Reader Question: Samsung DLP HLN5065W: Screen shifted during a repair
I used the instructions to replace the color wheel from this site, thanks. It took me about an hour and a half to complete the repair only because I took a lot more things apart before I found these color wheel replacement instructions.
The TV is working with no more screaming color wheel and a good picture, however the picture now has a gap at the bottom of the picture. It appears the projector is not aligned correctly to the screen. I did not find instructions on how to be adjuest the lens to insure it is correctly align with the screen.
I tried using the on-screen aligning but this only shifts the picture being projected not adjust the projection on the screen. I need to lower the projection to see the top of the picture and close the gap.
What is the best way to re-align the picture on the screen?

Hi.
This problem never happened to me in the few times I've performed this operation, but I have seen others mention it.
It sounds to me like a physical problem. If everything else remains the same, then the alignment shouldn't change with the replacement of a color wheel. The color wheel has nothing to do with the angle of projection.
The first thing that I'd check is to make sure everything is securely back in it's place. Maybe the chassis is a little askew, or a screw isn't tightened all the way?
Also look at the projector lens and make sure it isn't being obstructed at all by the foam sheath.
Finally, some people have made mention in the colorwheel replacement thread that some mirrors came loose. Check out the color wheel thread for talks of that. Search for "mirror" on the page to see what they said and did.
Good luck!

Hey Chuck,
Did you ever fix the screen shift problem? Mine has done the same and I need to correct the problem. Any information would be helpful. Thanks,
