Question about Samsung TXR3079 TV
Makes a high squealing sound when you turnit on. Makes the dog hold himself and wince in pain....me too.
samsung 30" slimfit makes a high pitched noise, but only sometimes. always goes away when turned off. the picture is still excellent, except for a very slight convergence issue (picture has a slight red tinge on left side of white lettering over black backround. very slight. the noise varies from high pitched ringing to a more static like oscillation. worked fine at apartment, started after moving. unit wasnt dropped or damaged
I have a very similar TV set, a Samsung TXS2782. I fixed the problem for now anyway. I sorta have a unknown way of solving problems with almost every electronic device I've encountered with technical issues, don't ask...a gift I suppose lol!
Anyway, I decided to detach the back encasing of the TV. It looked as though it would be simple, thinking I would only have to remove the screws surrounding the encasing and it would pop off. Well I knew that this wouldn't be that easy.
Step 1. Unplug TV set and remove all connected wires. Then remove the screws on the perimeter of the back encasement.
Step 2. Lay TV on its screen on a flat surface, preferably a soft surface that will not scratch the screen. ( this is so that when lifting the casing off the TV, the components inside will remain intact )
Step 3. Start lifting the casing off the unit, starting from the top of the screen. You will not be able to completely remove the casing, especially towards the bottom of your TV because I am not sure which model you have. But there will be enough space to insert a Pledge duster wand, or Swiffer 360 between the casing and the screen.
Step 4. Gently maneuver the duster around the internal components specifically towards the bottom right of the TV. there is a coil, numerous wires, and components most likely covered in dust. This is where you'll need a strong flashlight (I used a mini-mag lite) to look for all the layers of dust that needs cleaned.
Step 5. Brush off as much as you can see, but do not touch any circuit boards!!!! And avoid small wires because they can come loose. Mainly try to dust off the coil.
Step 6. I suggest using a compressed air can to spray as much as possible as well. This will help to remove a lot more dust and dirt that has accumulated inside your TV.
Step 7. Replace the encasing of the TV with the screws that you removed, being sure that you line up all of the connections with the cutouts on the back panel before screwing it back together.
Finally, plug your TV back in, power it up, and see if the sound is gone or at least more faint.
I hope this helps some of you out...I will continue to investigate a more easy and effective fix but this worked for me and a few others I've explained this to.

I was told that it might be a flyback transformer issue. Hope that helps, I'm still looking into getting mine fixed.
