You might do some heavy digging to see what the word is on PJ reliability.
In my experience, I’ve sold about 20 brand new JVC projectors in about 2 years period. About 8 of them (lamp and laser) had malfunctions from 2 month - 12 months after purchase (one NX9 required repairs after 2 month of purchase).
I know because every time a repair is requested from the client, I get a phone call from the JVC service rep in New York to confirm that I did sell those JVC. We’re on a first-name basis (don’t want to mention his name).
Although he seems like a really nice person, that’s a lot of phone calls that I never want to get.
I’ve been using PJ since 1992. My $10K SharpVision PJ lasted about 12 years (lamp literally exploded). My $6K Optoma failed 3 times in 3 years - piece of crap. My $3K BenQ lasted about 5 years until I replaced the original lamp, then it was never the same again. So far Epson has been great, so hopefully Epson is extremely reliable, especially with Laser (fingers crossed).
I’ve never had any experience with Sony PJ, so maybe Sony is also reliable.
I don’t know if there is any consumer reports of PJ Reliability. Would be nice to have before spending $18K on a JVC NX9 and needing repairs after 2 months.
