A few members have been posting Sony as having gamma drift and also adding "gamma is not correctable", that false remark is intentional and has been used quite a lot by those on a mission . Sony does have gamma drift, which I consider typical and the remark posted often that," it is not correctable" falsely leads many believe this is true . Negative marketing is very pervasive here on this forum, the reasons are many.
People are just tired of getting burned. Most TV's you just set them up and they just work for years and years, with projectors there are so many more issues. Epson with the failing power supplies and dust blobs, Sony's with the contrast degradation, it's not like they were isolated cases, there were hundreds of people with the issues, if not thousands on the Epsons. So don't agree it's negative marketing, it's just people fed up. Based on what we know, it's not completely fixed, but may take a lot longer on some models to appear than some past models. If you have unlimited money to keep buying new projectors, then it doesn't matter, just buy whatever and throw it away later, because some of these projectors are throw-aways almost.
These are not small issues or about fanboyism at all, these are about people buying $5000 to $25,000 units with massive defects, a similar defect as to why Sony already lost a class action lawsuit in the past relating to other QC issues. Given the poor history of Sony's LCOS panels, and the troublesome past of Epson's QC issues, it's not fanboyism.
Although JVC did have some issues of their own as well, the difference is JVC's issues didn't devalue your projector by 95% or make it not turn on. Sure, a few people have had severe issues with JVC, but it was far from the norm. In the Epson threads, like every few posts it's another dust blob or failing power supply (it's literally almost the norm), or people on their 4th refurb attempt. Not saying no-one should ever buy an Epson (that's their decision), as you can get some really good deals, but it's definitely not the right choice if they are betting on longevity.
I can tell you from experience, JVC's can last a very very very long time (and with zero dust blobs or power issues), whereas I wouldn't put that bet on an Epson or Sony as much, especially Epson. Maybe the newer Epsons are better, who knows.
I can buy some Sony's on Ebay that used to sell for over $8000+ for almost nothing because of contrast degradation where the seller admitted the contrast was probably 300:1 or that the panel looked burned out. They don't pop up commonly, but I've seen a few, and if you watched Ebay close enough, you'd have seen it as well. I'm sure more common is sellers trying to sell them with bad contrast and not telling you they are bad. Per Ebay, the # of used Epsons sellers were selling just for parts was getting ridiculous at one point, there was almost no other projector that had so many broken units being sold for parts that I know of. Heck, there were more Epsons being sold for parts on Ebay at one point than I saw working Epsons (geeze).
If you buy old Sony's on Ebay, many of them are going to measure sub 2500:1 contrast levels, you'd better off buying a newer 4k DLP for less.
