    Hi Folks,

    I am having my first foray into crt projection :thumbsup: But i am incredibly uneducated in them :blush:

    I bought THX1138s bd800 from him and have gotten as far as raster centering but i have no clue what to do with regards to this. It says to reduce the contrast and increase the brightness then centre the raster on each of the crts :rolleyes: I look in the lenses but i have no idea what i am meant to be doing :suicide: Can anyone please help...

    Yours stuck in the spare bedroom scratching his head :laugh:

    When you look into the lens you will see the raster and it will have dark edges where it isnt illuminated. You need to be gettng eaqualish distances on the left and right, then equalish distances on the top and bottom.

    Send a 0ire pattern from AVIA or Video Essentials to the projector. Then centre that image as described above. Do this as advised with contrast at 0and brightness HIGH.

    I'm back at weekend. Might be able to stick head in for you to check it. Email me with your address again and I'll see if I can work out a time and date.
