|
|
I have an Ampro 4600 and the alignment of the red/blue to green is impossible to align on the far left side of the screen.
Are there an Width adjustment screws on the red/blue like the height ones for red and blue?
I have been messing with it for months.
Also, what do the 3 dials do on the Horzontial output board?
Did I accidently change this once when I was working on my PJ and that is the cause of my left width alignment problems?
If so, how in the world do I know what to set them back to?
Thanks for the help.

Use the width coils on the yoke interface bd to make the horiz width the same for all three colors. Lenses focussed and registration turned off.

They are used to make the horizontal linearity as even as possible.

Probably not. They effect all three colors pretty much the same.
"If so, how in the world do I know what to set them back to?"
Input UXGA, 1080p, or something with similar horizontal frequency (50-75KHz) and adjust SR3 so left side has size similar to right side. Change input to 540p, 1080i, 720p or similar horizontal frequency and adjust SR2 for left side of image to match right side. Change input to 540i and adjust SR1 for best horizontal linearity.
