I have read many threads about convergence....but, what can one do when the on screen crosshairs will not move enough to clear the picture? My red is fine it is the blue that will not go enough to the left to align properly....can i manually adjust the tube inside? then fine tune it? My closest tv guy is 65 miles away...if i trailer it to him, it will bouce outta whack on the way back. I have looked for a SM to no avail...i moved this unit 25 feet on carpet now it is a bad picture....Akai was no help. I have not tried the 1 8 3 menu yet, but not sure it will let me adjust it that far either....any help is appreciated....
