Hi Stacy: Vary glad to know JVC do care after you sale your product. I had this JVC HD-61Z575 for a year. From day one I had this Hamming noise. It just getting untolarable now. So I open it up and find out it is this cheap cooling fan for the lamp cooling(Nidec BETA V, TA300DC). I discounnect it, the noise go right away. The other 2 fan sound acceptable. I hope it is OK after I close it up. Then I seached for the replacement parts for it. But All I get is 2 wire type. Do you have a replacement parts? Or best of all have your engineer have find a better replacement parts for it? Or at least you can tell me what is the third wire for. Do you have a electric diegram for the fan? By the way I,m a enginner and have designed all type of system. This shoud be a easy problem if you can help me on the info. Merry Chrismas anfd Happy New Year. Ping
