everyone, 3 months later, after much time to research the problem on my
projector, I finally managed to solve it and everything works
perfectly. Here's what I do:
-One day, I turn on my projector and it was a funny noise (buzzing
noise). I turned off and then I turned back. More picture and sound was
still in office.
"I sought what could be the source of the problem. I thought a
moment that it could be the color wheel. My son is hitting your site.
After long trying on solution that you give, no results!
"I open the projector to clean it (with great difficulty) and then
I clean. Remember that in the instruction manual, it is clarified to
remove the lamp and clean the air filters for better ventilation of the
lamp after 250 hours of use!
"I closed everything and projector Do not! So I thought it was the
lamp that was broken. I buy a new lamp and after installation, the
projector is still running NOT DO!
- I looked for a new projector .... 3 months later my son was
tired of not having big screen so he returned to this site and reread
and reread all the tricks. It is dropped on it: KEEP YOUR FINGER FOR 15
SECONDS ON THE BUTTON CHANNEL! I quickly realized that it
was''buttons''KEYSTONE He turned on the projector, press both buttons
magic and then ... LAMP lit!!
"I dropped the search for a new projector!
This projector has given us many problems but it works well. I will give you news and also because I am very curious!

Make sure the venting for the cooling fan is clear and that it is activating. The only time I have seen this in a projector is when it overheats. If it reaches a certain temperature and doesn't sense the cooling fan being on it shuts down to protect the bulb and protect against fire hazard.
did you turn it off or unplug it? not to sound too obvious, but make sure it's still plugged in properly and the switch is on. if the led is lit on the top, it's getting power, so it's not the fuse. if not, the fuse is located on the power supply board inside the projector. if the led is lit and the fans don't turn on, it still may be a power supply problem. if the fans go on and not the lamp, could be the lamp, ballast, or main board. if you need to send it in for repair, try av solutions in ny. they're really good. www.avsolutionsny.com
I think it's the bulb, the best would be to take it to the shop where you bought it - or any other good electronic goods shop - so they can test it. If its still under guarantee its better to take it to the dealer. Mine had to have the bulb replaced after only 8 months, but it was still under guarantee.
I had the same problem after purchasing a new bulb. My husband pulled it out after it would not fire up and the new bulb plug in conecter (white with 4 holes with two wires) was different. Take your old bulb and compair the two conecters and see if they match, then check if the wires are in the same slots as in first and last. Mine on the new one were in the first and second to last slot. So we took the wire out of the second to last and put it in the last slot and installed it and it fixed the problem. We also had to unplug and replug it in and do a master reset by pressing the Power and Channel buttons and the same time for 15sec. Hope this helps.
the fans in these models do not have a speed sensor wire to let the main board know to turn off the lamp to not risk overheating. so if the fan goes, the lamp remains on. however, if the lamp exploded, check the vents for dust. there is a temp sensor that will shut down the projector if it gets too hot. if the vents are clogged, blow the dust out of the projector with canned air. the dust keeps in the heat that the projector is trying to expell. easiest way to repair the fan w/o buying a part: splice the fan wires together. they can share voltage. if the 80mm fan does not work at all after that, replace the fan (pn: 526-0192-xx).
Make sure that nothing is obstructing the fan. Try to rotate the fan with your fingers to make sure it is free. If it is, you would be lucky if the fan is at fault because this is rather cheap and easy to find if not it is the main board which is at fault.
