Optoma EzPro 610H Multimedia Projector Display is all white
Your projector is LCD based. That is, basically, a tiny panel is a computer monitor with a lamp behind it to shine through the panel and lense, onto the screen. This all white screen means the pixels of the LCD are all "deactivated" allowing all the white light through. This happens on computer monitors from time to time. I cannot find a blind reset, meaning there's isn't a method of holding down a series of buttons to "reset" the projector.
aside from calling support, as their manual is useless, I would recommend powering the unit off and then unplugging all cables, including power.
Press and and hold the power buttons for 20 to 30 seconds to see if it clears up your issue. Sometimes, after unplugging the unit and pressing the power button on the projector will briefly light the panel lights and then they fade. This may be enough to drain enough power to force the projector to reset to normal conditions.
If if that doesn't work, I'd recommend leaving it unplugged for a day or so and try it again. Beyond that, the controller board for the display may have failed. It shouldn't be the case, but it is possible.
However, I feel the unit needs a simple reset, which normally you'd do though the menses, which obviously possible.
