Please help when i plug up the projector it display on top that its warming up and after about 3 trys its say the lamp didnt strike does that mean i have to replace the bulb or what? if so do someone where could get one cheap

The blinking green light means the unit is either Powering On (Warming Up) or Powering Off (Cooling Down).

Powering On the Projector
1. Remove the lens cap.
2. Securely connect the power cord and signal cable. When connected, the ON/STANDBY LED will turn Amber.
3. Turn on the lamp by pressing " " button either on the top of the projector or on the remote. The ON/STANDBY LED will now turn Green. The startup screen will display in approximately 10 seconds. The first time you use the projector, you can select your preferred language from quick menu after the startup screen displays.
4. Turn on and connect the source that you want to display on the screen (computer, notebook, video player, etc). The projector will detect the source automatically. If not, push menu button and go to "SETUP". Make sure that the "Source Lock" has been set to "Off". If you connect multiple sources at the same time, press the "SOURCE" button on the control panel or direct source keys on the remote control to switch between inputs.

If you are still unable to get the unit to turn on, try unplugging it for 10 minutes and plugging it back in. If it still ceases to work, contact Optoma here: http://www.optomausa.com/rma_policy.asp

Diagnostic...1, 2 or 3.
1- Ensure that the lamp door is present and closed.
2- Can you hear the safety switch open and close? (when you close the lamp door). If you hear it. its ok, if not, replace it.
3- Replace the lamp.

If you replace the lamp but do not reset the lamp hours then the projector will not ignite the lamp to stop it blowing up the lamp and causing further problems. You can reset the hours without the image, on the x2 version you turned on for 1 minute then held down the volume up and down buttons for 10 seconds but all versions vary. The infocus website can usually tell you how though you may have to look for it a bit. Failing that try a firmware update available from the infocus website that should erase its brain so you can start again, hopefully you have kept the original leads it was shipped with to do this otherwise it will cost you another £20

the ballast is not striking the lamp. replace the ballast.

need a ballast

lamp is not striking after 5 tries. try new lamp. if it still doesn'r work, you need to have the ballast replaced.

Also having this problem."Warming up" then "lamp didn't strike" then "retrying" stuck in a loop. It's at a school where I work and nobody has reported any messages regarding the lamp hours.

if mains is ok and fan running ok, could be a bulb service issue, all lcd projectors have an internal lamp life counter which counts down and once the lamp has reached the end of its life it will not fire up and a new bulb will be required.

Hi there

You should reset the lamp timer as this LCD Projector's counter counts down the hours and will not fire up if this has not been done.

If you have reset the lamp timer and the problem stil occurs , you'll have to replace the Ballastboard ( lamp's powersupply )

I believe that does mean the lamp is dead. If your model is the LP600, you need the SP-LAMP-019. A quick search on eBay found one for $320 new. From the InFocus website it is $499 so that is not a bad deal. InFocus offers a 6 month warranty, so that is something you will want to keep in mind.
