Wow Clarence, I never expected a post like this from you.
BUt I agree 100% with 1031 and Macguyver. From what I understand, Sony did in fact NOT support the G90 for the 7 years after discontinuation (2004). ( I could be wrong that it's mandatory to support a product for 7 years after it being discontinued, but that's what Barco told me this January when I inquired about taking over worldwide BArco service, that they were bound by law to support their CRTs until Jan 2016, 7 years after the last CRT was produced this January 2009. Sony's IC421's failure has been well documented on my forum, the problem is, there are too few sets out there, and most are indeed being pulled out by the original purchaser who at this point don't care about lack of parts. That leave a few 100 G90 owners that DO care, some of which paid $35K for the damn product.
As for parts availability, yes, the vast majority of parts for any CRT projector out there can be found online, new in the box, whether it's the local electronics supplier, newark or even eBay. You can't say that for the custom chips found in the Sony, made for the G90 only, by Sony for Sony.
Now, you are right, for the special parts, be it Barco or Ampro, some are indeed not available either, but enough sets were made so that there's a surplus (even if most are currently in my basement) to keep projectors going for say the next 5-10 years. Again, the Sony G90 is the exception.
I personally have never had a problem with Sony products ironically. My car stereo that I use an average of about 4 hours a day is still going strong after 7 years. THe point is, even if I only affect 100 other people when I say that I won't be buying any Sony product again, at least I'm making a difference as a consumer by stating an opinion. It might not change anything in the big scheme of things, but it's my way of telling a large Japanese manufacturer that their crappy support of a flagship product isn't tolerated by someone like me.
Frankly, I'd love Kal to put a banner ad up on my site to not buy Sony product. I'm wondering if any bigwigs would be alerted to it at Sony, but even if I don't do that, my own personal dollar is speaking for me when I buy elsewhere.
