I have a 23" Polaroid CRT TV which is making loud popping noises every 15 minutes or so.
This has no effect on the sound or picture but scares my dog every time.
It seems to come from the left side (as you face the screen)
I'm having an issue with my 40" Polaroid LCD TV making a mysterious popping noise every so often. I'm curious to know what is causing this loud noise. It happens more when the TV is off. Other than the noise, the TV works perfectly fine. Weird.
My sony trinitron a very old model box tv makes a very loud banging sound ever 10-30 minutes on or off. Best way to describe it like a cracking or splitting wood sound. I'm guessing its from the plastic case around the tv its built with. It'll make that sound too when i walk near it and from my movement the vibration triggers the sound. However alot of times when there is no movement or anything it'll just pop so loud it'll scare the heck out of me.

Re: 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.

You have weak capacitors in the power supply and the signal board. I have not repaired this particular unit, but have experienced this with other Polaroid TVs. You will need a TV tech to replace those capacitors. It is a very time consuming task and requires patience and much care to remove the capacitors. Tell a tech that they must be very careful when they remove a cap in the signal board, as they can peel off a pcb trace. In most cases they replace the signal board, but the capacitors can be replaced! Thanks for asking and show a few hands of support!
my 46'' inch tv polaroid lcd has been working fine for 3 years. today my wife and I noticed the tv is shutting off the screen will go black and the power light does switch to red. you can here something inside the t.v clicking but you can turn it on and it will start back fine for 20 minutes then shut off again? Does anybody know whats going out on the tv? let me know
this sounds like the problem most LCD tv's get with swelled up
capacitors in the power supply board. look for circular cylinder shaped
parts rapped in plastic with writting on the sides, and metal tops, if
the top is rounded over, not flat, it is bad. replace them.
I purchased a poloroid tv 3732 in may of 2005 from circuit city, after about 14 months the set began making a clacking sound and humming sound that gets so loud it is unbareable. I have to turn the set off. I have found out I am not the only one with this problem that has a poloroid tv. I had a technician at my home that told me there is a service warranty on these sets because the wrong part was used and the part needs to be replaced.
