It doesn't make much sense to say everyone with an HR34 is affected. I don't have this issue on my HR34. Other than a very rare pink flash as my TV first turns on I don't have this problem.
IOW, just because someone has an HR34 doesn't mean they have this issue so you can't really say how many are affected.
Why do some have this problem and some don't? I don't have a clue.
I don't see where anyone said that "everyone with an HR34 is affected."
In fact, what I said was that assuming only a 5% HR34 penetration rate, and if only 5% of those HR34s were affected, that number would equate to 50,000 affected HR34/TV installations, which is one quarter of one percent (.25%) of the overall installed base. Is that figure too high? Okay, let's halve it to only one eighth of one percent (.125%) and that still equates to 25,000 affected units. Or, again, halve that to one sixteenth of one percent (.0625%), which, to me, is a ridiculously low percentage, and that's still 12,500 affected units.
The bottom line is that when you are dealing with such a large subscriber base, even tiny percentages equate to relatively large numbers.
Oh, and if you are seeing a "pink screen" at any time, you are, indeed, affected, just not to the degree that others seem to be. Lucky you.
