[QuadList] Sony PVM-14L4 - RGB Appearing as GBR and Purity Problem with this HR Trinitron Monitor

[Dennis Degan]

		I offer:

	Most likely, the purity magnets are out of adjustment.  As for the color channel mixup, I've never seen that before, unless it's operator error: i.e., plugging the wrong channels into the the wrong sockets.  Check to make sure what you THINK is RGB is ACTUALLY RGB.    ;)

Two problems – the colours are “rotated” so that RGB is actually appearing as GBR and there’s what looks like a purity problem towards the right of screen (degauss operates, but doesn’t cure the problem).  Pic attached.
