    Our TV is doing the same thing when first turning on it starts squealing and the picture will go out so if I play with it for about 10 minutes turning it off & on it will finally work for atleast an hour or 2 but it sure gets annoying and we didn't know what direction to take to get it fixed.

You have a bad colorwheel. No to uncommon. It is in the light engine and you should probably call a tech. Input your zip on the homepage to find one in your area. Let me know if I can be of further assistance

LG Tromm electric dryer model DLE5977B is making an extremely loud humming noise.


Humming is caused when the slow start capacitor on the motor fails. Better to buy a new dryer as the motor is usually around $160. Yours is $145. I suggest you take professional advice on such a high outlay rather than risking the advice of someone who hasn't physically checked the machine. I have two pro dryers in my hotel fail, and they buzzed.

Loud humming or buzzing only when it spins at high speeds


This noise causes by the drum bearing is getting worse. As soon as the noise is getting far louder and extremely louder then you have to replace the bearing of the outer drum. Normally, the repair cost is as high as buying a good deal new washer.

I have a pair of JM lab Electra 905 speakers, running through a DNM amp and power amps. When powered up, the left speaker makes a very loud humming noise. This has happened recently. I haven't changed...


Hello
Switch on your amp, keep its volue down to extreme low, and listen if there is still hum through the left channel or not. If still there is hum, the left side power amplifier section inside the amp;ifier is faulty. If htere is no hum at this state, hum enters thorugh the audio input terminal, and the input wires must be checked for open sheild connection. OK.

Noise coming from the rear end of my 2004 honda pilot it really only occurs during cold weather and after it warms up you hear it slightly


When does the noise occur, while driving only, or driving and idle, in gear, or in neutral and park? If it occurs all the time (while driving and at a stand still in cold weather) it could be the fuel pump. If it occurs only while driving, it may be a wheel bearing. Describe the noise (humming, grinding, whirring, etc), and what is the mileage on the Pilot? Answer my questions so I can fine tune my answer. Thanks!

Amp works on off on off


The buzzing is possibly the electrical mains hum at 50hz, all amps have a hum/buzzing... if you have to tap the jack lead between the guitar and amp it could simply be a connection problem, the cable may be old and internally damages, maybe loose wiring on the other side of one of the input jacks
