Optoma H30 -- When turning on projector the green light on power button blinks and the projector sounds like it is going through a cycle....after the cycle the lamp light comes on and nothing comes on the screen. I thought it may be a blown lamp so I replaced and have the same problem. Can you help?

If you only have 300 hours on it it should still be under warranty. Before doing something to void that I would check with Optoma techs.

if all lamp are red, and no light on, It is power supply issue,
you need to replace power supply, it will be ok.

you can send me your old power supply photos, perhaps i have same parts,

Reset the lamp timer and you should be fine.

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

hi,
Do one one thing. check the lamp of your projector. For removing the lamp see the bellow picture.
also check the lamp colling fan. If it is faulty this fault can occur.



1. Use a screwdriver to remove the screw from the cover.(1)
2.Push up and remove the cover.(2)
3. Remove the 2 screws from the lamp module.(3)
4.Pull out the lamp module. (4)
ok

if the fans come on and the lamp doesn't, it's the ballast or the colorwheel. if no fans either, it's the power supply. also, did you reset the lamp timer?

Hi

Try to change the cable from source to your projector. or make sure everything is connected properly.

Hope this help

Hi!

Here is a link to the "Troubleshooting" part of the manual to Optoma H56 Projector. Hope it will help!

OK, found the solution on the net, you have to use the buttons on the projector instead of the remote to access the menu item.

The only thing I can think would be that the projector is heating up because the air filters are clogged.
