HLP4663WX - Image has hourglass effect

[grayfox]

hello!
right of the bat I have to advice you might have to change your ballast :( this has nothing to do with the "hourglass effect" I just believe it to be weak because this is a recurring issue with Samsungs and a weak ballast can only power a weak or spent lamp, and when you put in a new one it is mercury rich and cannot power on :roll:

as to the effect you are getting on the screen if it is fixed by physically manipulating the screen itself, this can be a misalignment with the projector or the screen itself, you mentioned it has been moved around, is the screen perfectly flat? or is it concave at some point???

Was the original post delted then?

The issue I am having is that the image has an hourglass effect. I am in the factory service menu... There has GOT to be an adjustment for pincushion in here somewhere.
Anyone know which one it is???

with this being a RPTV I have not heard of such an adjustment as it is with CRTs... :(
