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

[Norman Hurst]

Warped shadow mask?  They can warp from excessive beam current.  Or dropping.

Here’s one that’s had me scratching my head today...
 
Just bought this monitor for the too-good-to-be-true price of 69GBP (inc 
delivery).  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.
 
I’ve had the lid off and it’s not like someone could have wrongly plugged 
RGB to the CRT base board (for example).  The OSD menu is affected so the 
wrong colours problem has to be in the RGB domain.
 
No problem with rejecting, getting a refund, etc – but has anyone come 
across a similar problem with these monitors?  Very weird fault.  (But 
not once you understand it, of course!)  Current thinking is that it must 
be a duff CRT.
