To reset the lamp timer:
1) With the projector plugged in and turned off, press the 'ON/STANDBY' button to put the projector in 'STANDBY' mode. NOTE: You have to press the button on the projector itself, you cannot use the remote for this step (this is not clear in manual).
2) Now, using the remote, press the following keys in order: RESET, <--, -->, ENTER.
3) Timer should now read '0'.

mine does the same thing but i can see the whole screen it's just half height full width, above solution about zooming to 1X is what i've been doing to fix it for the last 6 months, needs to be done every time I turn the power back on. Anybody know of a more perminate fix?
Now my power supply has gone have the projector in pieces, found a failed on transistor but because it's over heated can't read of it what type it was....
Already replaced two blown diodes in the main H-bridge
Looks like one coil will need rewinding.
If anybody has one in pieces I would be great if you can help me work out what the blown transistor was.

Hi there

This problem can only be fixed properly by replacing the Mainboard.

I also have the same problem -- the fix is to replace the optical block ( Internal lamp engine ) which is a $1,100 part. I just purchased a used projector for half the price of the part.

SOURCE: Vertical lines on projected image from a Dell Data Projector. White vertical lines are appearing at even spacing across the width of the image projected. At a loss to how to fix this. Any ideas as to

that is due to lcd filter units , try to align, precision work
