    i have a gateway 56" dlp tv and on my third bulb in 3 years but now making

    grinding whining noise.

    I have the same problem. The fan turns on right away and doesn't turn off until 2 minutes or so after I turn off the TV. Is there anyway to fix this myself? I can't believe it would be that hard to unplug a fan and plug in a new one. Thanks

The color wheel is the most common problem when it comes to noise from DLP's. To determine if it is a color wheel or fan: Turn on the set. When the noise starts, turn off the set. If the noise goes away within 5 seconds, then the color wheel is bad. If the noise goes away after one to one and a half minutes after the set was shut off, then one of the fans are making the noise.

    This was very helpfu! I thought it was the fan, but the noise went away in exactly 5 seconds, so it's the color wheel. Thank you very much!

Whining sound jd 4510 four wheel drive


accord to my books this tractor has a wet clutch transmission (12 speed) , first thing is to ck your fluid level in transmission , this is bit hard to reach on this one but is possible second obtain a small sample of fluid from transmission, have it tested , It can tell you alot , second you mention that hydraulic pump overloads engine with simple tasks like raise 3-point, this could be a stuck pressure relief valve due to yep you guessed it dirty filter (it bypassed itself) ck hyd fluid for proper level and clarity ohh and one more thing this tractor uses hyd pump for power steering (some others have 2nd pump for this) is it possible that noise is coming from that area , cus I have had to replace power steering valve on that model once for a loud Noise reason
remember if your gonna have a all hydro tractor save yourself a lot of grief and periodly wash shaft seals with water sure saves a lot of grief and leaks !!

How to fix loud whine from gigabyte ga-f2a55m motherboard


This particular main board doesn't have the video integrated into the mobo, so it's got a video card. Often the video card has a fan. The fan could be causing the noise. Have you tried briefly unplugging the processor fan to see if the noise stops?

Loud Whining Noise from Motherboard on Startup


Whining noise is something in motion or moving.Does the graphics card have a onboard fan?Is it clean and free moving.

How about the processor fan? clean,free from wires or anything hitting it.?

Disconnect hard drive and see if you get the sound.

4x4 whining noise


First, Check the transmission fluid level. Add more if it is low! If the noise continues, change your transmission fluid and assure that your transmission fluid level is correct. When changing transmission fluid you must drop the pan on the bottom of the transmission(You will know it immediately upon climing under transmission) it usually has10-15 small bolts holding it in. CHANGE THE TRANSMISSION FILTER WHEN CHANGING THE FLUID! If this doesn't quiet or fix the problem, then it sounds like your synchronizers or the bands in your transmission are worn(Thus the reason the whine goes away when it hits second gear) but check the cheaper of the two problems first. The synchronizers or bands are unfortunately a repair shop problem. I ran one of my vehicles for about 25,000 miles before having it serviced but I can't guarantee you the same amount of luck. Good Luck

Whining in the engine


I had the same whining noise, but after a minute or two it would go away. It turned out to be my water pump. It wouldnt turn first thing in the morning and the belt was just running through the pulley, (causing the whining noise). This may not be your problem, but it is easy to check. Just pop your hood and see if the fan is turning.

Fan Noise on Dell Dimension 8100


All computer fans have a general design.  The name in front of "fan" really refers to the designation.  You'll see case fan, processor fan, CPU fan, cooling fan, etc.  In the case of CPU/Processor fan, some are sold with heatsinks (the metal block sitting on top of your CPU).

The first thing you want to do is make sure the fan is clean.  Chances are dust buildup is causing the excess noise.

If that's not the case and you're looking to replace the fan, then you first need to find out the size of the fan. General sizes(diameter X width in mm) are listed on this page:

http://www.svc.com/case-fans.html

Generally, you're looking for something that will match the size of what you're replacing & push enough air at a reasonable noise level to cool the heatsink/CPU.  You want to stay in the area of 30dBA max for noise.  You also want to see if it has a 3-pin or 4-pin connection.

For example, if you have an 80mm fan, I would suggest something like this:

http://www.svc.com/saf-b82-19.html

It's pretty quiet with good airflow.  Also, it has a 3-pin connection, but includes an adapter for a 4-pin connection.
