This is a convergence problem that is not easily repaired by a homeowner. This unit should see a servicer.

The convergence is off. The convergence is basically the assimilation of the image on the screen from the three "guns" behind the screen. There should be a menu option to align the convergence in the image portion of the menu. If this does not fix the issue, then your convergence chip might be on it's last leg.

How can I get the best video image quality with Nec np1000 projector ?


Your best option is using the COMPONENT IN input of the projector (Y, Cb, Cr). Though the highest video signal the projector will support is 1080i.

You have a convergent problem, where the red, blue, green projector lamps are out of synch. See: http://www.youtube.com/watch?v=esk4nYZKFcg for a pictorial on how to fix convergent.

I have a 61'' Panasonic tv that is showing green and red outlines around the figures on the screen. It originally started as just green outlines. Any ideas on what the problem is would be great. Thanks

I have a philips projector model lc4433. I need a part but I am not sure what it is called . It is part of the prism system. It is one of the small prism's/mirrors . There is a set of 3 on a mount behind...


These parts are fixed during production and are not individually replaceable parts. The entire prism assembly needs to be replaced. This is an unusual repair request though. Why do you think this needs to be replaced? Is it physically damaged? If so, there will be additional convergence adjustments and alignments that will need to be done as well. This will require somewhat specialized test equipment to perform. This unit should be sent in for service.
