My HD20 also broke after about 1000 hours. Their estimate is $703.00 to replace main board and lamp module. Image shuts off automatically after 3 mins of starting. Lamp fail led goes solid red.

I opened my emp x3 because it wont turn on. there is some kind of strip that runs from the cover and seems to connect to the main board but it is disconnected, is that the problem? Where would I connect...

The wiring strip you are referring to runs from the control board on the top of the projector to a slot connector on the big circuit board below. That connector is on the edge of the big board facing the front of the projector, about two inches from the left (when facing the projector front). You'll know which one it is because it has black piece on top of it that pulls up. To reconnect the strip, pull up the black piece and slide the blue bottom part of the strip in the slot opening on the front of the connector. Then push the black piece back down.

Projector will display image, but it has vertical lines running through the image. If a heavy object is placed on top of the projector, the lines disappear and will not come back.

This likely a conncetion problem between the main board and the light engine. The added weight could be making the connection complete. You could open the projector and remove the ballast, power input board, and shield to remove the main board and clean the part that connects it to the bottom of the rear of the engine and then reseat the connection, BUT, this is a major task if you don't know what you are doing and is best left to a tech or living with the weight being on the unit.

InFocus LP70 color problem

try resetting the settings to factory default through the menu. if there's still a problem, take the cover off. if you look from the back of the machine, inside on the bottom left, you'll see the main board attached by a large white plug. use something thin and non-metalic to push the bottom of the board towards the plug to tighten it. now do the same to the other side of the plug. this should solve it. if it doesn't, you need to replace the main board.

Black and white image on infocus x3

first reset the settings to factory default (menu, settings). if that changes nothing and the colorwheel is still in tact, the main board is bad.

White vertical lines in image w/ 2 inch black bar horizontal.

the black bar is from the light tunnel collapsing. the white lines are from the colorwheel or the main board has a cold solder joint. replace the tunnel and colorwheel and have the main board looked at.
