There are six small (50mm x 50mm x 10mm) thermally-triggered ventilation fans inside the unit. in time the bearings in these fans wear out (prematurely?) and cause an annoying whine; was told by service person at first replacement that premature bearing failure is result of mounting orientation. whine can drive dogs crazy when sound signal muted. people too. hopefully relatively easy to replace fans if careful; will soon find out when new fan ordered arrive. replacement cost from Sony for fans is almost $50 each as of 6/1/2008

    well, if tv set gets very hot, it will turn off automatcally as protection. I think, nothing is wrong with your tv and please check its connecting cables towards DVD player or some thing like that.

What causes our front loading washer to make exceeding loud noise when it enters a spin?


Sounds like a bearing seal is going. The seal has ruptured and grease of seeping out. The loud noise is the bearings rubbing against each other without adequate grease to reduce the friction. Failure will come soon if it is not fixed. The vibration is coming from the friction and possibly damaged ball bearings .

ASUS Lap top computer, 2 months old' makes loud fan type noises at each start up.


Hi

Its normal for a laptop computer or a desktop computer to spin its fans at maximum speed during start up - its part of the power on self test.

If the fan is very loud like on this video the sound is very bad -


that would be a bad fan, constant bad noise. but if your fan only makes noise in start up, its normal.

your warranty should cover the replacement of the fan if its bad.

Vfr 400 nc24 whining noise when engine is reved


The loud whining noise is just normal for vfr 400 because it is gear driven cam.. As you reach 5000rpm up, the bike's electrics try to misfire the plugs so it would act as a speed limiter (180kph).. You have to bypass the sensor at the speedo..

I just bought a 2005 royal star venture. It's a great bike. The problem is a gear noise very loud when a ride in a constant speed. The noise become very loud and it very unpleasant after more than a hour....


Hi: It is "normal" for most royal star ventures to have a loud chirping sort of gear noise at certain rpms. Mine does it in every gear. It is especially noticable at between 100 and 110 kms/hr. If you increase or decrease the speed it gest better. This noise is because of the straight cut gears. Yamaha does this for strength and reliability but it is annoying. You can read more about it on the Venture owners sites such as The Venturers or VentureRider.org. It is nothing to worry about but I know it is annoying. Mine does it too. The RSV has a few quirks like this. nothing serious but somewhat annoying. THe other common thing is that the speedometer reads about 7% high. Mine does and many do. However, it is a very smooth, and very reliable bike. Hope that helps.

Samsung 2253bw lcd monitor makes loud, fast ticking noise > 10hz. Noise occurs even when monitor is powered off with switch.


Turned out ticking noise was harmonic vibration triggered by a nearby airconditioning compressor. Once I guessed the cause, putting a rubber pad under the monitor to dampen the vibrations eliminated the ticking. Removing the pad caused the ticking to reoccur. Ditto with turning the A/C off or on. Weird!

Computer making noise


Monitor clicks, pops, or makes other noises. Issue: Monitor clicks, pops, or makes other noises.
Cause: This issue could be caused by any of the below possibilities:
  1. Monitor degaussing.
  2. Monitor changing resolution.
  3. Monitor syncing with the video card.
  4. Monitor warming up.
Solution: Noise when turned on or off It is normal for standard computer CRT monitors to make a click, pop, crackle, hum, buzz, or other type of noises when they are first turned on or turned off.
Noise when monitor goes into standby mode When the monitor enters a "standby mode" or "power savings mode" this is similar to the monitor being turned off. It is completely normal for the monitor to make a noise when the monitor enters this mode.
Noise when opening Microsoft Windows or other operating system or when opening a game When a computer opens its operating system, for example, a computer opening Microsoft Windows or when a user runs a computer game it is very common that the monitor will need to switch its resolution of the operating system or game. When switching resolutions it is normal for the computer monitor to make some type of noise and/or for the computer monitor to flick or flash.
Noise during normal operation If the computer monitor click, pops, or flashes while it is being used this is not normal operation. It is very likely that the monitor may be failing or a component within the monitor has already failed and could also potentially be a fire hazard. We highly recommend that the monitor be repaired, replaced, and/or looked at by a qualified technician.
