The surrounding area of the key board bounces and makes noises when used

there may be something stuck in between the tub and the outer wall, have you tried to make sure this area is clear first. Make sure you unplug the dryer first before removing the back panel, then use a flashlight to check the tub and surrounding area. id do this first before i go to the expense of replace the tub section

sounds like just the key switch has failed.
Check the connector, and make sure no pins have pushed out of either side of the connector.

best way to check shock absorbers i have found is to push down on each corner of car , very quickly but with most of your weight , let car spring back into position , if car rises fast and dosn't bounce up and down more than once or twice your shockies are o.k , but if car keeps bouncing 3 or more time's they are no good and will need to be replaced .

sometimes the spring that surrounds shockie has worn rubbers these can emit noise also ,
mainly sqeaking but if either shockie or spring is able to hit car body due to perished rubbers then knocking noise will occur.
check also that you dont have a cracked spring , i have seen this also , remove tire and visually inspect.

hope this helps .. good luck

Replace the crank sensor

It ur Vizio tv,The power supply board is the problems.The transformers in the power supply board have gaps in the transformers.The high voltage curents flow that make that buzzing noise.

Howdy: There is a spring loaded belt tenioner that holds the belt in place. They are plastic with steel bearings. They do go out often do to the surround heat in that area. Good luck - Doug

no, your shocks are not air. they are worn out. when you are by the car make it bounce by pushing on the bumper several times fast. If it continues to bounce 2 or more times then its time for new shocks. My avalanche is doing the bouncing thing now. Just dont have the money to replace the shocks yet.

The grinding from the brakes is probably the feeler on the pads letting you know they are about to be worn out. The feeler scratches the rotor to make the noise. When the noise stops then the feeler has broken off and you are about to be brakeless.

If they are computer speakers try this: (remember i am doing this from a windows vista) on the bottom right hand of the screen there should be a volume key right click on it and click on playback devices then right click on your speakers and click properties and go to levels and turn down the volume from there and see does that work... hope this helps.

under the compressor there will be rubber bushes which would have got damaged so change the rubber bush and ur problem may get solved

There is an audio board that needs to be rebuilt or replaced as this is a common issue with these Hitachi's. It is the surround board.
