Sony admits a CRT Design flaw in Memo! | RGB Lights of Death follow up
Channel: Retro Tech

This is a final follow up to the Red, Green and Blue Line problem that occurs on many Sony Pro Trinitron CRT Monitors.  I have received a copy of the internal Memo from Sony that admits the problem and how to fix it.  This was sent out in the form of a technical memo to repair techs and clients in September of 2001.  

Unfortunately this flaw affects a large amount of Sony Pro Video Monitors.  There is a temporary easy fix, but it can eventually destroy most of your PVM!  All of the sudden your PVM or BVM will stop working and need a new Flyback Transformer and a couple other ICs on the main board and the power supply unit.  Please make sure you don't simply ignore this problem.  It's much easier to fix ahead of time.

Here is a detailed video on how to do the preventative repair as well as details on the Capacitor Values:

List of Monitors affected:
PVM 1350, PVM 1351, PVM 1353MD, PVM 1354Q, PVM 1453MD, PVM 1454Q, PVM 1953MD, PVM 1954Q, PVM 2053MD, PVM 2054Q, PVM 14M2, PVM 14M4, PVM 20M2, 20M4 and possibly more.  If you have a PVM similar to any of these listed models, you more than likely will have to deal with this issue.
