My tv is around two years old. A few months ago it started making a high pitch noise. Sometimes you can turn the tv off and back on and the noise will stop but not always. A repair shop said it was most likey the flyback, and it might be repairable without replacing it, their labor rate was to much (200-300 hundred) plus with the amount of time we would spend without our tv, we would like to try to repair it our selves.
How do you repair a noisey flyback? Is there any way to get a diagram? My husband thinks he could repair it if he had instructions.
Seems like your television is doing the same thing as mine. I dont have a resolution but this may help from it clonking out completly. Leave it alone for now. My television started doing this months ago and I rarely even used it for the first two years due to deployment. One day it startd the high pitch, and i ignored it because i rarely turned it on besides when company came. About a month later it completly clunked out. Now i only get the green power light. NO pic, No volume or anything. Just that loud screech. Eventually it will go out, causing more problems. Usually you can go to a repair shop, get the piece name from them and then order and fix it yourself. The shop is going to do the same thing as you will, except charge you more for having ordereing it when you can do so yourself. Shops here charge about $60 bucks to let you know what it is... Shouldnt be a big change where you are.

Dec 30, 2008 - In my case, the monitor was fine for the first two months. But then started making a buzzing noise... 1) when on, 2) worse when .... my Samsung TV ismaking high pitched noises even if its turned off. I will NEVER EVER EVER ...
Get it to a tv dealer but my guess is its died. It may not be economical to repair but you may be pleasantly surprised and its a small job. LG are usually pretty good so I'm surprised its gone at this age.
A high pitch sound can be a capacitor losing power it would sound a bit like a fire work. most have back up on the board but it put more pressure on them the more times you use the tv. would check them and replace. all of them can be 5 in a row in some models.
Got the same problem with my second TX-S3082WH Slimfit...the first had the same problem...it was deemed unrepairable and I was advised to return it to Circuit City...now a year and five months later Samsung support has been less than helpful as I am 5 months out of warranty...don't know what I'm going to do...any advice would be appreciated
Its a real good chance that the HOT (horizontal output tranistor) transistor is shorted if so the flyback trasformer may be bad also. the transformer will make a tick tick sound if it is trying to start.
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.
