Our Acer ph530 projector (which has a brand new bulb) will work for maybe about an hour and then the colors start flickering. It never goes black but the colors kind of invert themselves. I hope I am explaining this correctly. We have a fan that blows on it to help prevent it from getting too hot. What to do to fix this from happening? I will appreciate any help

the image is flicker, the light is twinkling, after seconds or minutes ,the projector power off.
1,the color starts to go out, it become the white and black,the image color is disappear.
2,then,the projector running off after only a few minutes,
it is a general issue:the inductor need to be cleaned
Use a cotton swab moistened with alcohol to clean the inductor.
the inductor (Sensing element),is near to the Color Wheel.
the industor : is a black little element,as little as 3 sesame seeds

yes, it's still black n white

Mine does the same. When it was still under warranty I kept sending it in to get it fixed, but Acer never fixed the problem (rather they caused more problems). I sent it in for repairs 4 or 5 times, but eventually the warranty expired (after they told me they would extend it from the dates of the repairs). I haven't found a solution. If you do please let me know. Anyway, I don't recommend this projector to anyone else. AND, I certainly don't recommend Acer's customer service. Their warranty is worthless.

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.

the color wheel is dirty. It just need to be cleaned.

I have the same problem as philvo. I was watching, the projector was operating normally, I heard a snap, there was a flash of light behind me I believe, and my Mitsubishi XD300U projector went to a black and white picture. That is all it will show now. All lights show normal operation. I would like to know if it is worth getting repaired. Does anyone have any ideas?

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;)
