Question about Optoma EzPro 610H Multimedia Projector
I had a computer hooked up through s-video. I fell asleep on the couch and left the projector on all night. The computer was shut down. When I woke up 6 hours later, the projector was still running (not timed out) and the display is all white. I have tried going into both the video and s-video ports with the same result. I get audio but the video is all white. I noticed also the normally on startup it shows a blue screen that counts down lamp warmup or something. It isn't doing that and it won't bring up the menu options either. When I look through the fan holes I see that the blue, green and red are all on. I'm assuming that is what is making the white. HELP! (please)
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.

its definitly a cooling issue.the temp sensor is working because it shuts the unit down.when a lamp goes it goes just like a light bulb.you can open up the unit and locate the fan take it out and go to a radio shack a match it up to a universal fan.

Hi, I have an Optoma EzPro 751 that had a similar problem, although it got progressively worse until it only took about 5 minutes to begin acting up. I was really frustrated, as the bulb only had around 600hrs at that point and the picture was bright. After some searching of forums like this, I found someone else with the same exact problem, but with a Dell projector (made by Optoma).
The culprit was LOTS of dust, built up on the circuitry, built up on the optics, built up everywhere! Solution: carefully open up the case and use canned air or an air compressor with a blow nozzle attachment. (warning-compressor air MUST be filtered first as it otherwise contains moisture and other harmful suspended contaminants)
I was at the end of my rope, and this really worked for my problem. It's worth a try, but BE CAREFUL! There are delicate parts in there you don't want to blast apart with air. If you use the cans, buy several as it took me quite a bit of blowing with a compressor regulated at 90psi to get it all out. Good luck!

SOURCE: EZPRO 610H...has a red shadow
this is ghosting, caused by interferance. cheaper cables tend not to have metal sheathing and those ferrite RF suppression thingees on the ends, which prevents this problem.
also, avoid running your signal cables next to power cables. If your cables are long (say more than 10m) this may also cause problems.

Hi, I'm not sure if it's the same problem I had..
I had it on picture mute, for maybe 15 mins, which may not have been a good idea. While it was muted, it made a sparking sound, and then a very loud grinding noise. When turned off, the lound noise stops, and the fan continues as usual for about a minute. As soon as it's turned back on, the grinding noise is back. But the logo seemed to display ok.
I took it in for repairs, and they said they needed to replace the color wheel to fix the problem.

SOURCE: color problems
i don't know if this will work but..... I have an Optoma h27 and we were having problems with the color and ours is mounted on the ceiling in inverted also; and after two years we started having color problems, come to find out that on the menu there is a option for high altitude and that had been turned to the "off" position (probably by our kids resetting all the options and not turning this one back on)..... after taking it to a tech that cleaned it for $97.00 and said there was no problems he could find, we played around with the remote/menu and came across this high altitude option and when we saw it was on the "off" position, we put it to the "on" position and another fan inside the projector came on and that helps to keep the inside of the projector cool at all time and helps from the color becoming weird..... Try this on yours and hopefully that will solve your problem.
