Without tracing the audio path with a scope, this would be difficult to guess at. It is very likely that there is either a cold solder connectoin, or a component failing in the son circuits.

Popping sounds only during video/ you tube on tv from my computer.

Because of the amount of voltage required to run the older-style "tube" televisions, many problems, sounds and noises occur in tube televisions than in the newer, flat-panel televisions. Sounds occur for multiple reasons, with some being just part of the normal process these televisions run through in order to operate. On the other hand, some of these noises may indicate a problem with the television that could warrant repair.

Worn Insulation
Voltage against metal. Inside your television's tube, there are many wire parts that electricity runs through in order to make the television run. Usually, these parts are insulated with a rubber or foam casing that prevent the sound of the electricity. If the insulation surrounding these components is thin, weak, worn or absent, you are bound to hear buzzing, popping and cracking sounds coming from your television. While this may not mean you have to run out tomorrow and get a new one, the chances are that your TV's tube is working extra hard to make it all happen for you, and you may want to start pricing new sets for the near future. b> Static During Warm-Up b> Just like rubbing your feet on a thinly-carpeted floor can cause static electricity, the same can also build up inside your television. If the noise is relatively subtle, only occurring when you first turn it on, and not overly-disturbing, the chances are that the cracking and popping sounds you are hearing are just the television's way of warming up and getting rid of the unnecessary electricity. Bad Lamp b> Deep inside the heart of your tube television, there is a light-bulb fixture that makes the entire unit light up so that you can see a picture. If the cracking and popping sounds you are hearing tend to go along with the picture on the TV becoming unclear, it could be that the picture tube is failing. It is very difficult and costly to replace the picture tube on a tube TV, so this is an instance where you may benefit more from buying a new television than taking the old one in for repair. Hope this helps.

What causes the static background noise in my keyboard?


It sounds as though you have a static electricity problem in your volume pot. Although there are sprays on the market that you can use for all of the electrical switches on your keyboard which removes and suppresses static electricity, one way to make sure this is the problem is to slide your volume slider to maximum, then minimum, up and down about 10 to 20 times, if the scratchy sound begins to diminish, you knwo the problem lies there. As a matter of fact, if you do it long enough, the sound may go away altogether, although without a good spray of electronics cleaner or electrical contact cleaner (which you can find at stores like home depot or online, even eBay), the sound will return.

If this is not the case, and the scratchy static sound does not go away or depreciate, it could be your cords or even static on the pc board inside the unit. If you are confident that you can crack the case on your board without causign damage, then get a screwdriver and open the case (all screws are located on teh bottom of the unit) and give it a good spraying with electrical contact cleaner on all of the contacts and even a once over on all of the circuit boards. Do not wet the circuit boards with too much spray, rather, give them a light misting.

For areas where you plug in, like your 1/4 inputs, your midi ins and outs, and headphone jack, spray the contact cleaner inside the holes. You don't have to worry about spraying too much in these areas. Just do not oversaturate.

Hope this helps, and thanks for using FixYa

Insignia PC speakers - give a weird static feedback noise

I'm going to vote for the haunted option.

Sound like you have some noise on your power lines. This can be caused from many different things. Normaly it is a motor going bad or a compressor starting up. From the AC unit or refrigerator.

See if you can correspond the noise to anything else happening in the house. Fridge starting up, AC or heat cycling on...etc.

It may be that you just have speakers and a cordless phone going bad at the same time.

It might just be Casper the friendly ghost playing tricks... ha!
