I purchased a Samsung LCD tv, model # LN-T3253H, 9 months ago. Recently, a low buzzing sound is coming from the back of the tv whenever the TV has been on a long period of time and won't stop until the TV is shut off. I have disconnecting the cable box and dvd player to it but continued to make the noise. I also tried plugging it directly into the wall plug instead of the power strip - still no luck.
Do you have any suggestions on what could be the cause or a possible solution before I call for service? Thank you

It sounds like your LCD panel or your T-con board is bad . Panels are expensive so I would replace the T-con board first. You have to open the TV and get the part number from the actual board in order to find the correct one. You can find parts at www.interliquidparts.com
Call Samsung they may be willing to cover the repair since it so close the the end of the one year warranty. They are a good company and will usually work with the customer. Any brand of tv can fail and do at any time. Trust me on this. I've seen them do it before.
You should contact Samsung service to know if the internal setup for the picture sizing was not adjusted properly at the factory.
Take care that some of these sets have a user zoom mode. Maybe it is in the zoom mode. Check in your instruction manual before calling for service support.
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.
Samsungs will not switch to an input that has no signal going into it. Try putting the cables into the TV, then hit play, then switch to the correct camcorder input.
PEOPLE, YOU NEED TO GO BACK TO THE STORE, BUY THE SAME TV AGAIN, SWAP THE TV'S AT HOME AND RETURN THE "OLD" TV IN THE "NEW" BOX WITH THE NEW RECEIPT. IN THE CASE OF TOO MANY RETURNS, HAVE A FRIEND, MOM, DAD, SISTER, GIRLFRIEND TO BUY ONE FOR YOU AND DO THE SWAP LATER.
NOTE: I REALLY HATE DOING THIS TO THE STORES, BUT IF YOU PAY FOR SOMETHING IT SHOULD LAST LONGER THAN 30-40 DAYS. PROBLEM SOLVED! :)
