Optoma projector We are having problems with our projector. The screen (or light bulb) flickers. We have had it just a little over a year and first the colors got funky so we replaced the bulb. Now when we try to watch it(we use ours as a television), the screen flickers. Not quite sure what all to try. We have tried the resync button and that does not fix it. Any suggestions would be great!! I have a optoma ep716. All i get is an display of white on the left black on the right. Any ideas? Perhaps the colour wheel? And how do I open the thing to even try any repairs? I feel like I'm going to crack the casing trying to get inside.

are you managing to get into the menu at all and reset filter and lamp hours?

By the way - although optoma what cheap option for our school, i now get hitachi with 3 year bulb warrenty.... mine BURNT out luckily not at weekend or school may have gone up too - expensive optoma really then if that had happened.
good luck

Try putting the bulb into normal (rather than eco) setting.
Check the bulb is seated correctly.
If this does not help you may have to contact your bulb supplier to see if they can swap bulb for you.

Colourwheel, when it losing its speed. Fault would lock like flash of the coulors, wrong colours or no colour at all.

I think it's a lamp driver issue from what I've seen others have gone through. I also read that if you go through the sequence of unplugging, plug back in, wait 20 seconds and try to turn on, multiple times, it will finally kick on and work. I just got mine to turn back on by doing this and waiting through the fan cycling without the light turning on. After the 4th sequence the light flickered. After the 7th sequence it finally turned on and is working. Now I can watch the Super Bowl and will look into replacing soon.

i had, have the same problem i also replaced the bulb then shortly after the power went out no standby light or anything. From what i've read so far it seems like a power supply issue so i ordered two power supplys from optoma 1 for lamp 1 for the unit waiting on delivery from CA they were $ 99 each if this work i'll be one happy camper. Three years no problems it's a great machine with incredible picture using 106" screen

either the lamp has/is going to expire, or the ballast is bad. if the lamp has bulges or black spots on the inside, replace the lamp and clean out your projector with canned air. too much dust keeps in the heat and makes a 2000 hour lamp go in 1100 hours.

Hi, I had a similar problem - the screen flicked through blue, green and red sometimes with a slight ticking noise. The problem seems to be that the colour-wheel is getting stuck - the first time this happened I sent it back to optoma who gave it a clean - it has happened again since thouegh and I just took the case off (you'll be able to see the colour wheel under a black plastic flap - remove the flap) I then used a cotton bud (q-tip) and turned the colour wheel whilst lightly pressing the cotton bud against the wheel - I also gave everything a blast with a can of air. My HD72i is ceiling mounted - optoma suggested putting the hoover pipe across the vents every now and then to keep the dust down. Essentially it's dust that is stopping the movement of the colour wheel.

Hope this helps.

Use the warranty! since you anly had it for 8 weeks, and the waaranty last for one year, go back with it and get it repaired or get a new bulb. A buld last at least 2500 hours, in eco mode it last for over 3000 hours.

Good luck to you

Hi SmartMex

This in not a lamp problem , but rather a Mainboard issue.

You will have to take it to a Service Centre to either be repaired or replaced.

DONT THROW AWAY YOUR BULB JUST YET!!! IT MAY BE THE COLOR WHEEL!

I have an optoma hd70 and was having the same problems. I also tried the "dust blob" tutorial, but unfortunately it did not work for me (and I ended up getting dust on the lens I couldn't get off myself). I started searching on the net for more answers and found some information regarding the angling of the projector. Apparently, if you tilt the projector with the back raised too high, the ventilation system does not work properly and this increased amount of heat damages the color wheel inside (this causes the wheel not to spin correctly and display a flickering effect...and that's also why it works for a few minutes on start-up but then gets too hot and the wheel skips and creates the flicker).

Luckily, I have a very extended warranty and was fortunate enough to send it in and have the dust removed & color wheel repaired/replaced. Now, I've lowered the stand for the projector to not have it tilting at such a high angle and haven't had any problems yet...but it does take awhile to get effected (had mine for about 1 & 1/2 years)

I know I should have probably just sent it for repairs in the first place...but who wants to miss out on having a projector for two weeks when a tutorial says I could've fixed it in like 20 miutes?!?! Oh well. Hope this helps someone...good luck;)
