I asked my partner to come and have a look and I had to really point it out to her for her to notice it and even that she had trouble seeing it. I haven't noticed it one bit in content (just when there is a lot of of white content, e.g. google.com and can notice it even here but less pronounced) which is the main thing so unless it gets worse I might just wait until I get it calibrated in a few hundred hours and ask the calibrator's opinion. Thanks for your help. Id keep your retailer advised.... os they are in agreement as well on your path... just so they dont come back down the track as in ... should have told us upfront ... keep in mind if it is DOA for some reason, and this can happen with any projector / brand... they are such delicate things... but its easier and best just getting it swapped out straight up. that cant really photograph and really hard to see by anyone else...ie take some convincing probably doesnt help ! but still i think its better to just be upfront with these things...
interweb66 Posted May 15, 2020 Posted May 15, 2020 (edited) Thanks for following up, I just passed it on to the dealer. Unfortunately I only have my pixel 3 to take photos with but when I look through the phone screen at the projector screen it can't even pick it up, it's just pure white haha, so I do wonder if I am being too sensitive :). Edit: I took a few more photos which might show it better: Edited May 15, 2020 by interweb66 1

Edit: I took a few more photos which might show it better: That is definately not correct. I have seen this on several of the "N" series unfortunatley!! It really is a lottery with this series , some are OK some are "Borderline" depending on the users tolerence level, and some are just outright "Faulty" ! Panel iniformity isnt a strong point of the new series, its up to the users to decide just how much they are prepared to tolerate the defects......myself....it would be going back!!!
wooferocau Posted May 15, 2020 Posted May 15, 2020 Just ran one of your images through Photshop .......you CAN see the centre versus the outer edges .. 1
interweb66 Posted May 15, 2020 Posted May 15, 2020 Thanks for having a look. While not quite that bad in person that photo really conveys what I am seeing in terms of a pure white centre and green tinge on the outside.

Yeah, i just boosted the levels of your original image to convey what you are seeing . Your orignal image on my Dell monitor shows quite prominatley the issue..
Quark Posted May 16, 2020 Posted May 16, 2020 The issue is quite apparent in your second lot of photos - I'd consider that unacceptable for a projector at this price point. It's a DOA IMO - insist it is changed over for a new one (not repaired or swapped for a refurbished one). 1
betty boop Posted May 16, 2020 Posted May 16, 2020 agree more apparent in 2nd lot, definitely treat as DOA and best time to do that is upfront now.... later it jsut gets harder after having owned for some weeks months etc ... and does it end up getting sent off to get fixed or replaced and all that...
interweb66 Posted May 16, 2020 Posted May 16, 2020 Thanks guys, at least I know it's not just me, some of these things can be tough to work out. Though my X5500 is not like this at all so that was kind of telling in itself (even though this is a completely different hardware platform). Have messaged dealer, though being Saturday not expecting anything to happen until Monday. I will put a few more hours on it just to see if it settles down but I am not holding my breath. Ah well, these things happen. I had a similar issue with an old Panasoic S60 plasma except it was pink, not green and a know problem with the panels so I learned to live with it, but that was considerably cheaper 1

However JVC have to get the projector back first, get the service centre to assess, find error codes etc, send to JVC, then JVC reserve their rights to repair or replace as per accc rules. 2
oztheatre Posted May 16, 2020 Posted May 16, 2020 There appears to be a grey area in the rules when it comes to what is a 'minor fault' vs 'major fault' JVC may claim the faults, whilst there, are minor as the projector still works etc. So if deemed minor, they have the right to repair or replace. If you have a minor problem with a product or service, the business can choose to give you a free repair instead of a replacement or refund. When you have a major problem with a product, you have the right to ask for your choice of a replacement or refund. For a major problem with a service, you can choose to receive compensation for the drop in value below the price paid, or a refund. But it has to go back regardless, they, or any other company anywhere, will not just post you a new item because you said it was faulty. It has to be returned as they have policy to follow also. Same for any retail product. Either way JVC Kenwood have now been informed. 1

interweb66 Posted May 16, 2020 Posted May 16, 2020 (edited) As expected the issue hasn't gone away after more use. It's a shame as other than this uniformity issue the picture it puts out is just stunning, it's a real nice upgrade from the X5500. Something else I have noticed and I am not sure if this is normal. In low lamp mode it's very quiet, however at times it sounds like a secondary fan comes which makes it noticeably louder (somewhere between low and high lamp noise), this can last anywhere from 10 minutes to half an hour. When switching to high lamp (while the secondary fan is running) I can still hear the secondary fan also. I have an air conditioner in the same room but the room is an odd shape and we have a curtain partitioning it (though I do have it open a couple of metres at the moment). For reference it's mounted on a shelf about 30cm away from the wall. Is this normal behaviour or do I need to install more cooling? Edited May 16, 2020 by interweb66

I can't to be honest recall any fans coming on / off but then mine is mounted higher up and good couple of meters plus behind. if in closer quarters maybe something id notice.... just put a probe near the projector and log temps... see how things go... if a closed room and with heating or lack of cooling... temps can rise generally overtime.

Exactly this. I know the fan you mean and it only comes on when the room gets too hot for the projector. For us that's only really in Summer, doesn't happen over Winter. Got any heating vents or the like in your room that could cause it to kick in? 1
interweb66 Posted May 17, 2020 Posted May 17, 2020 (edited) I have got a thermometer up there now and will start logging temps, the projector is at the back of the room about 2-3M from seating position, pretty close to the ceiling (room height is only about 210cm). Underneath the projector is a receiver and a sealed cabinet with a bunch of consoles and AV gear, I have installed AC Infinity fans in the cabinet and the temp in there sits around 26C (when equipment is not in use). The room is a rumpus that's downstairs in the house, room is completely sealed (door sealing and windows and sliding door have secondary glazing and all blacked out), double brick walls on a concrete slab. I have the AC turned on to 25C but as mentioned earlier there isn't a direct path from the unit to the projector for air to follow, I was considering getting a vornado or other type of circulator fan to pump air into the projector space. The room backs on to the garage so also thinking of cutting a hole in the wall to exhaust air out of the room (or bring in). It's good to know this fan is normal (depending on thermal conditions), which tells me I need to improve circulation/cooling. Am I right in assuming this projector puts out a fair bit more heat than the X series (e.g. my previous X5500)? Edited May 17, 2020 by interweb66

My receiver sits on 26-27 degrees when the PJ is on and working so that's pretty high for idle. Have a look what it is when everything is on. I have the AC Infinity Aircom cooling my receiver and it does a great job, but my receiver is nowhere near my projector. Edited May 17, 2020 by cindernat
interweb66 Posted May 17, 2020 Posted May 17, 2020 (edited) Thanks, will see how it goes, the cabinet is actually 23C at the moment. I have the thermometer behind the projector on the left side (standing at the front of the room looking back at the projector), as that side seems to pump out a lot more hot air than the right side, not sure if that is something by design or another indicator of inadequate circulation, currently the thermometer is registering 26C and the projector is just humming along in its usual quiet low lamp mode.

Cool. I find it can take an hour or so before my projector heats up and the fan kicks in. The room starts off quite cool then it gets really warm in there. I think this projector (maybe all projectors, this is my first) run hot in general and need decent ventilation. Mine doesn't have anything around it and has a decent distance behind it but still runs very warm. I've learnt to put up with it. 1
interweb66 Posted May 17, 2020 Posted May 17, 2020 (edited) Thanks again, really helpful to know it's by design rather than an issue. Now I can work at trying to solve/mitigate it and learn to live with it :), for now I will just keep monitoring it. Also it's pretty much a moot point when content is playing, can only really hear it in quiet scenes and it still doesn't get as loud as the "high lamp/high altitude" modes.

betty boop Posted May 17, 2020 Posted May 17, 2020 anyone watched knives out on uhd blu-ray ? holy cow... ! what a picture...this is rich... sumptuous, contrasty and the detail ! just whacks you in the face, can't believe it. What is amazing is while its a 3.4k-5.1k source a bit of a tragedy that it only got a 2k DI can't imagine how much better could have been with a 4k DI ! some screen shots, and can tell you this. while posting these reduced by the website on the web, looks even more amazing with own eyes straight off the screen... really shows of these JVCs... 1

Out of curiosity, shouldn't dealers provide a direct swap for the customer (provided both parties agree that there's an issue) and have the dealer then sort it out with JVC themselves? After all, the sales contract is between the retailer and the customer.
