New Samsung Tv High pitched hum

There is a specific reference to this condition on the Samsung support website. My new LN-T3253H had the same whistling problem when I first started using it. Several days into use the whistle has subsided somewhat. I entered a tech support case on the Samsung support site and Samsung is sending a technician to my home to perform a repair - no charge as unit is still under full manufacturer's warranty.

The best answer is to return the set to the store and get a different brand. This set was made with this problem. If you complain to Samsung customer support they should get you a defferent tv or a new power supply board for this set.

Don't know if people are still having this issue or not but figured I'd post what i went through to help anyone that has. My LN-T3253H tv as out of warranty when I finally got around to calling Samsung. They flat out lied about the commonality of this problem and I convinced them to at least pay for any parts. Problem is the labor of a technician would be around $150. So, I bought the new power supply from Partstore.com for around $70. Just go to partstore.com and enter your model number and look for the power supply on the page. It took 3 days to get the part. It was very easy to replace. All you have to do take off the back cover of the tv (think there were around 12 screws all around the outside and one where the A/V connections are and pull off. Unhook the plugs going to the power supply and the four screws holding the board and then replace with the new board. So far, this fixed the issue. Keep your old board in case it starts happening again. You can probably have the old board repaired to fix the original problem since so many TV repair shops are aware of the issue. I am trying to find out from someone which specific capacitor or other piece is causing the issue and plan on fixing it myself. If and when I do, I will also post that.

Make sure you give Samsung a ton of grief when you speak to them and see if they lie to you also. I had just bought two of the new Samsung LED TV's for my media room. They work great but I returned both because of Samsung's refusal to fix my LN-T3253H and I will never, ever buy Samsung products again.

It's the power supply unit....a transformer needs to be soldered. Read this link for more onfo....
