If the lines you see are retrace lines, It means that the 200VDC are missing and not getting all the way to the video amplifier assemblies.
Did you touch the screen control settings by any chance before you replace the HV splitter?

Picture is bowed inward and looks like a 3d image without the glasses. I also have a green, red, and blue line curving across the top of the picture.


Looks like the focusing lens may have moved a bit or the projector lamp has gone weak. Get a technician to check up the projector.

There's very little you can do here.

Hi there, my dell projector 1800mp is not projecting an image on screen and it only black lines across. what should I do to fix it?.


After turning on the projector, press "+" and "-" buttons on the control panel

simultaneously for 3 seconds and release the buttons when screen goes blank.

2 Press "+" and "-" buttons again to exit the diagnostic mode.

3While in Self-diagnostic mode, the screen will run a seven-color-cycle test as

following:

Red--> Green--> Blue--> White--> Watchet Blue--> Dark Green--> Yellow.

Ensure that the colors of the test pattern are correct. Contact Dell if the colors are
not displayed correctly.

Purple and green scrolling lines


This may be a mechanical or electronic problem that is dealing with the sync of the colour wheel. There is basicly no colour lock. This may be the replacement of the associated circuit board, or the motor assembly or the colour wheel.

The link below is describing about how DLP technology works. They are relating to a front projection type. With the rear screen type, the basic technology is very much the same for decoding the pictures from the TV signal.
