This is usually caused by a leaky or noisy diode.
take set apart and make a funnel from a piece of paper, and try to pin point your sound. then try to carefully more or bend the part a lil till the problem goes away, if you cant get it to stop. then you will need to replace the part.

I have a magnavox 37mf331d/37 that has developed a high pitched whine.the longer the tv is on the louder the whine.the tv is 5-6 yrs old

It's likely a capacitor associated with the power supply having gone bad.
It's obviously beyond your expertise to repair it yourself.
Find a trustworthy repair shop and take it there.

High pitch whine when tv started then it lowers in pitch

That could be either the color wheel or one of the fans. try listening to which area of the set its coming from.

The picture is taking longer and longer to come on. It's not a consistent length, last night had it on several hours, it was off for an hour and a half, turned it back on and it took over 90 seconds for...

if you can get another one for a reasonable i would certainly consider that. the cost to get these lcd's fixed sometimes is not worth it. you seem to have more than one problem with the set.

High pitched whine/sometimes TV won't turn on

The power supply on this model will whine when it is shorted or overloaded - the set would have to be brought in to determine exact cause.

Same problem: a high pitch whine after extended driving

Sounds like a dry/failing bearing or power steering pump noise. You first need to try to track down where the noise is originating, and the most likely place is at the front of the engine.
I would start by listening with the hood up while parked with the engine running and the noise present, and seeing if it is coming from there. If so, the most likely cause is something connected to the belt - e.g. AC compressor clutch, tensioner, power steering pump, or generator. Can also be caused by the belt just slipping (warn out belt, tensioner not working properly).

Loud engine whine (like a jet noise) from 2002 subaru forester

Have you crawled under the vehicle and personally inspected your exhaust line from manifold to tail pipe? The roaring sound usually occur when there is a hole in the exhaust line. I had it happen to my forester before. A hole half the size of a dime made my subaru sound like my old 74 chevy pickup.

High pitched whine when the motor starts

Had the same problem. It quit within about 5 seconds after turning the TV off. Replaced the color wheel and the whine is gone. The picture also looks brighter, which may be due to dusting the projection lens with lens-cleaning compressed air (from a can). The color wheel was about $100 from Samsung parts and it took less than 3 hours to replace. See http://www.jangro.com/a/2006/07/24/samsung-dlp-replace-color-wheel/ for good info, and be sure to read the cautions.

Occasional 'whistling/whining' from back of TV

I wonder if there is enough air circulating around your equipment?? My DVD recorder makes a sound unless I open the doors on the cabinet that contains all of my equipment. The cable company says it is a fan to cool down the units.
