I sent my 7000e to JVP service at Marrickville Sydney ; needed a new pcb board from Japan ; hope yours is an easy fix . how much does it cost u?? i hope the parts are not discontinued yet otherwise this will become a piece of electronic junks (crying)

That's not to say your problem may not be totally different- as the circumstances seem totally different . They have to have spares for a certain legislated time I believe so let them make a quote before deciding . Good luck ; if you go with my mob quiz them about return delivery beforehand ; they much prefer pickup at the depot rather than risking damage on the return[ which I had to arrange ]
wooferocau Posted February 19, 2020 Posted February 19, 2020 I had this happen on an N5 that i had here ........ Seems JVC still have issues with the "Auto Iris" mech... From AVS this morning.... I don’t think this has been covered in this thread, although I haven’t read every single post, but I did post my problem some months ago and didn’t get a response so I assume this is not widely known Problem Major bug with Auto Iris function that can lower your peak output by 30 nits or potentially more. Auto Iris gets stuck at some lower value and reduces max output even if you switch to manual and completely open iris Fix On manual iris mode completely close and then open iris (may take a couple of repeats) After doing this max output returns to normal. Background I purchased an NX7 in August 2019, unfortunately it developed the Blue Line issue and needed to be replaced. Replacement arrived 10/15/19 and seemed to have similar measured output but within weeks was obviously dimmer and measured that way. I complained to JVC and they required the unit be shipped in for testing. JVC tested for a month and eventually sent me another unit, but said they couldn’t find anything wrong, but it must have measured low to them too, otherwise they wouldn’t have sent me another unit. Replacement arrived 12/16/19 - this unit had major lens shift issues and JVC immediately sent me a replacement Replacement arrived 12/23/19 this unit had similar initial output levels to the other two projectors It initially measured the following through my DCR HDR (BT2020) - High lamp/P3 = 106 nits Within a few weeks it was at HDR (BT2020) - High lamp/P3 = 90 nits Then a few weeks later @200 hours it was HDR (BT2020) - High lamp/P3 = 74 nits I was tearing my hair out. Did I have a bad bulb? Did I have another bad projector? Was everyone dealing with this light loss? I reloaded my init file and did a factory reset to no effect. Finally a few days ago in talking to Kris Deering he asked if I had tried closing and opening the iris. Wow that was it. Now HDR (BT2020) - High lamp/P3 was back to ~100+ nits Yay!!!! Kris mentioned he had seen this on two units and the only way to be sure it doesn’t happen is to leave iris on manual. Once again thanks to @Kris Deering Cheers Stephen

betty boop Posted February 20, 2020 Posted February 20, 2020 its not a new thing, am sure i remember javs with the issue with previous gen...can happen. not that seen it either on previous or current gen. but good to know if ever happens ...just open and close .... 2
franin Posted February 20, 2020 Posted February 20, 2020 Yeah I agree good to know. So far so good with mine.

Do I need to change some setting to stop the grinding? Or am I shutting down wrong?

Or am I shutting down wrong? hi wasm, I note below from kris, in responding to someone re potential iris lockup( he’s only seen the problem twice in a lot of projectors and like I mentioned it was reported issue with previous model, however he states why possibly could be an issue powering off in hdr and powering up in sdr ... so could be related to shut down startup ... but not something I’ve seen or have many as Kris says ... “Glad it helped. I am not sure if Auto iris is the root cause of this, I have lots of clients that use one of the Auto modes with no issue. I think one thing that may cause the issue is powering down the projector in one mode and starting it in another (powering off while in HDR and then powering on with a SDR signal) as the projector may get lost on what setting the iris was/is in. I know this was a problem with the previous model and was reported here, but this is just a guess. I calibrate LOTS of JVC projectors and I've only seen this problem twice total outside of yours, but doing the manual iris adjustment fixed it both times. So like everything else out there YMMV.“ 2
betty boop Posted February 21, 2020 Posted February 21, 2020 @WasM see bobof post below it relates to his 7900 also claw recommendation following ... try it see if helps bobof “If it is related to the issue I saw, then I think you might get back to the same situation after the passage of time if you use it the same way. On mine it wasn't auto iris causing it, it was turning the projector off in one mode (eg with SDR playing) and turning it back on in another (eg with HDR playing). Since stopping doing that I don't see it behaving this way. I still believe this is an issue with the design of the auto HDR mode selection logic and motor control. To lose light like that for it to be the same mechanism I saw I think you'd have to turn off in SDR mode and turn back on with an HDR source playing. On my X7900 doing that leaves the lamp iris in the position it was in for SDR, but the projector believes it is in HDR position, so you progressively "lose" lamp iris opening. Each time you do it the lamp iris will end up a bit more closed. Closing and opening the iris would often fix that sort of thing as it likely got to the end of travel, couldn't go any further, and so when you went back in the other direction the range of travel is fixed. On the X7900 I have that hitting the end of travel sounds horrible... “ claw “This issue was discussed with the e-Shift projectors as well. Those who followed this ON/OFF procedure never encountered the issue: Projector is first component to power on, wait for the D-ILA splash screen, then power on the AVR and player. Projector is last component to power down, wait until No input label is displayed, then power off.” 1
betty boop Posted February 21, 2020 Posted February 21, 2020 I as routine always do projector on first...then everything on after. And by routine everything off first projector off last so probably why never seen it 1
betty boop Posted February 22, 2020 Posted February 22, 2020 @Davo1972 seems 12 months on been enjoying the n7 being one of the first to get one....you were the trail blazer with one. still got that loving feeling ? how you finding it 12 months on?

You have to turn up the volume (poor iPhone recording) and go the 23 second and 52 second mark to hear the stuttering/grinding sound. Edited February 22, 2020 by WasM

Jimval Posted February 22, 2020 Posted February 22, 2020 (edited) On 29/01/2020 at 11:13 PM, Jimval said: Thanks Rich. Much appreciated and no need to contact Westview. I contacted them today and they confirmed they have received the DD board from JVC KENWOOD. They are now waiting on JVC Japan to send them the correct firmware for the DD board. Board replacement is consistent with what the manual states regarding the flashing of the left & middle leds on the unit. I.e. a board error(s) I hazard a guess another 3-4 weeks of me whining to JVC KENWOOD would have been too much for them, thus the priority shipping to get me off their back. cheers Jim My faulty N7 issue has finally been resolved. A week had passed since my last post above and I was still waiting for the call to pick up my N7 following DD board replacement, firmware update & retest. I therefore called Westview & then called JVC KENWOOD on what was the hold up. i was told that they were still trying to determine the correct version of firmware for the version of DD board that was shipped from JVC Japan. Apparently the configuration data of the DD Board has to be read from its EEPROM to determine the right firmware to drive the DD board’s hardware. Installing the wrong firmware would brick the DD Board and we would be back to square one, so obviously it was critical to get it right. Note that the DD board firmware is only specific to the DD board which is different to the firmware that the end user can install. As a side note, I was also told by JVC KENWOOD that they discourage the end user from performing firmware updates In case something goes wrong and it bricks the unit. This shouldn’t happen if it is a clean install, but may happen if files other than the firmware are on the USB stick. IMO the DDBoard firmware version is JVC Japan’s responsibility, to provide the firmware information associated with the DDboard, not JVC KENWOOD here, who were left to fend for themselves as they also told me mine was the first N7 they had come across with a faulty DD board that needed replacement which might also explain why they don’t stock them locally. Throughout, the person I was dealing with at JVC KENWOOD here was informative & helpful. I believe this was the guy that was on annual leave because it was obvious things weren’t happening until he stepped in. He was well on top of the issue and gave it priority. JVC should pay him more. Anyway I was told it would be resolved by the end of that week. Later that week, I received a call from Westview asking me where I would like my new N7 to be delivered by JVC KENWOOD. I can only assume they were unsuccessful with the firmware update or it still hadn’t been resolved and they thought I had waited long enough, but most likely to get me off their back! I picked it up instead and the rest is history. Enjoying the N7 ever since. i almost forgot how good those jaw dropping images it puts out are. As mentioned previously, I have no issues with the N7. I think it’s brilliant. Many thanks to Rich for helping progress the repair. cheers Jim Edited February 22, 2020 by Jimval 5
TrueRealist Posted February 22, 2020 Posted February 22, 2020 Great news Jim. Pity this had to be so painful. Hopefully all parties involved have learned from this saga and customer service will be what it should be in future. Always a shame to see a fantastic product let down by poor customer service and support. Enjoy your NEW N7! 4

Since I took that vid I've manually open and closed the iris from min to max, cycling about 4 times. Then set it to -4 and left it on Auto. I've now followed the procedure to turn PJ on first and turn off last. All that was last night. I'll give it another whirl today and take another vid, this time with phone case off. I normally turn everything on at the same time so that could be an issue. 1
