Holy smokes! The tech that Samsung sent about my high pitched whine just left. I told him, that from my observation, that it is probably the infamous color wheel whine. I figure that the sets have been around long enough that he has probably seen this problem before. But no, the guy just laughs at me. He tells me that there is no color wheel in the set! Oh my lord, I'm thinking this guy doesn't have a clue.
He tells me it's probably the digital board, which I upgraded back in Oct., or the lamp. I tell him again that it is more likely the color wheel because I only hear the noise when it spins up. He laughs again and tells me that there is NO color wheel in there!
I go into the other room and get on the computer. I go the TI DLP video that expains how the DMD, lamp and color wheel work together in the set to create the picture. I tell the guy to come in and sit down and watch it. He goes, oh I didn't know that. Arrrrrrrrrrrrggghhh!
I then show him this thread about others here having the same problem. He admits that Samsung has not trained him how to work on these sets at all.
I beg him if he's going to order a board and lamp, to please order a color wheel too. He says he will talk to Samsung and see what they suggest.
Now I am skeeerrrred. I pray that Samsung will tell him the right information. With my set just days away from being out of warranty, I don't need new problems.
Samsung, please, please give some training to your authorized techs. At least explain to them how they work!
