One of the lcd panel filters has a bad spot on it. Most often its the blue filter.
The Yellow ATC Sensor detects a low TC (toner concentration).
Initial Action
- Check that Toner/Developer is present.
- Check the Yellow ATC Sensor for contamination. Ensure that the sensor is seated correctly.
NOTE:
To clear this fault, enter Component Control and set the value of NVM location 752-109 to 0.
This can be caused by many things. I've seen broken Drum contacts from improper drum installation causing Developer bead carryover. Toner dispense motor assy's failing. Developer Housing failure. DVHVPS failure.

I also have this on one of my 4 MT1060's. Did you find a solution? I am looking to do some self maintenance if possible.
I have the same problem with one of our mt1060s
The same problem has developed on one of our MT1060 projectors.
Also have the problem on a 1065
Ihave a Yellow almost "Heart shaped" cloud lately when watching anything. I looked into the Lens and could see a a colour box. within that box was a much smaller simular shape. I think it is probably a burn from the bulb, but not sure. I would to know if any one has a complete parts lists or an exploded view parts list of this projector. I think that colour box needs to be replaced.
