The color wheel sensor needs good cleaning. an optical lens cleaning liquid might help. also clean the fans and vents if you open it. I had to remove the sensor and clean. then it worked.

Hi!
Is the projector placed in a box or an area where it could generate overheating? Is this projector still within warranty?
Please feel free to update me. Cheers!

My bulb seems to go on overheat and the picture disappears when i did a remote check it said bulb life 73 percent why would this be happening


Well, I'm having the same issue and I just replaced my bulb. What the manual says is it is getting too hot (obviously). Make sure nothing is blocking your air vents both in and out on the projector. The manual suggests using a vacuum to **** out the dust but I imagine that wouldn't help much. Taking it apart might be a good idea to get a full clean out. If you've cleaned it and the vents are clean and it still clicks off for temp reasons there could be a fan malfunction. Replace it if it's not working. If it is working you can turn the fan speed up in your options and this should help. It is recommended in the manual if you're above 1500ft. The only other thing it could be is faulty electronics, and in that case I'm not sure what you could do. Goodluck! Fred

When i start a projector after few min screen becomes blank and projectors red led glows.Please provide the help.It is very argent.


well try this....

Before replacing your bulb, fan or any other component try first cleaning your optoma realy good!! HD70 doesnt comes with any kind of filter so you can imagine the amound of dust can be.
The most importent thing is to blow away any dust from your color wheel + the sensor attached to it .

for farther troubleshoting clean your fan's.
there are 2 fan's insinde the HD70.

probably the most problems will be solved by cleening the color wheel!!
if the problem is not solved ,chack the lemp and the fans if they work properlly.

For fan replacing:

It sounds like it is overheating. Are the fans all working? If so, try opening the casing and blowing all the dust out with a can of air from Staples/Office Depot. If the fans aren't working you may need to replace them.

Proector image is dim


I have changed the bulb on my LG projector recently. I found the rotating colour wheel to be full of dust. Upon opening the cavity where the light is redirected and reflected onto the imager, I saw all mirrors also had a layer of dust. I don't think it was so dirty that it affected the brightness of the image, but I cleaned it anyway using an earbud. I cleaned both sides of the color wheel as well. You need to be careful in working with the optics of the projector!
