Humming noise


Possibly a bad cable or bad ground or bad outlet?. Easy solution, try a different outlet and see if the hum still exists. Also, make sure your speaker cables are NOT run parallel along with, or close to any power cables, Speaker wires can and will pick up AC "Humm" noise.

Reason for humming noise even after changing wheel bearings of car


Depending on how the noise is affected by your driving, it could be an axle joint or the differential in the transaxle.
If it is coming from the back instead of the front you may still need hub bearings.

My TV makes a humming noise and the display on channels that are broadcasted in HD is not working.


the reason for it not displaying HD channels would be the Tuner itself, The humming from the back would be a fan that is dirty from dust or its is given out.

solution for the humming clean out the fan! check fan to amke sure its doing the right RPM rotations per min. For the tuner this would need to be looked at and tested by a Tv repair person.

Hum in the audio - 32'' Proscan 1080i


does the hum occur when playing a dvd or only when watching tv ? if the hum occurs only when watching tv, i would like you to disconnect the cable line from either the wall or the back of the cable box and see if this hum disappears. if the hum disappears call your cable company. you have what is called a " 60 cycle ground loop ". hope this helps.

I replaced the light bulb, now it displays -F6- and pushing any button causes a humming noise.


I left the unit unplugged over night, plugged it back in the next day and still had the same problem.

Bought the display unit and water will not work.


hi there the low humming noise that you are getting sounds like the fill valve, this could be due to you perhaps not turning the water back on after fitting the new dishwasher or the fill hose being kinked when the dishwasher was put back ,hope this is of some help to you.
