I purchased an Epson 6500 in 2009 and within 12 months started to experience image quality issues. A green and red band started to form on the bottom and top of the image. It progressively got worse so I contacted Epson who sent me a refurbished unit. I have had that unit now for about 18 months and am now experiencing the exact same issue. I once again contacted Epson who acknowledge the problem, but, have washed their hands of it because I am out of the warranty period...and they suggest my only recourse is to take it for servicing.
Epson go on to suggest I acquire an new Epson product in their email response to me. "Please keep in mind that in some cases, the cost of a new product may be a more cost effective solution than servicing."
I thought I had purchased a fairly decent projector from a good manufacturer, but given 'two' projectors have lasted less than a combined 3 years I would be very careful about purchasing Epson. The quality was not there for me and I find their resolution to a problem that is clearly systemic - unacceptable. I am starting to blog about my battle with Epson calling it David and Goliath - An Epson Tale of Broken Dreams. I believe that consumers must be protected from situations like this where the manufacturer clearly has a quality issue.
