Loud buzzing noise when turning on

I would start by checking all the cooling fans to see if one is dirty or possibly failing.

does it allow much water into the tub? u may beed to check ur water inlet valve for OHMS and for proper voltage at the coils, they may have went bad

Sounds like you've got a thread jam going on in the bobbin case area. Good cleaning and a new needle will probably fix it. See: https://answers.yahoo.com/question/index?qid=20091202121550AAHxN8y

See attached photo: you have a bad color wheel----it turns at about 12,000 rpm and bearings in the tiny motor go bad.

High pitched or fan like sound is classic symptom.

The wheel is available on the internet and You Tube has video instructions by model number for replacing it---Google the model number for the part number for your set to locate the part and instructions.

This for most people is a do it yourself job---takes like 45 minutes start to finish.

If color wheel slows too much set will shut down as its speed is monitored and the wheel can even shatter causing shutdown of the set.

This tv have a colors wheel. The tv colors wheel is dead.The buzzing noise is the cause of the colors wheel is spinning of is axis and rubbing sides of the motor.Hire a tv tech. for the job.Colors wheel is hard to replaced,because have to take out many other machanical parts,even before can change the colors wheel it self.

I would need to hear this noise to help, sorry, but you need a shop to look into this.

buzzing noise is cause by small electrical arc inside the unit or a problem in your audio circuit.if you can open the unit up and check if its an electrical arc.

try replacing av cords..if not replace tv

If it is a buzzing noise, it is the Ballast for the lamp.
If it is more of a grinding sound, it is the Color Wheel motor.
Does it go away when you turn off the tv? If so, does it stop abruptly or does the sound tend to get softer (winding down noise)
If the noise stops abruptly it is probably the Ballast.
If the noise takes several seconds and seems to get softer until it stops about 30 sec later then it is the color wheel motor.

Got the same problem with my second TX-S3082WH Slimfit...the first had the same problem...it was deemed unrepairable and I was advised to return it to Circuit City...now a year and five months later Samsung support has been less than helpful as I am 5 months out of warranty...don't know what I'm going to do...any advice would be appreciated
