Question about Optoma Office Equipment & Supplies
I recently bought a used Optoma PT105 and things meant to be white in a picture have a pink tint. In fact, there is a pink hue to the picture period. I know it is not concerning the cords- I've tried different HDMI cords and even when I'm only viewing the menu options and I'm not connected to my laptop, there is still pink tint to the letters on the screen.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

Hi kgomer782 I have similar issue. My optoma hd20 signal connection with a 3/6ft hdmi cable is perfect. However, no signal is detected when connected to a 35ft hdmi 1.4 cable. The 35ft cable is indeed working becuase I tested it succesfully when connected to a 1080p HDTV. Did you received any solution to your problem? I wonder if it has anything to do with the HD20 design of the "debossed" hdmi ports that prevents the cable plug from getting completely "seated" in the port? My 35ft cable has a flat square male ending however, the 3/6ft cables have slim male ending that seems to accomodate perfectly in the Optoma's hdmi port design...kaufmanekpr

SOURCE: Help! Our Optoma DLP
There is a lense behind the main focus lense that's causing this. Flakes of the colored tint are coming off causing white light to shine through. If you look at your projection, you can see black spots as well, these being the flakes that have re-located themselves. I dug into mine deep enough to diagnose this, to actually replace the little lense would be a little tricky. The unit has to be mostly disassembled. Also I haven't been able to locate a vendor who sells the part. Optoma wants you to send it in so they can do the repair, and won't part w/ these component level parts.
