Whenever my fridge starts in my 5th wheel I get the sound vibrating in the tv speakers? What should I do?

turn the thermostat all the way down it will turn off system

Tighten the screws hold down the offending speaker. If all the screws are tight, and the offending sound continues, the speaker is defective and may have been damaged by over driving.

the steering wheel shaking at an idle is a whole seperate thing. if it shakes while idling i would say its a bad motor mount (or mounts)
If the rubber breaks or wears out in the center of the mount that the engine bracket bolts to, then the center of it lays closer to the metal outer shell of the mount from the weight of the engine. The outer shell is bolted directly to the frame so it resonates vibration through the frame and body instead of 'floating' in the center of a rubber cushion.
Once your accelerating the engine rotates up in the mount lifting the center off of the shell so the vibration goes away.

This tv have a colors wheel,it dead.Require changing.Humming or vibrating sound,Flashes pictures black&white.The colors wheel is dead and it not spinning in it axis motor correctly anymore.Hire a tv Tech. to change the colors wheel,it very hard to change the colors wheel.Because u have to take out many machanical parts,even before u can get to the colors wheel itself.

Probably a wheel bearing

Check your u-joints in the rear driveshaft.

The speakers on the Sansui aren't very good. Its better to buy a surround sound speaker system to compliment your tv.

looks like the color wheel its bad in the set,color wheel its not spining at its proper speed( one of the segments may be broken)
thats the vibration you are hearing.. and the set its trying to turn on..until you replace the wheel you will be able to watch tv again.

Replace the main board and it should correct this, if it did it all the time I'd say its a bad speaker but since it works ok to start with sounds like a bad audio output chip in the main

do you have 5.1 speakers with built in amp?
