Hello, When doing the 9 point convergence on my tosh 42pw23p I can get most of the points pretty good however particularly down the left of the screen the convergence seems blurred. Mainly on the blue gun the shadow is on both sides of the crosshairs. Is this normal and should I just get it as central as possible or is there a way to focus the blue gun on these crosshairs? Another quicky in the service manual it says that certain screens and menus require you to press the -/-- button on the remote, but my remote doesn't seem to have one, anyone know which button the manual is referring to? Cheers in advance Paul.
