Not just british had ripple issues.
A long time ago I had a suddenly dead very expensive ($5K) Hitachi monitor just before a critical demo.
I had a contact # for a real tech support person from a prior issue so I called him and started to descibe a couple of preliminay checks I had done.
He stopped me and said:
"see that brown electrolytic cap near the flyback"
when I said yes he replied
"that's your problem, a good one would still be blue".
Changed it out problem solved. Received updated boards for our units we had a short while later.
