My Dyson AM01 is making a whining noise. How can fix it? (Calling Dyson's tech support only resulted in a small discount towards spending $300+ on a new fan!) Whines upon starting and will continue for...


Hi Tom,

I'm sorry you're having difficulty.

It is a very difficult thing to try and diagnose something like this without an inspection of some kind and I wouldn't want to speculate on the cause of the noise.

The only option is to speak to Dyson directly again. Please give the Dyson Helpline a call on 1-866-693-9766 (US), 1-877-397-6622 (CA), 0800 298 0298 (UK). Our experts will be happy to talk you through some further diagnostic checks when you have your machine easily to hand.

Best wishes,

Allan

When turned off the tv makes a whining sound (not the expected whining noise) and then sounds like a wheel (like on Wheel of Fortune) slowly winding down. Yesterday it didn't come on (sound, no picture) so...


The whining if it sounds like a mosquito type whine! it can be a capacitor, i have same issue, you can usually hear when u are on standby but if your hearing like a "wheel of fortune"! and slowing down would likely indicate it's a fan which is possibly covered in dust and the whining is the fan stopped trying to power forward or it slowly moving and slowing down. If you think it's the fan you should unplug your TV to avoid the fan burning out then have someone who knows what their doing take a look at than fan for you and clean the dust away from it, you may be able to get some access through vents in the side and can try your vacuum cleaner in those vents while TV is unplugged but i'd not go messing inside a TV without wearing some rubber gloves!
Looks like the engineer would need to remove TV casing, check fan to see if it is blocked with dust or not, or if just failing for other reason then either clean or replace. If you don't get it done and the fan fails to cool the TV your risking other vital components overheating and breaking for good so best get it looked at, sounds like the fan to me...

My RCA DLP seems to have a frozen screen.


Do some research as this model is also prone to the color wheel going bad---the high pitched whine or even fan like sound points to it.

I have a rca hd tv 42 inch model #40LA45RQ stays on for about 15min to half hour goes off please help


hi,
Check the lamp cooling fan. If the fan is faulty then the lamp will become overheated and the protection circuit will turn it off . you can see the fan near the lamp housing.
ok

A noise had been gradually increasing from a grinding sound to a high-pitched whine. COntinues until the screen is completely off. Sounds like a fan motor may be out of lubrication.


THAT TV HAS WHAT IS CALLED A COLOR WHEEL WHICH SPINS AT VERY HIGH RPMS AND CAN MAKE HIGH PITCHED WHINING/GRINDING NOISES IF A FAN WAS BAD THE TV WOULD SHUTDOWN AND THE SOUND WOULD BE MORE DULL SOUNDING.

WHINING SOUND


More likely it is the color wheel this set uses---it is located inside the optical engine---part number for it:

267888This part is no longer available from RCA but is available on several sites on the internet (google the part number)

The wheel will when going bad sometimes make a fan like noise or even a high pitched whine.

Check out the sites on the net that sell this for price and decide if you want to attempt to replace it or if you have to have a shop do it for you.

Let me know if you have any questions or need advice.

REGARDS, SD TECH

Two possibiltes. A bad cooling fan or what is known as a color wheel. is this a whining sound. does the colors flicker. a bad fan could have contribited to the bulb going out too. to identify a technician would have to take back of and examine fans and listen

Buzzing sound by bulb


be quite sure that it is not the fan physically touching the case; other than that, scope your B+ voltage to the ballast and be certain it is clean;  while it could be that or the lamp itself, it is most probably loose or misaligned case assembley
