The Peerless ACC570 Round Plate is structurally more sound, and the base's larger 8"+ in circumference rim offers much better sideways "sheer" support for a 48 lb Projector.

I don't think it's heat, sounds like an electrical issue, but almost as much chance it could be software.
The replacement units did not come with the same firmware.

Re blue bars - this was never reported by people with early versions of the firmware right? I’ve only read about it on here since the firmware update that gave us the Panasonic profiles onwards

If people had reported the blue bars issue since day 1 of release then it would smell of a hardware issue, but that’s not the case?

-Having the blue bars happen during a movie event is embarrassing and disrupts the mood, but maybe even worse would be during a live sporting event. It's 4th and goal with 10 seconds left, the QB drops back to pass and .... blue bars with the interception. Yes, we all have dvr's so we can rewind, but one halftime per game is enough.
-Even if the blue bars only happen on average every 100-200 hours, it could happen 20 minutes or 2 hours after the last incident. So it's not like you can watch worry-free for 100 hours after it happens.

Hopefully JVC can fix this soon and releases a public notice (could be simply in firmware notes) so we know it was diagnosed and fixed. If it turns out to be a hardware issue, that sounds like a really complicated problem that might involve a total recall (not the movie). Until we hear from JVC though, we don't know how easy or hard this problem will be to fix or if they even know how to fix it. That makes it hard to pull the trigger on a purchase.
From what I see there is no way this is happening often at all. This thread would be lit up like a Christmas tree if every projector was effected. I have seen maybe 3 or 4 cases in here unless I am not remembering correctly. From our own clients zero.

I was thinking the same thing. It does seem like the issue was introduced with later firmware. Mine came with 2.04 and it appears (at least on this thread) that most users who experienced the issue had 2.01 or later. Maybe it's just wishful thinking on my end by hoping it's just a firmware issue.

That being said, I haven't seen the issue since upgrading to 2.07 (though I know a few owners have). Fingers crossed

Especially since the problem manifests intermittently for the most part. Is a replacement unit not seeing it due to different firmware? Is a replacement unit not seeing it because the person hasn't recreated all their preferences/calibrations? Do the calibration settings in general play a part?

I guess I just keep leaning software because after years of PC and server configuration and maintenance I just don't generally see hardware cause such an intermittent issue that goes away for a long period of time with just a power reset. But like you say there is no way to really know. At least not without debug data.
It happens with PC parts too, it's just not as common because the volume they are dealing in is so much higher volume than things like projectors. The problems are spotted quickly in their initial RMA process and they have to correct them fast because if you are selling $100 to $200 part and getting bombarded with RMA, you're losing a lot of money quickly. If you always order the earliest runs or v1 revisions of motherboards, I've seen similar things happen, like random reboots every 2 weeks from overheating bus controller, or just compatibility issues with firmware, or you get a bad memory chip and you get weird BSOD's.

I've seen the vertical lines issue on 2 projectors and three times on PC's. On the PC, two times it was heat related and once it appeared to be a faulty capacitor. On the projector I saw, it was a resistor and the problem was self-fixable by replacing the resistor, as several people did in the forums. The bad resistor was confirmed by the manufacturer (Mitsubishi) and they even sent out a diagram to repair shops so it would be easy for them to fix the issue. The other projector that had it, I have no idea what the issue was, but it was hardware related as it was sent back to the MFR.

When the Mits hc4000 had the issue, it appeared eerily similar to this, only a select few people were having problems, and it would only show up after hours of usage.

You may be right. The cable brand is Furui. I contacted the manufacturer since they quoted a lifetime guarantee. The guy says he will discuss with engineering and then later gets back to me. He says the pro version of the cable I bought might not be the best match for this projector and recommends a slightly different cable. As it happens I already have one of this other cable unopened because of the sale they were having. I thought the only difference was a braided cover on the pro one, but he says not. So he is sending me another of the non-braided ones to replace it.

I think the issue has to do with how the cable is powered. After talking with him, what really corrected it was not time/warmup; it was when I disconnected both ends of the cable at the same time. He seemed pretty confident, we'll see. I have not swapped it yet and it was fine tonight. I will probably just connect both cables since I have two ins and outs, then wait for it to happen again so I can try the other one immediately and see if it fixes.

thanks

I had it with 1.20 through the current 2.07 (and I only had 1.17 for a couple of days so I might have missed it). On the other hand, 2.07 was supposed to fix it (and apparently did for some people) but the replacement projector I got was good on both 2.06 and 2.07.

My educated guess is that it is a hardware problem with a (sometimes) firmware work-around.

There isn't much they can do with firmware to get around a HW issue, generally it's one or the other. However, the one exception they can do is change some of the operating environment variables I suppose to try to counteract the issue, but generally hardware is hardware and firmware is software.

I think I've seen about 10 cases of it in here. This problem has been going on and on for months. There's no way its just 3-4 people. One guy went about 400 hours until it hit.

The normal thing for someone that has this problem to do is to power cycle the projector and if it seems fine, they'd write it off. These projectors have likely not been in the hands of your clients long enough to burn through a couple 400-500 hour test cycles. You most likely would not hear about it unless it happened 2-3 times. I've seen many projector owners not put more than 400 hours on a projector in a whole year. So, while you might think your clients not reporting it means there's no issue, I think it is far more likely that many just haven't encountered it "yet" due to low use and also a few did and just power cycled without informing you.

On the e-shift models there is a similar problem that was never fixed (as far as I know). The screen would get filled with random lines and disconnecting the source would not fix it. I experienced the problem on a previous unit and thought my current one (an X750/RS500) does not have it, but finally saw it last week after 1000 hours.

Fortunately on the e-shift units turning off CMD would fix it (without having to power cycle the projector), but apparently the same trick does not work on the native 4K models.

My prior projector was an early model RS500. I experienced this problem in spades when I first installed the projector. I would get the random bars sometimes upon start up but mostly when switching sources. The only way to un freeze the bars was to power cycle. I finally mostly eliminated the problem by trying different HDMI cables until I found cables that worked. The cable that worked for me was Monoprice Certified Premium High Speed HDMI Cable, 4K @ 60Hz, HDR, 18Gbps, 28AWG, YUV 4:4:4, 6ft, Black. Not an expensive cable.

Last month I installed a new JVC NX9 in the system and experienced on occasion the same random vertical bars never on start up but occasionally upon switching. But, on the NX9, I found that power cycling to solve the problem was not required. All I had to do was switch to another source (either active or un active) until I saw a clear screen then switch back to the desired source. I mostly have experienced this with the Roku connection. Since the work around is easy and fast, I have not changed HDMI cables yet but feel that the HDMI handshake is the issue.

On either the RS500 or the NX9, I have never experienced a vertical bar issue while a program is playing. That appears to be a separate issue. I have logged about 50 hours on my NX9 (firmware 2.07) without this particular issue.

Mt thought is that both stability issues are HDMI related. The first is failure to achieve handshake and the second loss of HDMI connection during play back triggered by something in the image signal. It would appear that some units might be more sensitive to the conditions that trigger loss of signal.
This might be caused by a component on the edge of a speciation limit. This would account for random occurrences as well as some not experiencing the problem at all if component is not at spec edge.

I'm aware of all that. My main point was you don't see a bad DIMM or board capacitor for example be fine for a very long period of time after a simple power cycle. They will generally fail again as soon as they are stressed. Again if it was heat related I would think it would manifest again very quickly since you are resuming the same material that caused the overheat condition with only a brief interruption. Minutes rather than hours. But these are very complex devices so it's really hard to say. I could easily be wrong.

The symptoms just seem more like a corruption in memory somewhere. Cycling power clears volatile memory and it doesn't reoccur until a certain sequence results in corruption again. When it's fixed it will be interesting to know what it was. Hopefully they tell us.

It doesn't sound like software because of the way people are describing the problem, been in electronics and similar fields since the 1990's. I've seen this problem 5 times and it was never software, including on other projectors. That said, about 1 out of 3 or 4 times, software problems mimmick hardware and vice versa. So there is no way to really know for certain.

It's unusual to be able to run out of memory, it's protected and they'd have to be using some RTOS which probably have a sort of global error handler and garbage collector. The individual processing is outsourced I'm sure to companies that specialize in it, or a joint venture. With modern hardware, there is usually an overkill on firmware memory these days because it is so cheap. The HDMI decoders are pretty much standardized at this point, though some bugs do exist, they are usually just chroma bugs or conversion issues. Sounds like digital decoding failure of the HDMI signal from an out of phase electrical signal, they can fix it by implementing a more sensitive validity check on the signal before trying to decode it, but the reason these types of issues likely exist is because of video timing requirements and the real time OS requirement limits what can be done as far as how thorough the signals can be tested for validity without introducing extra lag.

You could say it is 'software' in the sense of not enough protection code to prevent the invalid decoding. However, for software, the error handler would likely just cause an HDMI resynch / blackout as it would default to trying to rehandshake. The fact that it hard locks and then shows lines, sounds like kernel panic, and the only thing that really causes kernel panics in RTOS is usually hardware failure or electrical signal problem (invalid signal). When the current is wrong or out of phase, the decoder itself fails and cannot read the signal, because it wasn't designed to decode that higher range. Eventually could damage the decoder chip or other chips, but unlikely it would because they generally can take a bit of a beating, it's just they can take more of a beating than they can actually 'read'.

Many projectors will lock up if you plug or unplug the HDMI cable in at exactly the wrong time, it's because sort of like how a 'spark' happens, you're basically sending a bad signal due to a split-second faulty connection as you were plugging it in. I think this is basically the same problem, except it's happening on a live signal. That's why they recommend not to hot plug HDMI cables (that and static discharge), though actually causing damage is very rare, but more commonly you can hard lock devices.

This might be caused by a component on the edge of a speciation limit. This would account for random occurrences as well as some not experiencing the problem at all if component is not at spec edge.
I agree it is most likely an HDMI signal problem, but the real question is whether it is software or an actual hardware issue. Given the frequency people had the issue, then the lack of the issue after swapping units, that's why I agree with you and don't think it's purely a software issue. There may very well be a software workaround though.

Switching sources can spike the signal and cause a similar issue, but more likely that only happens if you have a bad HDMI cable (or just a cable that cannot handle the spikes). With a good HDMI cable, the only way to usually cause it is by hot plugging / unplugging HDMI cables live. However, it sounds like people swapped cables I'm sure and were still having the same problem. This sounds a bit worse than the problem you were describing, as the NX series really shouldn't fail to decode the signal in the middle like that (without a source switch or hot plug), unless there was a bad cable (but then again people would have tried different cables).

The normal thing for someone that has this problem to do is to power cycle the projector and if it seems fine, they'd write it off. These projectors have likely not been in the hands of your clients long enough to burn through a couple 400-500 hour test cycles. You most likely would not hear about it unless it happened 2-3 times. I've seen many projector owners not put more than 400 hours on a projector in a whole year. So, while you might think your clients not reporting it means there's no issue, I think it is far more likely that many just haven't encountered it "yet" due to low use and also a few did and just power cycled without informing you.


I’ve counted 10 cases as well

Look at the difference in thickness between the two. The Peerless looks like a toy compared to the Chief.

I just got my replacement projector installed yesterday from the lines issue and haven't had time to test out where I've had problems in the past. To me it feels like some sort of HDMI handshake issue. I believe I've only seen it on the transitions between the FBI warnings. Which often results in the projector losing synch with the video source. Then it flips out and shoots out lines. The project either thinks its getting a continuous stream of lines or the output from the chip processing the HDMI signal is sending out a bunch of lines. The OSD doesn't show the lines over it so this shows that the projector thinks it should be displaying the lines. My issue could be when the projector just came on or when it had been on. It wasn't a heat issue.

It would be interesting to know if all those (10) who have had issues use a number of different sources?
I too believe it’s an HDMI issue when the projector is trying to sync, I wonder if this is why JVC had a very long sync on all the earlier models.
The NX series has a faster sync than the old models and could this be part of the problem, who knows…..

I only use an HTPC (one source) and all my 1500+ discs are ripped to the Nas, I have never seen these issues on my NX9 and I was one of the early adopters January 2019.
Since I only have one source there is only ever one handshake/sync at start-up, I don’t have the FBI warnings etc etc so there are no more syncs taking place once the projector is first fired up.

Food for thought…

Everything runs through my Lumagen to the JVC. I hadn't seen it on 1.17 or 2.01 in the 120 hours on my first RS3000 (December build received mid-Jan), but saw it after just 5 hours on my replacement (different issue) that came with 2.04 a couple of weeks ago. The first time I was out of the room and came back to it like that, but the second time it just happened while I was watching. No glitches in picture or audio, just the bars suddenly appearing. Both times I was watching TV from my DirecTV box with the Lumagen outputting 4096x2160 60p 4:2:2 12-bit. CMD etc off.

No issues with blue bars (or green) here after at least a couple hundred hours, and while I don't switch sources, I do switch apps and use all sorts of various media. The projector regularly changes between SDR and HDR, which switches lamp power, fan speed, color modes, and even engages the color filter. It also regularly changes frame rates, which also requires a new handshake. Finally, I switch back and forth between different anamorphic modes regularly. Netflix, Amazon, PSVue, and Plex (both TV and movies) and no bars. I watch between 2 and 5 hours at a sitting, seldom less or more. I haven't changed firmware from the 2.04 it came with.

I remember in the first couple hours it did something that required a hard power cycle, but I don't recall what it was specifically. I have had two cases where the shield had to be reset, but I thought it was the projector causing the problem because I figured I would see the Marantz logo if the shield dropped out, but instead I got the blue "no signal" screen. A shield reset fixed it.

I certainly hope I don't have any issues like others are reporting, but to be honest, it doesn't sound like something that makes it "inoperable". It sounds like an annoyance that certainly would warrant action on JVC's part if it continued, but something that will either eventually go away after a firmware update, or after a few dozen units get replaced. I'm not downplaying the significance of the reported issues, just not playing it up either.

The honest truth is that if it weren't for this thread, the ONLY issue I would be aware of with this projector is the bright corners, which stand out clear as day every time the projector goes to full black. And the fact is, I am in AWE at the picture quality every time I watch. Of all the money I have spent on various luxuries in my life, only a few have truly felt worth it after the first few uses. This projector is definitely one of them.

I can't help but feel there are some people posting on this thread that are doing their best to find a reason to hate these new projectors. The only time I see this much dedication toward blowing issues out of proportion is in politics. I can understand it in owners who have spent a lot of time and money and been shafted over and over with bugs and freight damage issues, but I'm not sure why a few non-owners are on that bandwagon too...?

Sorry, but a noisy DI and some blue bars every 100 hours that can be fixed with a reboot are NOT things that make this projector "inoperable". Annoying? Yes, without question. Disappointing? Of course. Would I be upset if I had the problems? Without a doubt. Would I return the projector and either go without anything or use something that wouldn't feel like it is worth the cost? Probably not. It would be different if the Sony was comparable in price and performance, or if the DLP's had the contrast and feature set, or if Epson had a true 4k panel and could still wipe the floor with their price point making their performance issues worth the savings, but the fact is, if you want solid native 4k performance at this caliber in the $10k range, there isn't a competitor.
