Went to turn on tv and made high pitch noise like a jet engine. Made this noise a couple times and heard a fan kick on then power went off and red light came on.


Colorwheel eeds replacement most likley it could also be a fan but I would assume its the colorwheel especially if it was real highpitched sort of squealing sound. You can get the colorwheel and free tech assistance from the guys over at www.tvrepairworld.com

HL-R6768W not turning on. High pitch spin sound. Bad color wheel?


The high-pitched whine is definitely the color wheel.  The early color wheels had problems and many had to be replaced.  As part of the turn-on process, the TV checks for light and then checks for color wheel sync.  If the bearings are wearing out/dried out, it could cause issues with getting the proper color wheel sync, causing the set to not pass the turn on sequence.
Check Sears or partstore.com for a color wheel.  I like sears for experimental replacements since they allow easy returns.
BTW, mine is an early 61".  My color wheel was replaced when I had to replace my Light Engine.  My in-laws 50" was an early one and theirs went out within 2 years.
