Sony decided to save some money and used plastic lenses instead of glass. Nothing too wrong about this, plastic, when treated properly can do a close job. Problem with this set is that one of the lenses sat too close to the light bulb, give it enough time and the user started enjoying a nice green/yellowish blob due to heat induced warping. Better even, it gets bigger the more you use the set. Nothing like Sony to bring back good old memories of my high school biology class, watching amoebas running rampant on my TV screen.

They never did a recall, but quietly payed for all repairs whenever anybody called complaining about said blobs on the screen.

And yes, the replacement part uses glass this time.
