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

[lee williams]

Hey Steve, 

If that is the monitor I think it is, there is a known issue with the multi standards board. 
The board fails every couple of years and the only fix is to replace the entire card. 

Had a couple of them here at CBS, the card runs around $750.00. 
Tried replacing caps with our failed ones with no luck finds what fails.

Card is located on the top of the unit, not really difficult to change out, just a money pit of a monitor. 

Try Google with the model and symptom. 

Lee

 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.
