Green green is power on, normal
then it tries to light the lamp, but it can't so the protection circuit comes activated.
you get red and green blinking

Then it goes to standby, red and off.

so something has happened to the lamp, or lamp ballast power supply.
Take the lamp out and check if all is OK with the 2 terminals in the connector, and the leads to the lamp are intact.

Failing that, I would suspect the ballast lamp power unit

I have an optima hd180 that will not power up. The projector was indicating a bad bulb, so I replaced that with a new one. Now it still will not power up and the fan does not come on either.


Problem w/ OEM bulb, it causes a lot of issues from my experience. Your ballast might have gone bad, hopefully it's just that. Check the voltage output of the ballast, make sure you're getting the proper amount.

Why would my projector refuse to start with a seemingly intact light bulb?


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.

Sounds like you lamp ballast has gone bad. I good way to verify this is, when you press power on the projector look inside the lens. If you see a small amount of light, then the ballast is good, and the lamp is bad. If there is no light then chances are the ballast is bad.

Unplug the TV for maybe 10 minutes, then turn it on. Sometimes these units simply need to recycle. If that doesn't work, you've likely got serious problems.

PLV-Z1 no longer powering up - Ready light is green and the Lamp light is red


I have a Sanyo XU35. Mine was starting up and showed a picture for about 15 - 30 seconds then shutting down. My lamp warning light was not coming on. When I put it in for repairs it turned out to be the lamp that needed replacing. The technician said it is not uncomman for the lamp to be gone and the lamp warning light not to come on. I got my lamp on e-bay from ping_ngo for a great price.
