I'm sorry, I goofed. I meant "color wheel" motor, not fan. Ugh. I can't believe I didn't catch that in the preview post.
If it was the fan, it wouldn't require the mainboard replacement.
If the fan for the lamp was bad, the set would likely hit a temperature threshold and turn off.
If the fan for the circulation was bad, same thing. The unit would turn off.
The color wheel itself may not be spinning in sync, causing that picture artifacting.
So I apologize. It's not a fan motor, it's a color wheel motor.
So before you order those fans, please consider taking that $75.00 option off the table.... and you're left with:
<i>I don’t mind tearing into the HLP5663W because I’ve worked as a computer tech for some time (and I don’t have a warranty to void). However, I don’t want to throw good money after bad.
I don’t think it’s an option to have service tech replace the mainboard ‘cuz that must go $1,000 when you add the labor. For just a few $$ more, I can get a brand new LCD. </i>
That's probably the aspect you should look at it from.
If it was the fans, it wouldn't require the mainboard replacement, where I said "Both remedies appear that a mainboard replacement is necessary".
(Where did that post go? Did it disappear? I know if I was quoted, it had to be here somewhere!)
So let me rephrase that for your consideration:
If it's either the color wheel motor, or the processor, then it's likely that the entire board needs to be replaced. The tough part with DLP is that almost everything is on the engine (the main board) - and while it's a convenient repair (one board fixes all), it's not perceived as the most cost effective way from the consumer point of view - and maybe rightfully so. The intricate nature of the board itself requires an incredible amount of accuracy, so that's why we do all the adjustments at the factory on those boards so it's ready out of the box, since it can't be done in the field.
Anyway, I wanted to clarify that, and apologize for the typo oopsie.
