Take front panel off, take cover off lower section. Find hi volt problem by locating Hi volt trippler block. On block there are 4 wires that co in to the trippler. The one wire that has a red plastic insert holder going into the block should be taken out and let dangle. Do not let get near any metal to arc. This is the HI VOLT lead from the flyback transformer. Turn set on if piolet light comes on and you have good HIVOLTAGE probley the block is bad . This can give you the noise you hear

My samsung HL-S5086W has a high pitched buzz that is present when muted, and continues for 2 or 3 seconds after you power off. Any ideas? I heard if it continues after power is off, then it is a fan, not...


Samsung BP96-01579A Color Wheelno the fans will not produce a high pitched noise. they will ususally produce a dull noise because they dont spin anywhere near as fast as the color wheel. the color wheel will start up before you see video and stay on for few moments after power down. if the fans were faulty the tv would give you message on screen.

The high pitch noise is the color wheel that needs replace the noise is coming from a bad bushing that goes to the color wheel and is a common problem.

Screen suddenly turned off, makes an odd high pitched noise when it tries to turn back on. power button flashes orange


Sounds like there is a power problem if the neutral (return) wire on the power supply has become high impedance (or even disconnected) then you will get a high pitched sound coming from the TV PSU also the voltage that is presented will not be 240V which will give you the same problem.

The orange power button means standby if you fix the PSU then the TV might work again but it may have been damaged by the PSU.

Hi, I have a Magnavox 17MD255V/17 combo dvd-tv. Everything works fine except that the AC adaptor has a high-pitched whistle that continues while the tv is on. I tried unplugging from the the tv itself and...


TAKE THE AC ADAPTER APART. LOOK AT WHERE THE MANUFACTURER PUT HIS GLUE AND REDO IT CLEAR NIAL POLISH WORKS BETTER IT FLOWS UNDER THE PARTS BETTER. YOU CAN PLUG IT ALL IN WHEN ITS APART BUT MAKE SURE NOTHING CAN SHORT OUT. THIS WAY YOU CAN PINPOINT WHERE THE NOISE IS COMING FROM. OTHERWISE GLUE THE TRANSFORMER AND ANY SMALL FERRITE BEADS THESE SWITCHED MODE POWER SUPPLIES OPERATE AT HIGH FREQUENCIES AND LOOS PARTS CAN VIBRATE CAUSING THIS NOISE.

High pitched whine/sometimes TV won't turn on


The power supply on this model will whine when it is shorted or overloaded - the set would have to be brought in to determine exact cause.

Samsung LNT3253H is making a high-pitched noise


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.

High pitched noise


There is a singing coil in the power supply. This set uses whats called a Switch Mode Power Supply(SMPS) and as the picture changes, so does the amount of current the TV draws. Thats why the sound changes with the picture. This could be an indication that a part is going to fail soon or it is just a loose coil winding or a transformer winding. You should have the set checked out by a pro to be sure. Good Luck
