Hello. Most plasma's do have internal fans that keep the temp down on the internal components. Maybe you have not noticed it if the tv volume was turned up. It also could be that tone of the fans are defective, which would cause them to sound louder. If it is unusually loud, you might want to have the t.v. checked. I hope this helps. Don't forget to rate me if I helped you. take care. Ron

Lg 50pq20d plasma tv not switching on but voice comes out


Aside from checking the fuses it likely will require a technician or a shop to examine the set to see what is wrong and what needs to be replaced.

Sounds like a power supply issue but that would need to be checked.

After loud cracking noise no picture on plasma


The most likely the TV has a power supply related problem. A power surge can cause the problem. Last thing you want ot do is void the warranty by opening up the TV. Here's info to get your warranty started:

LG 50inch Plasma received loud sound then went black


I suggest you guys take your TV's into a repair shop like Sears or Best Buy... The main reason most plasmas go dark is because of decay, but I don't think this is the case. Because what you describe is similar to what happens in LCD's when their back light goes out. Although you can open up and repair the back light your self in a LCD, I would not advise you to do so for a Plasma, because of the hazardous chemicals used in the plasma display plus the fact that plasmas don't use back lighting. And 2 years is way to soon for decay to be a factor. So more than likely a circuit shorted out and the TV has to be opened up to be repaired.

This is almost certainly the device that sends electricity to the the plasma in the panel after failing. Bring to your local repair shop and expect to pay 300-400 parts and 100-200 labour.

LG plasma tv made loud popping noise


The plasma gas tubes may be damaged or the gas couldve leak out. remember plasma have to remain upright at all times even when transporting them, if they are not you should just set it up straight for about 3-4 hours before turning it on.

42 inch LG Plasma TV - Lost picture


Hi , I recently had the same problem which I was determined to fix . So I did a few weeks of research to find that it was the Y SUS board which burns out. I'm sure you realized that the TV gets hot. Personally I think this is why. circuit boards don't like heat and I've learned that the cooling fans are a joke. I replaced the board and got my picture back. I proved the fan theory because after the screen started to act up. I placed a cooling fan near the vent holes on top and the problem cleared right up,It also helps if you lower the brightness which helps out on the heat situation.I will soon be adding a fan with a temp. sensor. This shoud help if your screen has lines when you initially turn the cool TV on.then I have Some other costless solutions. Hope this helped these are great TV's and like our cars we maintain them not throw them away..................................Mr Wiseman

You should call for warranty service. If the set is very new try to get it exchanged.

There are some very heavy duty power supplies and many high power matrix drivers used in Plasma sets.

The description sounds like the noises are very loud. It is normal with any of these TV sets, if you put your ear right up to the back of the set at the vent holes you will hear some noises. These would be some acoustic harmonics from the power supplies and related circuits.

I am wondering if it is possible that there is something that is becoming less stable. If the set is working very well without any failure, so-far this is a very good sign. Before it gets to be a problem, I would have this checked.

On many models of these sets, they use fans for cooling specific areas. A bad fan can cause noise.

The popping noise you heard it's probably a capacitor blowing up in the power supply circuitry. If the TV is less than one year old, still covered under manufacturers warranty.
