Samsung LNT3253H is making a high-pitched noise

My Samsung LNT3253H is making a high-pitched noise after it's been on for a while. The TV is only a month old. I have it in an entertainment center and am wondering if it is getting too hot, causing the high-pitched noise. Is that the possible cause? Any others? Thanks.

I had the same issue. The tech that came out today removed the transformer on the power supply board, "resealed" it, and replaced it (re-soldered the same part back on) -- the transformer apparently vibrates because it was not properly sealed. BTW, mine was about the fifteenth that he has performed this repair on within the past couple of months -- all 32" and 26" Samsungs. Now, it appears to be absolutely silent.

The high-pitched noise you are hearing is the color wheel. It is a very common problem in Samsungs.

I have Samsung DLP TV 50 inch HL-P5063W


First thing to look at is the color wheel this model uses--usually it will make a high pitched fan like sound but can make a grinding sound also.

If it slows down from the 12,000 or so RPM speed it will cause color issues.

Samsung SlimFit 30" high pitch whining noise


I have had the same high pitch tone problem for several months after about 20 minutes of use. It is so bad it's rendered the TV almost unwatchable. I contacted a repair place from Samsung's website. I was told that is likely the flyback transformer. I don't know what it is, but it sounds cool like a flux capacitator. I was told it would be about $100 to fix. However, I have had very little luck getting the repair shop to order the part and do the work.

High pitch noise


Hello there, You have to specify where the noise is coming from. Is it coming from the speaker or from the back of the unit. SMPS power supply powering your unit create this kind of noise when some capacitor gone out of their value.

Good Luck.
