Less than 180 Hours on this projector. Picture is fine on all sources, yet it flickers.
With the top cover up and all internals exposed, I can distinctly hear a low mumbling chirping from the color wheel motor. The picture is wonderful, but every time the wheel chirps (every few seconds) there is a few bright white scan lines appearing in the picture for a split second.
Does anyone have a service guide for this projector? Has anyone experienced the same problem and had it resolved? My instinct tells me either the color wheel motor is bad or a varying current supply to it. I need the service guide to troubleshoot.

I think it is the time to remove the cover and check for air filters blocked with dust.
When this happens, air doesn't flow freely through the projector and result in overheating, which leads to automatic shutdown.
Have you tried another lamp? Sometimes thats your problem, but I've seen a several occasions that the a defective power supply causes this symptom. Do you see an image flicker before the projector shutsdown? I do have some spare parts for this projector.
I'm on Ebay - gtitubro if you want to contact me through there.
it's chirping because it's trying to keep in sync with the dmd chip. for the refresh rate, go into the menu and first reset the settings to factory default. if this doesn't clear it up, try matching the signal.
try resetting the settings to factory default through the menu. if there's still a problem, take the cover off. if you look from the back of the machine, inside on the bottom left, you'll see the main board attached by a large white plug. use something thin and non-metalic to push the bottom of the board towards the plug to tighten it. now do the same to the other side of the plug. this should solve it. if it doesn't, you need to replace the main board.
Many laptop computers do not automatically turn on their external video port when a projector is connected. On many laptops, the activation function key is labeled with an icon or the text CRT/LCD.
Try the Function Key with the Icon of a monitor to enable the external video port.
If that does work, look at the settings on the projector using the buttons on the top.
Check the "Default Source"
Default Source toggles among Computer 1 analog, Computer 1 digital, Computer 2, and Video. This determines which source the projector checks first for active video during power-up. Highlight Default Source and click the left or right mouse button to toggle among the options.
