We were getting no light from the lamp in our lp130 projector, so we thought maybe it was the lamp, we have replaced the bulb and still we get nothing from the projector. It does power on and we get the green power light but nothing else.

HOLD THE POWER SWITCH ON BOTTON OF THE UNIT PLUG THE POWER CORD TO THE ELECTRICITY SOURCE RELEASE THE POWER BOTTON AFTER 10 SECONDS AND THEN TURN ON THE UNIT... OR YOU MAY GO TO THE SITE (freepatentsonline.com) search the brand of the device....GOODLUCK.
the connection that the lamp plugs into backs out of place preventing the connection from being made. you will have to remove the top. with thetop off, install the lamp and look to see if the lamp connection is going into the connector on the lamp housing. if not, you can get a flathead and push the connector into place on the lamp housing and hold it there while pushing the lamp into place. to keep this from happening again I always used to melt the connector to the lamp housing with a soldering iron.
this used to be my favorite easy repair. Reset the lamp hrs and you may have to upgrade the firmware. If that fails, try this and your old lamp may still be good. i'm not making any promises,but there could be a simple solution. remove the rear cover. then push the release in the slot on the front cover with a screwdriver (this is opposite the lens side.) remove the cable coming from the top cover to the main board. remove the top. Now, look at the lamp where it connects to the connection at the rear of the lamp housing. Now take the lamp out. Put it back in slowly and watch to see if the male part on the lamp actually makes the full connection to the lamp connection on the housing without pushing the connection backwards. If it does push back, then that's the problem. you can hold the connection on the housing in place while you seat the lamp all the way. I used to melt the connection to the housing with a soldering iron so when you put the lamp in it wouldn't back out again. However, if this doesn't fix it it could be the colorwheel not working. If the colorwheel doesn't spin, the lamp won't light either.
there is a problem with the power to the front fan from the main board. there are 3 wires going to the fans: one power, one return, and one signal. if the main board reads no signal from the fan's speed, it'll shut down. check the power going to the fans and the signal. you may need to replace the main board.
the ballast is bad. the fan turns on for the colorwheel, but when the lamp doesn't strike, the fan and colorwheel turn off until it tries again. unfortunately, there are no replacement parts for the lp130.
