HLt6187sx/xaa dlp chip and fan no. 3 problem

http://simpletonpattern.blogspot.com/2009/09/how-i-fixed-my-dlp-tv.html .this link worked awesom for replacing the dlp chip. the chip cost me 160 dollars. fan no. 3 was inside the back of the tv on the right side behind the bigger fan and is the same part number as fan number 1. i cleaned the dust off my fans with a q-tip and the notice stopped showing up on the tv. both were very simple fix and a caveman could do it
