the sound when the TV is on. It's annoying!!!!!

    [B]I found a solution to the sound problem, which was causing popping and static sound from the speakers.[/B] This was also shutting down the audio after watching TV for some time. I place a heat sink on IC 987 part number stv8258DSX. This IC controls the sound and is overheating. The cause is unknown to me. Its easy to place a heat sink. Direction: cut the heat sink to size allowing room for a nylon nut. make as tall as possible. drill hole in center, but drilling only to its center, not through it.. Use nylon screw and nut (plastic). Insert the screw through the hole in the grill cover metal and than thread the nut to it. place the heat sink on top of the IC and place the grill cover back on aligning screw in the hole. (Don't forget to use thermo compound between the heat sink and IC). pull up on the screw while turning clockwise to tighten. I left the TV playing all night to the next morning and sound remain normal. I even turn on SRS sound mode.

Any other symptoms? You may be just hearing the occasional sound of static being bled off, or, if the set is not working properly, the sound of the high voltage section trying to compensate...accordianman

What could cause loud popping sounds?


The sounds you are hearing is the defrosted water, from auto defrosting, running onto the hot compressor. This evaporates the defrosted water. This is quite normal.

I have an 05 Mazda 6, when my car is while idling it makes a loud cracking/popping noise.


A cracking or popping noise is frequently an indication of an air/fuel mixture that is too lean (too much air). Have a mechanic or mechanically inclined friend check the various vacuum lines on your engine. Sounds like a cracked or broken vacuum hose on the intake side of the engine. Good luck.

When pedaling starts off making squeaking sound but now it is very loud with cracking and popping.


Pedal or bottom bracket bearings need a look. The web has many resources for identifying noises on a bike. Just search for a few key words. For example "bicycle pedal loud cracking and popping"

One resource...

Heard a loud cracking sound and the screen to my Toshiba plasma 50" went dark


The popping sounds are bad capacitors arcing at the high voltage input area. You need to change parts on the power supply and repair the high voltage control card located on the X-sustain..... or you can just order a new power supply board and X-sustain here: CLICK

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.
