The tv usually turns on but all of a sudden it won't. When it does turn on it makes a loud noise like a boat. Someone told me its the fan but I'm not 100% sure though. The noise stays on until the tv

I would say that if there is a fan inside of it and it sounds like a fan bearing going bad then that is what it is. The reason for it not to be turning on anymore could be because whatever that fan is cooling has failed. Not sure.

Yes, the set uses a color wheel and the lamp faces it.

The wheel turns at over 8,000 rpm and is well known for this problem=bearings in the tiny motor go bad.

The high pitched or fan like noise (classic description) is this part.

Sooner or later the wheel (plastic colored segments) will shatter and set will shut down lamp and not operate---set monitors the speed of the wheel so if it slows down or stops it knows.

The part is readily available on the internet (Google the model number with "color wheel").

This can be a do it yourself repair and You Tube has video instructions for replacing the wheel by model number.

There are two common pitfalls to avoid which the instructions that come with the replacement part usually do not mention---if you decide to do this repair let me know and I will explain.

It could be 1 of 2 fans (fans are around $30.00 each) or more likely it is the color wheel beginning to fail. Color wheel will cost around $180.00-200.00, plus labor. I would recommend calling 1-800-samsung to find the nearest service center. Part should take an hour to an hour and a half to complete repair.

My tv just came on by itself and now just keeps going back and forth from off to on over and over

usually, it is background noise. Scratchy background noise. Gets worse the louder I turn up the volume. I ran a test on all the channels and it seemed to be the subwoofer channel. I've unpluged the subwoofer but that didn't help. I have also noticed that my receiver doesn't turn up nearly as loud as it used. I usually watch DVDs at a volume level of about 15 on my Denon and that's quite loud. But now, 15 isn't that loud at all. I went to Best Buy where I bought all of this equipment and they immediatly told me it was suge protector issue and wanted to sell me a high-end surge protector. Perhaps they are right but not sure why it began rather suddenly. Probably not helping you much.

It the colors wheel,the fan don't make that much loud of a noise.When the colors wheel spins off it axis it make very loud squizzing and buzzing noises.

Dust gets in these fans take the back off your set get some canned air and blow the fans out. Make sure you unplug the set first.

i have the same problem with mine. I took the back cover off at the bottom and the fan was going. get a scredriver and barely touch the center of the fan while it is on and if it stops making the noise then it is the fan motor. The bearings are getting ready to go out and it needs to be replaced.

The loud noise is the color wheel winding down when you turn the TV off. You need to replace the color wheel.

without a model number, i can't be much help. if this is a newer dlp or similar tv, the fan is probably going out. some newer tv's have a fan that is part of the light assembly, some have a separate fan.. the loud whirring noise is usually caused by bad bearings or the blades of the fan may have become unbalanced, either way, the fan making the noise will need replacing. the color going is usually caused by the lcd or dlp overheating and/or the lamp overheating.

if the tv is out of warranty, remove the back panel, locate the fan making the noise, and search for a replacement. if you have a model number, i can check around and see if i can find the part number for you.

hope this helps,
